Clarity Through Grammar MechanicsQuestion 1 of 20

A city council is debating whether to replace a busy four-way stop near two schools with a roundabout. In a memo, the transportation director argues that roundabouts reduce severe crashes by slowing turning traffic and eliminating head-on collisions. The director notes that in the past three years, the intersection averaged 18 minor fender-benders annually and two injury crashes, mostly from hurried left turns during afternoon pickup. Some residents worry that students will be confused, but the director points out that nearby towns added roundabouts and reported fewer ambulance calls. After reviewing the crash reports, the director told the council the roundabout would make the intersection safer for students in a letter. Which revision most improves clarity of the bolded sentence?

Question 1

A city council is debating whether to replace a busy four-way stop near two schools with a roundabout. In a memo, the transportation director argues that roundabouts reduce severe crashes by slowing turning traffic and eliminating head-on collisions. The director notes that in the past three years, the intersection averaged 18 minor fender-benders annually and two injury crashes, mostly from hurried left turns during afternoon pickup. Some residents worry that students will be confused, but the director points out that nearby towns added roundabouts and reported fewer ambulance calls. After reviewing the crash reports, the director told the council the roundabout would make the intersection safer for students in a letter. Which revision most improves clarity of the bolded sentence?

  1. After reviewing the crash reports, the director told the council in a letter that the roundabout would make the intersection safer for students. (correct answer)
  2. After reviewing the crash reports, the director told the council the roundabout would make the intersection safer for students, in a letter.
  3. After reviewing the crash reports, the director told the council the roundabout would make students safer at the intersection in a letter.
  4. After reviewing the crash reports, the director, in a letter, told the council the roundabout would make the intersection safer for students, which was important.
Explanation: This question tests how modifier placement affects clarity through proper grammar and mechanics. The original sentence places "in a letter" at the end, creating ambiguity about whether the students are "in a letter" or the communication occurred "in a letter." Choice A correctly positions "in a letter" immediately after "told the council," making it clear that the letter was the medium of communication, not a description of where students are located. Choice B's placement after "students" creates the same ambiguity as the original, while Choice C suggests students themselves are "in a letter." When modifiers are misplaced, they attach to the nearest noun, creating unintended meanings—always position prepositional phrases immediately after what they modify.

Question 2

Read the following excerpt from a magazine essay (7 sentences). The writer argues that workplaces should reduce unnecessary meetings.

My office calendar is a mosaic of rectangles labeled "sync," "touch base," and "quick check-in." None of them are quick, and most of them exist to prove that we are busy. When a team meets without an agenda, the loudest voice fills the time like air in an empty jar. We often leave the conference room frustrated, having solved nothing, and the emails that follow make it worse. The problem is not collaboration; it is collaboration without purpose. A written plan, shared in advance, would let people think before they speak. If managers want productivity, they should treat meetings as a tool, not a habit.

Which change best clarifies meaning in the bolded sentence?

  1. We often leave the conference room frustrated, having solved nothing, and the emails that follow worsen the situation.
  2. We often leave the conference room frustrated; having solved nothing, the emails that follow make it worse.
  3. We often leave the conference room frustrated, having solved nothing, and following emails make it worse for us.
  4. We often leave the conference room, frustrated by nothing having been solved, and the emails that follow make the frustration worse. (correct answer)
Explanation: This question tests clarity through proper modification and clear pronoun reference. The correct answer (D) restructures the sentence to eliminate the ambiguous "it" by specifying that "the frustration" is what the emails make worse. The original construction leaves unclear what "it" refers to—the situation, the frustration, or something else entirely. Choice A maintains this ambiguity with "the situation," while B creates a dangling modifier where "the emails" illogically become the subject of "having solved nothing." Choice C's "make it worse for us" remains vague about what "it" represents. The key strategy is to replace ambiguous pronouns with specific nouns that clearly identify what is being discussed.

Question 3

A science teacher is defending the use of open-note quizzes. She argues that memorization matters, but real scientific work depends on using references accurately and interpreting data under constraints. She cites her own gradebook: students who struggled on closed-note quizzes often improved when allowed to annotate formulas and focus on explaining reasoning. Critics claim open-note quizzes are "too easy," yet the teacher notes that she writes questions requiring application, not recall. By allowing notes, students can demonstrate understanding rather than anxiety, they argue. Which revision eliminates ambiguity and improves sentence mechanics in the bolded sentence?

  1. By allowing notes, students can demonstrate understanding rather than anxiety, they argue.
  2. By allowing notes, students argue, they can demonstrate understanding rather than anxiety.
  3. By allowing notes, the teacher argues that students can demonstrate understanding rather than anxiety. (correct answer)
  4. By allowing notes, students can demonstrate understanding rather than anxiety; the argument is made.
Explanation: This question demonstrates how unclear pronoun references and misplaced phrases affect sentence clarity. The original sentence's "they argue" creates confusion about who is making the argument—students or teachers—and the sentence structure suggests students themselves are arguing while taking notes. Choice C correctly identifies the teacher as the one making the argument and uses a clear "that" clause to present the teacher's claim about what allowing notes accomplishes. Choices A and D maintain the ambiguous "they," while Choice B's interrupting "students argue" suggests students are making this argument about themselves. When presenting someone's argument, clearly identify the speaker and use subordinate clauses to distinguish claims from actions.

Question 4

A nonprofit is urging the city to convert an abandoned rail corridor into a bike-and-walking trail. The nonprofit argues that trails increase foot traffic for small businesses and provide safe routes for commuters who cannot afford cars. Some neighbors fear noise and trespassing, but the nonprofit points to studies showing that well-lit trails with clear entrances can reduce illegal dumping by increasing regular use. The group also notes that the corridor currently attracts broken glass and weeds, not families. While presenting the plan, the director promised to address residents' concerns about safety, lighting, and maintenance, which were frequent. Which revision most improves clarity of the bolded sentence?

  1. While presenting the plan, the director promised to address residents' frequent concerns about safety, lighting, and maintenance. (correct answer)
  2. While presenting the plan, the director promised to address residents' concerns about safety, lighting, and maintenance, which were frequent.
  3. While presenting the plan, the director promised to address residents' concerns, which were frequent, about safety, lighting, and maintenance.
  4. While presenting the plan, the director promised to address residents' concerns about safety, lighting, and maintenance, which were frequent among them in the neighborhood meetings that happened.
Explanation: This question shows how modifier placement affects clarity when multiple descriptors are present. The original sentence's "which were frequent" at the end could modify "maintenance" alone or all three concerns, creating ambiguity about what exactly was frequent. Choice A solves this by placing "frequent" directly before "concerns," making it clear that the concerns themselves (not just maintenance) were frequent. Choices B and D maintain the ambiguous "which" clause at the end, while Choice C's interrupting placement disrupts the flow without adding clarity. When multiple items in a series need modification, place the modifier before the entire series rather than after it to avoid ambiguity.

Question 5

A company is considering adopting a four-day workweek without reducing pay. Advocates argue that fewer days in the office can increase focus by forcing teams to prioritize essential meetings and reduce burnout. Skeptics worry that customer service will suffer, but a pilot program in one department showed response times stayed steady when employees rotated coverage. The CEO emphasizes that the change is not a perk but a productivity strategy tied to measurable outcomes. Employees reported feeling less stressed after the pilot ended, improving morale. Which revision best clarifies meaning in the bolded sentence?

  1. Employees reported feeling less stressed after the pilot ended, improving morale.
  2. Employees reported feeling less stressed after the pilot ended, which improved morale.
  3. After the pilot ended, employees reported feeling less stressed, and their reduced stress improved morale. (correct answer)
  4. Employees, after the pilot ended improving morale, reported feeling less stressed.
Explanation: This question illustrates how participial phrases can create ambiguity about cause and effect. The original sentence's structure makes it unclear whether the pilot ending improved morale or whether employees' reduced stress improved morale. Choice C provides the clearest revision by explicitly stating the causal relationship: employees felt less stressed after the pilot, AND this reduced stress improved morale. Choice A's participial phrase "improving morale" dangles ambiguously, Choice B's "which" could refer to the pilot ending rather than reduced stress, and Choice D creates a grammatically incorrect interruption. When showing cause-and-effect relationships, use explicit conjunctions and clear subjects rather than ambiguous modifiers.

Question 6

A local newspaper editorial argues that public libraries should expand their digital services, not shrink them. The writer notes that e-book checkouts in the county increased by 28% last year while physical circulation fell slightly. Critics claim that investing in apps and online databases will make libraries feel less "community-centered," but the editorial insists that access is the community's core value. It points out that job seekers use library Wi‑Fi and resume software, and students rely on online tutoring subscriptions the library negotiates at scale. To keep libraries relevant, the county should fund digital access for patrons who can't afford it, which the editorial calls essential. Which revision eliminates ambiguity in the bolded sentence?

  1. To keep libraries relevant, the county should fund digital access for patrons who can't afford it, which the editorial calls essential.
  2. To keep libraries relevant, the editorial calls the county's funding of digital access for patrons who can't afford it essential.
  3. To keep libraries relevant, the county should fund digital access for patrons who can't afford it; the editorial calls this funding essential. (correct answer)
  4. To keep libraries relevant, the county should fund digital access for patrons who can't afford it, an essential idea in the editorial's opinion for relevance.
Explanation: This question illustrates how sentence structure and punctuation enhance clarity in complex ideas. The original sentence's "which" clause creates ambiguity—it could modify "patrons," "access," or the entire preceding idea, leaving unclear what exactly is "essential." Choice C resolves this by creating two independent clauses separated by a semicolon, then uses the demonstrative "this funding" to specify exactly what the editorial considers essential. Choice A maintains the ambiguous "which," Choice B creates a confusing word order suggesting the editorial itself funds access, and Choice D adds unnecessary complexity. Using semicolons to separate related ideas and demonstrative pronouns to clarify references prevents readers from misinterpreting which element receives emphasis.

Question 7

A university is deciding whether to require a one-credit financial literacy course for all first-year students. Supporters argue that many students sign loan documents without understanding interest or repayment plans, and they cite campus survey results showing that 62% of freshmen cannot define "APR." Opponents say the curriculum is already crowded and that students can find budgeting advice online. The proposal's author responds that online advice is inconsistent and often tied to advertising. The committee recommended the course to the provost after meeting for three hours on Friday. Which revision most improves clarity of the bolded sentence?

  1. After meeting for three hours on Friday, the committee recommended the course to the provost. (correct answer)
  2. The committee recommended the course to the provost after meeting for three hours on Friday.
  3. After meeting for three hours, the committee recommended the course to the provost on Friday.
  4. Meeting for three hours on Friday, the committee recommended the course to the provost, which was a long time.
Explanation: This question tests how modifier placement affects temporal clarity in sentences. The original places "on Friday" at the end, creating ambiguity about whether the meeting or the recommendation occurred on Friday. Choice A correctly positions "on Friday" immediately after "three hours," making it clear that Friday was when the meeting happened, not when the recommendation was made. Choice B maintains the original ambiguity, Choice C suggests the recommendation itself happened on Friday after an earlier meeting, and Choice D adds an unnecessary and vague comment. Time-related modifiers should be placed immediately adjacent to the action they modify to prevent confusion about sequence and timing.

Question 8

A columnist argues that schools should replace punitive tardy policies with practical supports. She notes that students who arrive late often cite unreliable buses, sibling drop-offs, or shift work, not indifference. The columnist concedes that punctuality matters, but she argues that detentions can worsen the problem by keeping students after school and causing them to miss jobs or childcare. She proposes a "late start" room where tardy students quietly begin work and check in with a counselor. To reduce chronic tardiness, the columnist recommends meeting students where they are, literally. Which revision most improves clarity of the bolded sentence?

  1. To reduce chronic tardiness, the columnist recommends meeting students where they are, literally.
  2. To reduce chronic tardiness, the columnist recommends meeting students where they are—both figuratively and, in the case of transportation barriers, literally. (correct answer)
  3. To reduce chronic tardiness, the columnist recommends meeting students, where they are literally.
  4. To reduce chronic tardiness, the columnist recommends meeting students, literally, where they are in life and in school.
Explanation: This question shows how single-word modifiers can create ambiguity without context. The original sentence's ending "literally" could mean the columnist wants physical meetings at students' locations or is emphasizing the phrase "where they are" isn't metaphorical—but without context, readers can't determine which. Choice B provides the clearest revision by explicitly contrasting "figuratively" with "literally" and specifying that literal interpretation applies specifically to transportation barriers, not all situations. Choice A maintains the ambiguity, Choice C's comma placement is incorrect, and Choice D adds vague phrases without clarifying the literal/figurative distinction. When using potentially ambiguous intensifiers like "literally," provide enough context to guide interpretation.

Question 9

Read the following excerpt from a museum fundraising letter and answer the question.

Our museum's free-admission days are crowded for a reason: families want culture that doesn't require a second thought at the checkout counter. Yet free days are not actually free; they are subsidized by members and donors who cover staffing, security, and utilities. Last year, free-admission attendance increased by 18 percent, while the museum shop and café revenue rose as well, suggesting that access and sustainability can reinforce each other. The new membership tier would cost less than a monthly streaming service and would include early entry hours. By joining today, the exhibits can remain accessible to everyone. A small, predictable contribution is what turns a welcoming policy into a permanent one.

Which revision eliminates ambiguity in the bolded sentence?

  1. If you join today, you can help keep the exhibits accessible to everyone. (correct answer)
  2. By joining today, remaining accessible, the exhibits can be for everyone.
  3. By joining today, the museum's exhibits, accessible to everyone, can remain.
  4. By joining today, the exhibits can remain accessible, which is for everyone.
Explanation: This question tests clarity by addressing illogical subjects for action verbs. The original sentence illogically suggests "the exhibits" can join, when clearly people join to support the exhibits. Choice A corrects this by making "you" the subject who joins, with the clear result that your action helps keep exhibits accessible. Choice B maintains the illogical subject problem with exhibits "remaining accessible" through joining. Choice C suggests exhibits themselves can remain through joining. Choice D keeps the problematic structure where exhibits do the joining. The key strategy is to ensure that the grammatical subject of an action verb is capable of performing that action—exhibits cannot join, but people can.

Question 10

A university is debating whether to allow students to take more courses pass/fail. Advocates say it encourages intellectual risk-taking, especially in classes outside a student's major, and may reduce stress-related withdrawals. Critics argue it could weaken transcripts and make it harder for graduate programs to evaluate applicants. The university's data show that students who used pass/fail options were more likely to enroll in advanced electives later. Faculty members also note that letter grades can exaggerate small differences in performance. If the policy expands, advisors should explain it carefully to students, which can affect scholarships. Which revision eliminates ambiguity in the bolded sentence?

  1. If the policy expands, advisors should carefully explain to students that pass/fail choices can affect scholarships. (correct answer)
  2. If the policy expands, advisors should explain it carefully to students, which affects scholarships.
  3. If the policy expands, advisors should explain it carefully to students, affecting scholarships.
  4. If the policy expands, advisors should explain it carefully, which can affect scholarships, to students.
Explanation: This question tests grammar and mechanics, particularly embedding clauses to resolve ambiguous relative pronouns for greater clarity. Choice A rephrases to include 'that pass/fail choices can affect scholarships' as a noun clause object of 'explain,' making it clear that the effect on scholarships pertains to the choices, not the explaining or policy itself. This structure eliminates the vague 'which' by specifying what advisors should explain. The adverb 'carefully' is positioned to modify 'explain,' enhancing the instructional tone. Choice B leaves 'which affects scholarships' ambiguous, potentially referring to students or the policy. To avoid such issues, use 'that' clauses for direct objects in explanations, ensuring modifiers align precisely with their subjects.

Question 11

A company is considering switching to a four-day workweek without reducing pay. Managers say the change could improve retention and reduce burnout, while some clients worry about slower response times. In a three-month trial, output stayed steady, and sick days decreased. Employees reported using the extra day for errands and caregiving, which made them more focused during work hours. The company also found that meetings became shorter when teams had less time to waste. The CEO said the trial succeeded because employees were more productive, working fewer hours. Which revision most improves clarity of the bolded sentence?

  1. The CEO said the trial succeeded because employees were more productive while working fewer hours. (correct answer)
  2. The CEO said the trial succeeded because employees were more productive, and fewer hours were worked.
  3. The CEO said the trial succeeded because employees were more productive, working, fewer hours.
  4. The CEO said the trial succeeded because employees were more productive, which worked fewer hours.
Explanation: This question evaluates grammar and mechanics, highlighting the use of subordinating conjunctions to clarify temporal relationships for enhanced clarity. Choice A adds 'while working fewer hours' to indicate that productivity increased during the reduced hours, clearly modifying 'more productive' without dangling. This conjunction 'while' establishes the contrast, ensuring the reader understands the cause of success. The revision maintains parallel structure in the 'because' clause, aiding readability. Choice D misapplies 'which worked fewer hours' to 'productive,' illogically suggesting productivity itself worked fewer hours. Incorporate words like 'while' to show relationships in time or condition, preventing misreadings in explanatory contexts.

Question 12

Read the following excerpt from a technology newsletter (7 sentences). The writer argues that schools should teach students how recommendation algorithms shape attention.

Students can name dozens of influencers, yet many cannot explain why the same videos appear on their feeds every day. Adults call this "kids being online," but the pattern is engineered. A recommendation system rewards content that keeps people watching, not content that makes them wiser. After the platform noticed users paused on angry clips, it promoted them, which changed the tone of the app. Soon, even neutral topics were framed as fights, because conflict holds attention. Teaching media literacy means teaching incentives, not just telling students to "be careful." Schools should treat algorithms as a civic issue, not a niche tech topic.

Which revision eliminates ambiguity in the bolded sentence?

  1. After the platform noticed users paused on angry clips, it promoted those clips, changing the tone of the app. (correct answer)
  2. After noticing users paused on angry clips, the platform promoted them, which changed the tone of the app.
  3. After the platform noticed users paused on angry clips, it promoted them, which changed them.
  4. After the platform noticed users paused on angry clips, promotion occurred, which changed the tone of the app.
Explanation: This question addresses ambiguous pronoun reference that affects meaning clarity. The correct answer (A) replaces the ambiguous "them" with "those clips" and restructures to make clear that promoting the clips (not changing the clips themselves) changed the app's tone. The original "which changed them" could mean either the clips were changed or the tone was changed. Choice B maintains some ambiguity with "them," though it correctly identifies what changed. Choice C preserves the original ambiguity about what "them" refers to in "changed them." Choice D uses passive voice that obscures agency and clarity. The transferable strategy is to replace ambiguous pronouns with specific nouns and ensure the sentence structure clearly indicates what is acting upon what.

Question 13

A neighborhood association is urging the city to plant more street trees. Members argue that trees reduce urban heat, improve air quality, and make walking more pleasant, which can increase local shopping. Some residents worry about fallen branches during storms and the cost of watering young trees. The city's public works department reports that newer drought-tolerant species have lower maintenance needs, and a local nonprofit has offered volunteers for the first two years of care. During last summer's heat wave, temperatures on treeless blocks were measured several degrees higher than on shaded streets. Planting trees can cool the neighborhood, lowering temperatures on streets in summer. Which revision most improves clarity of the bolded sentence?

  1. Planting trees can cool the neighborhood by lowering summer street temperatures. (correct answer)
  2. Planting trees can cool the neighborhood, lowering temperatures on streets, in summer.
  3. Planting trees can cool the neighborhood, which lowers temperatures on streets in summer.
  4. Planting trees can cool the neighborhood, lowering temperatures, on streets in summer.
Explanation: This question assesses grammar and mechanics, stressing the addition of prepositions to clarify participial phrases and boost sentence clarity. Choice A introduces 'by lowering summer street temperatures' to explicitly show how planting trees cools the neighborhood, transforming the dangling participle into a clear adverbial phrase. This revision specifies 'summer street temperatures,' pinpointing the seasonal and locational context without ambiguity. The preposition 'by' links the action directly to the result, improving logical flow. Choice C uses 'which lowers,' but 'which' incorrectly modifies 'neighborhood,' suggesting it lowers temperatures. When dealing with methods or results, add 'by' to participial phrases to explicitly connect cause and effect in descriptive sentences.

Question 14

Read the following excerpt from an environmental blog post and answer the question.

A city can't compost its way out of every climate problem, but food waste is a sensible place to start. When scraps go to landfills, they decompose without oxygen and release methane, a potent greenhouse gas. Our pilot program collected curbside compost from 3,200 households and diverted an estimated 180 tons of organic waste in six months. Participation rose when the city provided clear rules about what counts as "compostable," because residents stopped guessing and contaminating bins with plastic. To reduce contamination, the city mailed residents a guide, listing common mistakes. Small interventions matter when they make the right behavior easier than the wrong one.

Which revision most improves clarity of the bolded sentence?

  1. To reduce contamination, the city mailed residents a guide that listed common mistakes. (correct answer)
  2. To reduce contamination, the city mailed residents a guide, and common mistakes were listed.
  3. To reduce contamination, mailing residents a guide, the city listed common mistakes.
  4. To reduce contamination, the city mailed residents, listing common mistakes, a guide.
Explanation: This question tests clarity through proper coordination of sentence elements and avoiding ambiguous modifiers. The original sentence places "listing common mistakes" as a participial phrase that could modify either "mailed" or "residents," creating confusion about who is doing the listing. Choice A resolves this by using a clear relative clause ("that listed common mistakes") to modify "guide," making it unambiguous that the guide contains the list. Choice B shifts to passive voice and loses the connection between the guide and the mistakes. Choice C incorrectly suggests the city is doing the mailing and listing simultaneously. Choice D creates an awkward interruption between "residents" and "a guide." The principle here is that relative clauses often provide clearer modification than participial phrases when ambiguity is possible.

Question 15

Read the following excerpt from a school-board op-ed (7 sentences). The writer argues that students need more time to read independently during the school day.

At last month's curriculum meeting, administrators celebrated a new "efficiency schedule" that trims five minutes from every class period. They argued that the reclaimed minutes, added together, will create space for test prep without "taking anything away." But reading is not a filler activity; it is the slow work that teaches students how to think in sentences longer than a slogan. When teachers lose even a few minutes, they cut the quiet parts first, because discussion and announcements feel urgent. By the end of the week, the schedule has stolen thirty minutes from students, which is enough time to finish a chapter sitting in the library. That loss is measurable, and so is the cost: fewer pages read, less stamina, and a narrower vocabulary. If the district wants higher scores, it should protect reading time rather than treating it as leftover.

Which revision most improves clarity of the bolded sentence?

  1. By the end of the week, the schedule has stolen thirty minutes from students, enough time to finish a chapter sitting in the library.
  2. By the end of the week, the schedule has stolen thirty minutes from students; sitting in the library, they have enough time to finish a chapter.
  3. By the end of the week, the schedule has stolen thirty minutes from students—enough time for students to sit in the library and finish a chapter. (correct answer)
  4. By the end of the week, the schedule has stolen thirty minutes from students, which is enough time to finish a chapter, sitting in the library.
Explanation: This question tests clarity through grammar and mechanics, specifically how punctuation and sentence structure affect meaning. The correct answer (C) uses an em dash to clearly connect "thirty minutes" with its purpose—"enough time for students to sit in the library and finish a chapter." This revision eliminates the dangling modifier problem in choices A and D, where "sitting in the library" awkwardly attaches to the wrong subject. Choice B's semicolon creates an illogical separation between the stolen time and its significance, making it seem like students are already sitting in the library rather than explaining what they could do with that time. The key strategy is to ensure modifiers clearly attach to their intended subjects and that punctuation logically connects related ideas.

Question 16

Read the following excerpt from a personal finance column (6 sentences). The writer argues that "buy now, pay later" plans should be regulated like credit.

The app on my phone offers to split a $120 purchase into four "easy payments," as if arithmetic could erase risk. The company insists it is not a lender because it does not charge interest on time. But fees appear the moment a payment is late, and late is common when budgets are tight. Because the plans are marketed to young shoppers, the debt feels temporary. That feeling is precisely the product: a sense that consequences belong to a future self. Regulators should treat these plans as credit, because that is how they function.

Which change best clarifies meaning in the bolded sentence?

  1. Because the plans are marketed to young shoppers, the debt feels temporary to them. (correct answer)
  2. Because the plans, marketed to young shoppers, the debt feels temporary.
  3. Because the plans are marketed to young shoppers, the debt, feeling temporary, is appealing.
  4. Because the plans are marketed to young shoppers, the debt feels temporary, which is marketed.
Explanation: This question tests clarity through complete sentence structure and clear pronoun reference. The correct answer (A) adds "to them" to clarify that the debt feels temporary specifically to young shoppers, not in general. This small addition eliminates ambiguity about whose perception is being described. Choice B creates a sentence fragment by omitting the verb, while C shifts the meaning by making the debt itself "appealing" rather than focusing on how it feels. Choice D creates confusion by unnecessarily repeating "marketed" in a way that obscures the main point. The key strategy is to ensure pronouns and their antecedents are clearly connected, even if it requires adding a prepositional phrase for clarity.

Question 17

Read the following excerpt from a public health article and answer the question.

Vaccine clinics succeed when they respect people's time. In our county, the highest no-show rates occurred at sites that required multiple forms, long lines, and unclear signage; the lowest rates occurred at pop-up clinics placed near grocery stores on weekends. The county's new plan focuses on predictable hours and walk-in access, not just more advertising. It also partners with local employers so workers can get vaccinated without losing pay. After texting reminders to patients, missed appointments fell, which the county expanded. The lesson is simple: convenience is not a luxury; it is infrastructure.

Which revision most improves clarity of the bolded sentence?

  1. After the county texted reminders to patients, missed appointments fell, so the county expanded the reminder program. (correct answer)
  2. After texting reminders to patients, missed appointments fell, which expanded the county.
  3. After texting reminders to patients, missed appointments fell, which the county expanded quickly.
  4. After texting reminders to patients, the county expanded missed appointments, which fell.
Explanation: This question tests clarity by addressing misplaced modifiers and unclear pronoun references that create illogical meanings. The original sentence suggests "the county expanded" (which makes no sense) due to the ambiguous "which" following "fell." Choice A completely restructures the sentence to create a clear cause-and-effect sequence: the county texted reminders, appointments fell as a result, and therefore the county expanded the program. This eliminates all ambiguity about what expanded and why. Choice B illogically suggests missed appointments expanded the county. Choice C maintains the ambiguity about what "which" refers to. Choice D creates the nonsensical meaning that the county expanded missed appointments. The key principle is to restructure sentences with ambiguous "which" clauses into clear, sequential statements of cause and effect.

Question 18

A columnist argues that schools should teach media literacy as a graduation requirement. The column describes how students encounter persuasive content daily, from influencer ads to political memes, yet rarely learn how algorithms shape what they see. The writer cites a study showing that students who practiced evaluating sources were less likely to share false headlines. The column proposes a semester course that includes identifying logical fallacies, checking claims against primary documents, and recognizing sponsored content. The writer concedes that adding a requirement is difficult but argues it is as essential as health class because misinformation spreads like a public hazard. When teachers assign research projects, they often rely on websites, which can mislead students. Which revision eliminates ambiguity in the bolded sentence?

  1. When teachers assign research projects, they often rely on websites, which can mislead students.
  2. When teachers assign research projects, students often rely on websites that can mislead them. (correct answer)
  3. When teachers assign research projects, relying on websites can mislead students often.
  4. When teachers assign research projects, websites are often relied on, which can mislead students.
Explanation: This question addresses clarity through fixing unclear pronoun reference, a mechanics issue that can completely change sentence meaning. The original sentence suggests teachers rely on websites when assigning projects, but the context indicates students are the ones relying on potentially misleading websites. Choice B corrects this by making "students" the subject of "rely" and using "that can mislead them" to modify "websites," creating a clear cause-and-effect relationship. Choice A maintains the error of having teachers as the subject of "rely," Choice C creates an awkward construction with misplaced "often," and Choice D uses passive voice that obscures who does the relying. The transferable principle is to ensure pronouns and their antecedents create logical meaning within the sentence's context.

Question 19

Read the following excerpt from a public health newsletter (about 185 words), then answer the question.

Every winter, the same pattern repeats: clinics overflow, employers scramble for coverage, and families debate whether a fever is "bad enough" to keep a child home. Vaccination is not a perfect shield, but it is the most reliable way to reduce severe illness across a community. Still, uptake remains uneven. Some people distrust the vaccine; others simply cannot get to a clinic during business hours.

This year, the county partnered with libraries to offer weekend flu shots. Librarians cleared meeting rooms, nurses brought portable refrigerators, and volunteers translated consent forms. The program worked best in neighborhoods where residents already used the library as a hub.

Before the first clinic opened, the county emailed reminders to residents in Spanish and English, reaching thousands. As written, the sentence makes it sound as if the reminders themselves were "in Spanish and English" or as if "reaching thousands" modifies the languages. The point is that the bilingual reminders reached thousands of residents.

Which change best clarifies meaning in the bolded sentence?

  1. Before the first clinic opened, the county emailed bilingual reminders to residents, reaching thousands. (correct answer)
  2. Before the first clinic opened, the county emailed reminders to residents, reaching thousands, in Spanish and English.
  3. Before the first clinic opened, the county emailed reminders to residents in Spanish and English, reaching the reminders' thousands.
  4. Before the first clinic opened, the county emailed reminders to residents, which were in Spanish and English, reaching thousands.
Explanation: This question focuses on clarity through proper modifier placement, a fundamental grammar skill for effective writing. The original sentence creates confusion by placing "in Spanish and English" after "residents," which could suggest the residents themselves are "in Spanish and English" rather than the reminders. Choice A resolves this ambiguity by repositioning "bilingual" as an adjective directly modifying "reminders," making it immediately clear that the reminders, not the residents, were in two languages. Choice B maintains the confusing placement with an awkward interruption, C creates the nonsensical phrase "the reminders' thousands," and D uses an interrupting relative clause that doesn't solve the core problem. The key strategy is to place modifiers directly adjacent to the words they modify, using precise adjectives when possible.

Question 20

A neighborhood association is pressuring the city to enforce existing noise ordinances more consistently. The association claims that late-night construction and amplified music have increased since new restaurants opened on the main street. Restaurant owners respond that the area was rezoned for mixed use and that occasional noise is part of a lively district. The association counters that predictability matters: residents can tolerate events when they are scheduled, but not random disruptions at 2 a.m. The association asked the city to ticket businesses that violate the ordinance regularly, not the ones that comply. Which revision most improves clarity of the bolded sentence?

  1. The association asked the city to ticket businesses that violate the ordinance regularly, not the ones that comply.
  2. The association asked the city to ticket businesses that regularly violate the ordinance, not businesses that comply with it. (correct answer)
  3. The association asked the city to ticket businesses that violate the ordinance, not regularly, but consistently.
  4. The association asked the city to ticket businesses, regularly, that violate the ordinance, not the ones that comply with the ordinance in the district.
Explanation: This question tests how adverb placement affects meaning in sentences with contrasts. The original sentence places "regularly" ambiguously—it could modify "ticket" (ticket regularly) or "violate" (regularly violate), creating confusion about whether the association wants regular ticketing or is targeting regular violators. Choice B eliminates this ambiguity by placing "regularly" directly before "violate," making it clear that the association wants tickets for businesses that are repeat offenders, not for all violators on a regular basis. Choice A maintains the ambiguity, Choice C nonsensically contrasts "regularly" with "consistently," and Choice D's excessive commas create further confusion. Adverbs should be placed immediately before the verbs they modify to prevent misinterpretation.
