How to use this quiz

Try each quiz question before looking at the correct answer. Use the explanations to review missed ideas, then come back to similar questions until the pattern feels familiar.

All questions

Question 1

Choose the grammatically correct sentence.

  1. Neither of them are right.
  2. Neither of them are correct.
  3. Neither of them were correct.
  4. Neither of them is correct. (correct answer)
Explanation: The word "neither" is singular, so it must take the singular verb "is," not "are" or "were." The most tempting error is using "are correct" because the nearby plural "them" makes the sentence sound acceptable, but the subject is still singular.

Question 2

Fix the dangling modifier: 'Walking home, rain fell.'

  1. Walking home, I felt the rain. (correct answer)
  2. Walking home, rain was felt.
  3. The rain fell, walking home.
  4. While walking home, it rained.
Explanation: The opening phrase must modify the person doing the walking, so the subject after it should be 'I,' not 'rain.' The tempting fix 'While walking home, it rained' still fails because 'it' cannot walk, leaving the modifier dangling.

Question 3

Choose the correctly punctuated list.

  1. Get these; food, water, maps.
  2. Get: food, water, and maps.
  3. Get these: food, water, maps. (correct answer)
  4. Get these, food, water, maps.
Explanation: A colon introduces a list when it follows a complete introductory phrase, and "Get these" is that phrase. The tempting version "Get: food, water, and maps" puts the colon right after the verb, splitting "get" from what you get, so it is wrong. Commas alone or a semicolon after "these" do not correctly introduce the list. Thus the right list is "Get these: food, water, maps."

Question 4

Which sentence contains a comma splice?

  1. The race ended; we left.
  2. The race ended, we left. (correct answer)
  3. The race ended we left.
  4. The race ended, so we left.
Explanation: A comma splice joins two complete sentences with only a comma. Both "The race ended" and "we left" are independent clauses, so "The race ended, we left" is the splice. The tempting wrong choice is the version with no punctuation, "The race ended we left," which is a fused sentence, not a comma splice, because it has no comma.

Question 5

Which version avoids an unclear pronoun?

  1. Al gave Bob his pen.
  2. Al gave Bob Al's pen. (correct answer)
  3. He gave Bob Al's pen.
  4. Al gave him Al's pen.
Explanation: Repeating Al's name instead of using a pronoun removes any doubt about who owns the pen. The tempting version 'Al gave Bob his pen' is unclear because 'his' could refer to either Al or Bob. The options using 'he' or 'him' also leave the antecedent unclear. Naming the owner directly makes the sentence unambiguous.

Question 6

In a commentary on disaster communication, the author argues that officials should avoid jargon during emergencies. The author references a survey in which residents misinterpreted the term "storm surge" as ordinary rainfall. The draft sentence reads: "Clear warnings save lives, especially when they tell people what to do, not what the weather is called." Which revision best improves clarity while preserving original meaning?

  1. Clear warnings save lives, especially when they tell people what to do rather than what the weather is called. (correct answer)
  2. Clear warnings save lives, especially when they tell people what to do, not what the weather is called, which matters.
  3. Clear warnings save lives, especially telling people what to do, not calling the weather what it is called.
  4. Clear warnings save lives; especially when they tell people what to do, not what the weather is called.
Explanation: This question addresses using grammar and mechanics for clarity by eliminating wordiness and improving parallel structure. The original sentence contains unnecessary wordiness with "what the weather is called" and awkward phrasing. Choice A fixes this by streamlining the contrast to "what to do rather than what the weather is called," which creates cleaner parallel structure and eliminates redundant phrasing. The revision maintains the distinction between actionable instructions and technical terminology while improving conciseness. Choices B, C, and D either retain wordiness, create grammatical errors, or use incorrect punctuation. Effective revision eliminates unnecessary words while maintaining parallel structure in comparisons.

Question 7

In an editorial about school start times, the author argues that later starts better match adolescent sleep cycles and cites a district pilot where tardiness fell by 12%. The author writes: The pilot mattered not only because grades rose, but also it showed families could adjust routines. Which revision best improves clarity while preserving original meaning?

  1. The pilot mattered not only because grades rose but also because it showed families could adjust routines. (correct answer)
  2. The pilot mattered not only because grades rose, but also showed families could adjust routines.
  3. The pilot mattered because not only grades rose, but also it showed families could adjust routines.
  4. The pilot mattered not only because grades rose, but also, it showed families could adjust routines.
Explanation: This question tests the skill of using grammar and mechanics for clarity in writing. The correct revision in choice A adds 'because' to the second part of the correlative structure 'not only...but also,' ensuring parallelism and clarifying the reasons why the pilot mattered. This balances the clauses, improving precision by making both parts grammatically equivalent. The revision preserves the emphasis on dual benefits without introducing redundancy. In contrast, choice B lacks parallelism by shifting from 'because' to 'showed,' which disrupts the sentence's logical structure. A transferable strategy is to mirror structures in correlative conjunctions like 'not only...but also' to maintain clarity in comparative sentences.

Question 8

In a feature about local journalism, the author argues that subscription models can support accountability reporting better than click-driven ads. The author cites a newsroom that hired two investigative reporters after reaching 3,000 subscribers. The draft includes: "Ads reward outrage, subscriptions reward reliability." Which sentence most effectively clarifies the author's point?

  1. Ads tend to reward outrage, while subscriptions tend to reward reliability.
  2. Ads reward outrage; subscriptions reward reliability. (correct answer)
  3. Ads, which reward outrage, subscriptions reward reliability.
  4. Ads reward outrage and subscriptions reward reliability, and that is why.
Explanation: This question focuses on using grammar and mechanics for clarity by improving conciseness and parallel structure. The original sentence is already grammatically correct, but Choice B creates a more concise and impactful version by eliminating unnecessary words. Removing "tend to" twice creates a cleaner parallel structure and makes the contrast more direct and powerful. The semicolon properly connects the two independent clauses while the parallel structure ("Ads reward...subscriptions reward") emphasizes the contrast between the two business models. Choices A, C, and D either retain wordiness, create grammatical errors, or add unnecessary explanatory phrases. Conciseness can strengthen contrasts and improve sentence impact.

Question 9

In an essay about community policing, the author argues that foot patrols can improve trust by increasing informal contact. The author cites a neighborhood survey showing a 12-point increase in residents who said they "recognize an officer by name." The draft includes: "Foot patrols create familiarity, this is different from surveillance." Which revision best improves clarity while preserving original meaning?

  1. Foot patrols create familiarity; this is different from surveillance. (correct answer)
  2. Foot patrols create familiarity, and this is different from surveillance, which is.
  3. Foot patrols, creating familiarity, this is different from surveillance.
  4. Foot patrols create familiarity, this being different from surveillance.
Explanation: This question tests using grammar and mechanics for clarity by correcting comma splice errors. The original sentence incorrectly joins two independent clauses with only a comma, creating a comma splice that disrupts the logical flow between related ideas. Choice A fixes this by replacing the comma with a semicolon, which properly connects the two independent clauses about foot patrols creating familiarity and how this differs from surveillance. The semicolon maintains the relationship between the ideas while providing correct punctuation that allows readers to understand the distinction being made. Choices B, C, and D either retain the comma splice or create new grammatical errors that obscure the intended meaning. Semicolons effectively connect independent clauses that elaborate on related concepts.

Question 10

In an editorial about remote work, the author argues that flexibility should be measured by outcomes rather than by visible busyness. The author notes that one team reduced meeting time by 40% while maintaining project deadlines. The draft sentence reads: "Remote work succeeds when expectations are explicit, not when employees are constantly monitored." Which revision best improves clarity while preserving original meaning?

  1. Remote work succeeds when expectations are explicit rather than when employees are constantly monitored. (correct answer)
  2. Remote work succeeds when expectations are explicit, not when employees are constantly monitored.
  3. Remote work succeeds when expectations are explicit, not constantly monitoring employees.
  4. Remote work succeeds, when expectations are explicit not when employees are constantly monitored.
Explanation: This question tests using grammar and mechanics for clarity by maintaining parallel structure in contrasts. The original sentence creates an effective contrast but Choice A improves it by using "rather than when" to create better parallel structure with "when expectations are explicit rather than when employees are constantly monitored." This creates clearer parallelism between two conditional situations being contrasted. The revision maintains the original meaning about what makes remote work successful while improving the grammatical structure of the comparison. Choices B, C, and D either create less effective parallelism or add unnecessary punctuation that disrupts the contrast. Strong parallel structure in comparisons helps readers understand the relationship between contrasting conditions or approaches.

Question 11

In an argument about reducing single-use packaging, the author notes that a local ordinance cut plastic bag distribution by 70% in one year. The author writes: Customers brought their own bags more often, consequently, stores ordered fewer plastic ones. Which revision best improves clarity while preserving original meaning?

  1. Customers brought their own bags more often; consequently, stores ordered fewer plastic ones. (correct answer)
  2. Customers brought their own bags more often, consequently stores ordered fewer plastic ones.
  3. Customers brought their own bags more often, and consequently, and stores ordered fewer plastic ones.
  4. Consequently, customers brought their own bags more often, stores ordered fewer plastic ones.
Explanation: This question tests the skill of using grammar and mechanics for clarity in writing. The correct revision in choice A inserts a semicolon before the conjunctive adverb 'consequently,' properly connecting the independent clauses and fixing the comma splice in the original. This punctuation clarifies the cause-and-effect relationship, improving logical flow and readability. The structure preserves the original meaning by emphasizing the result of customers' actions. In contrast, choice B omits necessary punctuation, resulting in a run-on sentence that reduces clarity. A transferable strategy is to use semicolons with conjunctive adverbs to clearly link cause and effect in explanatory writing.

Question 12

A student editorial argues that cities should replace some downtown parking with protected bike lanes because it improves safety, reduces congestion, and supports local businesses. In the draft below, one sentence is wordy and slightly unclear.

Draft excerpt: The author notes that protected lanes separate cyclists from traffic, and cites a local survey showing that most riders avoid streets without barriers. Because the lanes would be installed on streets that are already maintained by the city, the cost, which is often described as "too high," is actually lower than many people assume.

Which revision best improves clarity while preserving original meaning?

  1. Since the lanes would be installed on streets already maintained by the city, the cost—often described as "too high"—is actually lower than many people assume. (correct answer)
  2. The lanes would be installed on streets that are already maintained by the city, and the cost is lower than many people assume, which is often described as "too high."
  3. Because the lanes would be installed on streets that are already maintained by the city, the cost is actually lower than many people assume, and it is often described as "too high."
  4. Because the lanes would be installed on streets, the cost is lower, which many people assume is actually "too high," as the city already maintains them.
Explanation: This question tests using grammar and mechanics for clarity by asking students to revise a wordy sentence with multiple embedded clauses. The correct answer (A) improves precision and readability by using a dash to set off the parenthetical comment about cost being "too high," creating a cleaner sentence structure that maintains the logical flow from cause (lanes on existing streets) to effect (lower cost). This revision eliminates the awkward "which is" construction and places the descriptive phrase right after "cost" where it belongs. Option B incorrectly suggests the phrase "too high" describes when the cost is lower, creating a logical contradiction. The most effective strategy is to identify the core subject-verb-object relationship first, then determine the clearest way to incorporate additional information without disrupting that foundation.

Question 13

A policy memo argues that cities should plant more street trees because they reduce heat, improve air quality, and lower energy use. One sentence's parallel structure is inconsistent.

Draft excerpt: The memo cites a summer when pavement temperatures reached record highs and emergency rooms saw more heat-related illness. Street trees cool sidewalks, they filter pollutants, and providing shade for bus stops.

Which revision best improves readability?

  1. Street trees cool sidewalks, filter pollutants, and provide shade for bus stops. (correct answer)
  2. Street trees cool sidewalks, they filter pollutants, and they are providing shade for bus stops.
  3. Street trees cool sidewalks, filtering pollutants, and shade is provided for bus stops.
  4. Street trees cool sidewalks; they filter pollutants; and providing shade for bus stops.
Explanation: This question tests using grammar and mechanics for clarity by establishing parallel structure in a series of actions. The correct answer (A) maintains consistent verb forms—"cool," "filter," and "provide"—creating a smooth, readable list of what street trees do. This parallel construction helps readers process the information efficiently and emphasizes that these are three equal benefits. Option B incorrectly mixes a comma splice ("they filter") with inconsistent verb forms, C shifts from active verbs to a passive construction ("shade is provided"), and D combines semicolons with a participial phrase that breaks the pattern. When listing multiple actions or qualities, maintain the same grammatical form throughout to enhance both clarity and rhetorical impact.

Question 14

A city council member argues that expanding late-night bus service is a practical safety measure: it reduces drunk driving, gives hospital staff reliable rides, and keeps service workers from walking long distances after midnight. In the draft below, the writer wants to revise the bolded sentence for clarity.

Because the buses run only until 11 p.m., which is when many restaurant shifts end, riders are forced into paying for rideshares or walking home, both options are expensive or unsafe.

Which revision best improves clarity while preserving original meaning?

  1. Because the buses run only until 11 p.m., which is when many restaurant shifts end, riders are forced into paying for rideshares or walking home, both options being expensive or unsafe.
  2. Because buses stop running at 11 p.m.—when many restaurant shifts end—riders must either pay for rideshares or walk home, options that are expensive or unsafe. (correct answer)
  3. Buses run only until 11 p.m., and many restaurant shifts end then, which forces riders into paying for rideshares or walking home, and those options are expensive or unsafe for them.
  4. Because riders are forced into paying for rideshares or walking home, both options are expensive or unsafe, the buses run only until 11 p.m., when many restaurant shifts end.
Explanation: This question tests using grammar and mechanics for clarity by asking you to revise a sentence with multiple structural issues. The correct answer (B) improves precision and readability by using dashes to set off the parenthetical information "when many restaurant shifts end," creating a cleaner flow than the original's awkward "which is when" construction. Additionally, choice B eliminates the confusing phrase "both options being expensive or unsafe" by directly stating "options that are expensive or unsafe," making the relationship between the two alternatives clearer. Choice A's dangling phrase "both options being expensive or unsafe" creates ambiguity about what exactly is expensive or unsafe. The key strategy is to identify parenthetical elements and use appropriate punctuation (dashes, commas, or parentheses) to integrate them smoothly while maintaining clear subject-verb-object relationships.

Question 15

A community organizer argues that planting trees is a public-health strategy, not just beautification: shaded sidewalks encourage walking, and lower surface temperatures reduce heat-related illness. The writer wants to revise the bolded sentence to fix faulty parallelism.

The plan will lower temperatures, improving air quality, and it will make streets more walkable.

Which revision best improves clarity while preserving original meaning?

  1. The plan will lower temperatures, improve air quality, and make streets more walkable. (correct answer)
  2. The plan will lower temperatures, improving air quality, and streets will be made more walkable by it.
  3. The plan will lower temperatures, and improving air quality, and it will make streets more walkable.
  4. The plan will lower temperatures, and it will improve air quality, and by doing so making streets more walkable.
Explanation: This question tests using grammar and mechanics for clarity by fixing faulty parallelism in a series. The correct answer (A) creates perfect parallel structure with three future-tense verbs: "will lower," "(will) improve," and "(will) make," where the auxiliary "will" is understood to carry over to all three verbs. The original mixes a future-tense verb ("will lower"), a participial phrase ("improving"), and another future-tense construction ("it will make"), creating an unbalanced series. Choice B similarly mixes active and passive voice, while C incorrectly uses "and" before a participial phrase. The transferable strategy is to ensure all items in a series follow the same grammatical pattern, whether that's all nouns, all verbs in the same tense, or all phrases of the same type.

Question 16

In a feature about community gardens, the author argues that shared green space can improve neighborhood cohesion. The author notes that gardeners organized a tool-sharing system and began hosting monthly potlucks. The draft sentence reads: "The garden gave neighbors a reason to talk, and over time it made the block feel safer." Which revision best improves clarity while preserving original meaning?

  1. The garden gave neighbors a reason to talk, and over time it made the block feel safer.
  2. The garden gave neighbors a reason to talk; over time, it made the block feel safer. (correct answer)
  3. The garden gave neighbors a reason to talk; and over time it made the block feel safer.
  4. The garden gave neighbors a reason to talk, over time making the block feeling safer.
Explanation: This question addresses using grammar and mechanics for clarity by improving punctuation for better sentence flow. While the original sentence uses "and" to connect the ideas, Choice B uses a semicolon followed by a comma to create better separation between the immediate effect (giving neighbors a reason to talk) and the long-term result (making the block feel safer). The semicolon properly connects the related independent clauses while the comma after "over time" sets off the temporal transition phrase. This creates clearer emphasis on the progression from immediate to long-term community benefits. Choices A, C, and D either create less effective emphasis or grammatical errors. Strategic punctuation can improve the clarity of temporal relationships in cause-and-effect sequences.

Question 17

In a feature about public transit, the author argues that reliability matters more than flashy expansions. The author notes that when buses arrived within a 5-minute window, ridership increased even without new routes. The draft includes: "Riders don't check a schedule when the bus comes every ten minutes, they just show up." Which revision best improves clarity while preserving original meaning?

  1. Riders don't check a schedule when the bus comes every ten minutes; they just show up. (correct answer)
  2. Riders don't check a schedule when the bus comes every ten minutes, and they just show up, basically.
  3. Riders don't check a schedule, when the bus comes every ten minutes they just show up.
  4. Riders don't check a schedule when the bus comes every ten minutes showing up.
Explanation: This question tests using grammar and mechanics for clarity by correcting comma splice errors. The original sentence incorrectly joins two independent clauses with only a comma, creating a comma splice that disrupts the logical flow of ideas. Choice A fixes this by replacing the comma with a semicolon, which properly connects the two related independent clauses about rider behavior and bus frequency. The semicolon maintains the causal relationship while providing correct punctuation that helps readers understand the connection between reliable service and passenger habits. Choices B, C, and D either retain the comma splice, create sentence fragments, or add unnecessary wordiness. Proper punctuation between independent clauses clarifies cause-and-effect relationships.

Question 18

In a report about recycling, the author argues that "wish-cycling" (tossing nonrecyclables into bins) increases costs. The author cites a facility manager who said contamination forced staff to discard 12% of incoming loads. The draft sentence reads: "When people put greasy pizza boxes in the bin, it contaminates paper, raising processing costs." Which sentence most effectively clarifies the author's point?

  1. When people put greasy pizza boxes in the bin, they contaminate paper and raise processing costs. (correct answer)
  2. When greasy pizza boxes are in the bin, paper is contaminated, and processing costs are raised by it.
  3. Putting greasy pizza boxes in the bin contaminates paper, which is raising processing costs, which is bad.
  4. When people put greasy pizza boxes in the bin, it contaminates paper, and processing costs are raising.
Explanation: This question tests using grammar and mechanics for clarity by correcting unclear pronoun reference and improving sentence structure. The original sentence uses "it" without a clear antecedent, making it ambiguous what contaminates the paper. Choice A fixes this by specifying that "people" contaminate paper and using active voice to clarify the cause-and-effect relationship. The revision also changes "raising" to "raise" for proper parallel structure with "contaminate." This creates a clearer sequence of actions: people put boxes in bins, which contaminates paper and raises costs. Choices B, C, and D either retain pronoun ambiguity, use awkward passive voice, or create other grammatical issues. Clear pronoun reference and active voice help readers understand who does what.

Question 19

In an editorial about arts funding, the author argues that small grants can have outsized community impact. The author notes that a $5,000 mini-grant funded a free concert series attended by 900 residents. The draft includes: "The grant was small, but it paid for sound equipment, permits, and it hired local musicians." Which revision best improves clarity while preserving original meaning?

  1. The grant was small, but it paid for sound equipment, permits, and hiring local musicians. (correct answer)
  2. The grant was small, but it paid for sound equipment, permits, and it hired local musicians.
  3. The grant was small, but paying for sound equipment and permits, and it hired local musicians.
  4. The grant was small, but it paid for sound equipment, permits, and it was hiring local musicians.
Explanation: This question addresses using grammar and mechanics for clarity by creating parallel structure in a series. The original sentence has faulty parallelism in the series: "sound equipment, permits, and it hired local musicians"—mixing noun phrases with a complete clause. Choice A fixes this by making all three items parallel noun phrases: "sound equipment, permits, and hiring local musicians." The revision maintains the original meaning about what the grant funded while ensuring grammatical consistency throughout the series. Choices B, C, and D retain the faulty parallelism or create new grammatical errors. Parallel structure in series helps readers process lists of related items more easily and clearly.

Question 20

In a museum magazine, the author argues that labeling artifacts with brief stories (not just dates) increases visitor engagement. The author cites a week-long trial in which average time spent in a gallery rose from 11 to 16 minutes. The draft includes: "The labels were rewritten in plain language, this choice made the exhibit less intimidating." Which revision best improves clarity while preserving original meaning?

  1. The labels were rewritten in plain language; this choice made the exhibit less intimidating. (correct answer)
  2. The labels, rewritten in plain language, this choice made the exhibit less intimidating.
  3. Rewriting the labels in plain language, the exhibit was less intimidating by this choice.
  4. The labels were rewritten in plain language, and this choice, which was important, made the exhibit less intimidating.
Explanation: This question tests using grammar and mechanics for clarity by correcting comma splice errors. The original sentence incorrectly joins two independent clauses with only a comma, creating a comma splice that disrupts readability. Choice A fixes this by adding a semicolon between the clauses and using "this choice" to clearly reference the rewriting action. The revision maintains the causal relationship while providing proper punctuation to separate the related but independent ideas. Choices B, C, and D either retain the comma splice, create dangling modifiers, or add unnecessary wordiness. When connecting independent clauses, use semicolons or coordinating conjunctions with commas to ensure grammatical clarity.
