Integrate Evidence With CommentaryQuestion 1 of 20

Read the paragraph below from an argumentative essay about school policy.

Claim: Schools should adopt later start times because doing so measurably improves student learning.

Paragraph: A district in Minnesota shifted its high school start time from 7:25 a.m. to 8:30 a.m. After the change, the district reported that first-period failure rates dropped from 14% to 8% and average attendance rose by 1.7 percentage points. This shows that when school starts later, students do better in first period and come to school more often.

Which revision of the bolded commentary would best explain the significance of the evidence in relation to the paragraph's claim?

This proves that Minnesota schools are better than other schools because they care more about attendance.
Because first period is typically when sleep-deprived students struggle most, the drop in failures suggests that later start times reduce fatigue-related learning barriers, making academic gains more likely across the entire day—not just in one class period.
The numbers are important, and educators should pay attention to them when considering schedule changes.
This means that failure rates dropped from 14% to 8% and attendance increased by 1.7 percentage points.

All questions

Question 1

Read the paragraph below from an argumentative essay about school policy.

Claim: Schools should adopt later start times because doing so measurably improves student learning.

Paragraph: A district in Minnesota shifted its high school start time from 7:25 a.m. to 8:30 a.m. After the change, the district reported that first-period failure rates dropped from 14% to 8% and average attendance rose by 1.7 percentage points. This shows that when school starts later, students do better in first period and come to school more often.

Which revision of the bolded commentary would best explain the significance of the evidence in relation to the paragraph's claim?

  1. This proves that Minnesota schools are better than other schools because they care more about attendance.
  2. Because first period is typically when sleep-deprived students struggle most, the drop in failures suggests that later start times reduce fatigue-related learning barriers, making academic gains more likely across the entire day—not just in one class period. (correct answer)
  3. The numbers are important, and educators should pay attention to them when considering schedule changes.
  4. This means that failure rates dropped from 14% to 8% and attendance increased by 1.7 percentage points.
Explanation: This question tests the skill of integrating evidence with commentary by asking which revision best explains why the Minnesota data matters to the claim about improved learning. Choice B succeeds because it connects the specific evidence (first-period failure rates dropping) to the mechanism behind the claim (reduced fatigue-related barriers), explaining how better morning performance suggests all-day academic benefits. Choices A and C fail by making unsupported generalizations or offering vague observations without linking evidence to claim. Choice D merely restates the numbers without interpretation. The key writing principle is that effective commentary must explain the causal relationship between evidence and claim, not just summarize data or make broad assertions.

Question 2

A student is revising a paragraph arguing that cities should invest in urban tree planting. The paragraph's claim is: Increasing tree canopy reduces heat-related health risks in low-income neighborhoods.

Evidence included: A city health department map analysis found that neighborhoods with less than 10% canopy averaged summer surface temperatures 7°F higher than neighborhoods with more than 30% canopy; the same low-canopy areas also had the highest rates of heat-related emergency calls.

The commentary after the evidence is "Places with fewer trees are hotter and have more emergency calls."

Which revision of the bolded commentary would best explain the significance of the evidence for the paragraph's claim?

  1. By linking low canopy to both higher temperatures and more heat-related emergencies, the data suggests trees function as a public-health intervention—especially in neighborhoods already experiencing the most heat stress. (correct answer)
  2. The analysis compared neighborhoods with less than 10% canopy to those with more than 30% canopy.
  3. This shows that emergency calls are caused only by a lack of trees, not by any other factor.
  4. Trees make neighborhoods look nicer and can raise property values for homeowners.
Explanation: The rhetorical goal is to integrate evidence with commentary by linking tree canopy levels to reduced heat-related health risks in low-income areas, supporting the paragraph's claim. Choice A achieves this by connecting low canopy to higher temperatures and emergencies, positioning trees as a health intervention in stressed neighborhoods. It clarifies the evidence's significance by showing causal relationships and targeting vulnerable areas, enhancing the claim's focus on public health. This revision adds interpretive depth, explaining why the data advocates for investment. Choice B distracts by merely comparing canopy percentages without analyzing health implications. The transferable principle is that effective commentary elucidates how evidence advances the claim, a skill honed in AP English Language essay assessments.

Question 3

Read the paragraph below from an argumentative essay about digital privacy.

Claim: Companies should make privacy settings opt-in rather than opt-out to ensure meaningful user consent.

Paragraph: A 2019 study in the journal Behaviour & Information Technology found that when a data-sharing box was pre-checked, a large majority of participants left it selected; when the same box was unchecked by default, far fewer participants chose to share. Defaults change what people click.

Which revision of the bolded commentary would best explain why the evidence matters for the claim?

  1. Because default settings strongly steer user behavior, an opt-out design can manufacture "consent" that reflects inertia rather than intention; making sharing opt-in better aligns data collection with deliberate choice. (correct answer)
  2. This means the box was pre-checked in one condition and unchecked in the other condition.
  3. This is important because privacy is a major topic in society today, and people talk about it often.
  4. This demonstrates that users prefer to share their data and would rather not have any privacy settings at all.
Explanation: This question evaluates the ability to explain why evidence about default settings matters for a claim about meaningful consent. Choice A provides sophisticated commentary by explaining the psychological mechanism at work (defaults steer behavior through inertia) and connecting this to the ethical principle in the claim (consent should reflect deliberate choice). This goes beyond summarizing the study to explain its implications for privacy policy. Choice B merely restates the experimental design, C offers vague generalities, and D misinterprets the evidence entirely. The writing principle demonstrated is that effective commentary must explain the underlying principle or mechanism that makes evidence relevant to the claim.

Question 4

A student's essay claims that providing free school meals to all students improves academic outcomes by reducing hunger-related distraction. The paragraph includes evidence, but the added reasoning introduces an unsupported leap.

Paragraph excerpt: Universal free meals can reduce stigma and ensure students eat consistently. In one statewide rollout, a department of education report noted that breakfast participation increased by 18% after meals became free for all students. Therefore, test scores will immediately rise across the state.

Why does the evidence fail to fully support the claim as written?

  1. The evidence is about increased meal participation, but it does not provide data linking participation to academic outcomes or show that test scores changed, so the conclusion is an unsupported leap. (correct answer)
  2. The evidence fails because an 18% increase is too small to matter in any context.
  3. The evidence fails because breakfast participation can never be measured accurately.
  4. The evidence fails because universal meals only affect teachers, not students.
Explanation: The rhetorical goal is to assess how evidence integrates with commentary to support the claim that free school meals improve academic outcomes by reducing hunger distractions. Choice A accurately explains the failure by pointing out that meal participation data doesn't link to academics or show score changes, making the conclusion an unsupported leap. It highlights the gap between evidence and the claimed outcome, underscoring the need for direct connections. This reveals why the reasoning doesn't fully back the claim. Choice B distracts by dismissing the increase as insignificant without addressing the logical disconnect. A transferable principle is that commentary must logically tie evidence to claims without leaps, essential for credible argumentation in AP English Language exams.

Question 5

Read the body paragraph from an editorial about remote work.

Claim: Allowing remote work at least two days a week improves employee retention without harming productivity.

Paragraph: After the accounting firm Marlow & Co. adopted a hybrid policy, its HR department reported annual turnover fell from 22% to 14% the following year. However, the same internal memo notes that the company did not change its salary bands during that period. This shows turnover fell and salaries stayed the same.

Which revision of the bolded commentary best explains the significance of the salary detail in supporting the claim?

  1. This proves that remote work always increases profits for every company.
  2. This is important because it suggests the retention gain is less likely to be explained by higher pay, strengthening the inference that the hybrid policy itself contributed to employees staying. (correct answer)
  3. This is important because turnover is when employees leave, and salary bands are pay ranges.
  4. This shows the memo said turnover fell from 22% to 14% and that salary bands did not change.
Explanation: This question tests understanding of how to use commentary to address potential alternative explanations when integrating evidence. The correct answer (B) acknowledges that unchanged salary bands "strengthen the inference that the hybrid policy itself contributed to employees staying" by ruling out higher pay as the cause of improved retention. This sophisticated commentary anticipates reader skepticism by explaining why the salary detail matters—it eliminates a competing explanation for the retention improvement. Choice D simply restates both facts without showing their relationship, while A makes an unsupported universal claim. The writing principle here is that effective commentary often needs to explain not just what evidence shows, but what it rules out, especially when making causal claims.

Question 6

A student is drafting a paragraph for an essay claiming that libraries remain essential civic institutions because they provide equitable access to technology. The student wants to strengthen the link between evidence and claim.

Paragraph excerpt: Public libraries increasingly function as free technology hubs. According to a 2021 Pew Research Center report, 23% of Americans who do not have home broadband say they have used a public library's Wi‑Fi to access the internet. [Add a sentence here.] Without reliable internet, people struggle to apply for jobs, complete school assignments, or access government services that have moved online.

Which sentence would most effectively be added at the underlined point to connect the evidence to the paragraph's claim?

  1. Libraries have many books, and people can also borrow movies and music.
  2. Because nearly a quarter of those without home broadband rely on library Wi‑Fi, libraries help close the digital divide by offering access that would otherwise be limited by income or geography. (correct answer)
  3. This statistic is from 2021, and Pew Research Center publishes many different reports.
  4. This proves the government should ban internet service providers from charging for home internet.
Explanation: The rhetorical goal is to integrate evidence with commentary by connecting the Pew Research data on library Wi-Fi use to the claim that libraries provide equitable technology access as essential civic institutions. Choice B effectively bridges this by highlighting how the statistic addresses the digital divide, showing libraries offer vital access limited by income or location. It interprets the evidence to demonstrate libraries' role in promoting equity, directly supporting the claim with real-world implications. This addition strengthens the paragraph by explaining the data's broader significance for underserved populations. Choice A distracts by shifting focus to unrelated library services like books and media, failing to tie back to technology access. In writing, effective commentary elucidates evidence's relevance to the claim, a core skill for integrating sources in AP English Language compositions.

Question 7

A student argues that schools should start classes later because later start times improve teen health and learning. The paragraph includes evidence, but the commentary does not fully explain why the evidence matters.

Paragraph excerpt: Teenagers' sleep cycles naturally shift later, making early mornings especially difficult. The American Academy of Pediatrics has recommended that middle and high schools start at 8:30 a.m. or later, citing research linking insufficient sleep to attention problems and lower academic performance. This shows that doctors think later start times are better.

Which revision of the bolded commentary would best explain the significance of the evidence?

  1. This shows that doctors think later start times are better, and doctors usually know what is best.
  2. Because the recommendation ties later start times to reduced sleep deprivation and improved attention, it supports the claim that shifting schedules is not a convenience issue but a health-based intervention likely to benefit learning. (correct answer)
  3. This means the American Academy of Pediatrics recommended 8:30 a.m. or later for schools.
  4. This proves that students should never have homework, since sleep is the only cause of academic performance.
Explanation: The rhetorical goal is to integrate evidence with commentary by linking the American Academy of Pediatrics' recommendation to the claim that later school start times enhance teen health and learning. Choice B excels by explaining how the recommendation addresses sleep deprivation and attention issues, framing later starts as a health intervention that benefits academic performance. It connects the evidence to the claim by emphasizing its basis in research on sleep's role in learning, adding depth to the argument. This interpretation shows the evidence's significance beyond a simple endorsement, making the case more robust. Choice A, however, acts as a distractor by vaguely restating that doctors approve without exploring why this matters for health and learning. A transferable principle is that commentary should analyze evidence's implications for the claim, helping writers build reasoned arguments in AP essay tasks.

Question 8

A student is revising a body paragraph from an argumentative essay about school start times. The paragraph's claim is: Later start times improve student learning by increasing sleep and reducing tardiness.

The paragraph includes this evidence: A district report from 2023 found that after the high school moved its start time from 7:25 a.m. to 8:30 a.m., average first-period tardies dropped from 18 per day to 7 per day over one semester.

The writer's commentary after the evidence is "This shows that when school starts later, fewer students are late."

Which revision of the bolded commentary would best explain the significance of the evidence in relation to the paragraph's claim?

  1. Fewer tardies suggest that students are arriving more consistently and ready to participate, which protects instructional time and supports learning gains the claim links to better-rested students. (correct answer)
  2. The report says tardies dropped from 18 per day to 7 per day after the start time changed.
  3. This proves that later start times automatically raise test scores in every subject for all students.
  4. Tardiness is a problem in many schools, so districts should consider changing their schedules.
Explanation: The rhetorical goal in this revision is to integrate evidence with commentary by explaining how the reduction in tardies supports the paragraph's claim about later school start times improving student learning through increased sleep and reduced tardiness. Choice A clarifies this by connecting the drop in tardies to more consistent student arrival, which preserves instructional time and directly ties into learning gains from better-rested students. It emphasizes the significance of the evidence, showing not just that tardies decreased, but why this matters for the overall argument on learning improvement. By highlighting the protection of instructional time, the revision makes the evidence's relevance to the claim explicit and analytical. In contrast, choice B fails as a distractor because it merely restates the evidence without any interpretation or connection to the claim. A transferable writing principle is that effective commentary interprets evidence to demonstrate its direct support for the claim, a skill essential for crafting strong body paragraphs in AP English Language argumentative essays.

Question 9

A community advocate argues: "The county should expand its public transit routes because transportation access increases employment opportunities." In the paragraph, the writer offers evidence: "After a new bus line opened connecting two low-income neighborhoods to an industrial park, the transit agency reported a 22% increase in ridership during early-morning shift hours." The commentary that follows is weak: "This shows more people rode the bus in the morning."

Which revision of the bolded commentary would best explain how the evidence supports the claim?​

  1. This suggests the route is being used specifically for commuting to jobs with early shifts, implying that when transit reaches employment centers, residents can actually take or keep those jobs—supporting the argument that access expands opportunity. (correct answer)
  2. This proves that industrial parks are the most important part of any county.
  3. This shows the transit agency reported ridership and that riders traveled in the morning.
  4. This means the county should raise bus fares to pay for more routes.
Explanation: This question evaluates the writer's ability to interpret ridership data to support their claim about transit access increasing employment opportunities. Choice A effectively connects the evidence: the specific timing (early-morning shifts) and destination (industrial park) suggest people are using the route to commute to jobs, implying that transit access enables residents to take or keep employment—directly supporting the opportunity claim. Choice B makes an irrelevant value judgment. Choice C restates facts without interpretation. Choice D suggests an unrelated policy. The principle is that commentary must explain what the evidence implies about your claim.

Question 10

In a school board meeting op-ed, a student argues that the district should adopt a later high school start time. In one body paragraph, the writer claims: "Moving first period later would improve learning because students would arrive more rested and ready to focus." The paragraph includes this evidence: "After Seattle Public Schools delayed start times in 2016, researchers reported that students slept about 34 minutes more per night and median grades increased by 4.5% in core classes." The writer's commentary is weak: "This shows that students slept more and their grades went up."

Which revision of the bolded commentary would best explain the significance of the evidence in support of the paragraph's claim?​

  1. This matters because the Seattle data links the policy change (later starts) to both increased sleep and measurable academic gains, suggesting that additional rest can translate into better classroom performance rather than just feeling less tired. (correct answer)
  2. Seattle changed its start time in 2016, and researchers studied what happened to students afterward.
  3. The study proves that every school will see the exact same grade increase if it changes the schedule.
  4. Even if grades rise, schools should focus on sports schedules instead of academics when setting start times.
Explanation: This question tests the writer's ability to integrate evidence with commentary by explaining why the evidence matters to the claim about later start times improving learning. Choice A effectively connects the Seattle data to the claim by showing how increased sleep translates into measurable academic gains, not just reduced tiredness—directly supporting the idea that later starts improve learning. Choice B merely restates facts without interpretation. Choice C overgeneralizes beyond what the evidence supports. Choice D contradicts the argument's focus on academics. The key writing principle is that commentary must explain how evidence proves your specific claim, not just restate what the evidence says.

Question 11

A student is revising a paragraph arguing that employers should adopt a four-day workweek. The paragraph's claim is: A four-day workweek can maintain productivity while reducing burnout.

Evidence in the paragraph: In a six-month pilot involving 33 companies, an independent evaluation reported that revenue stayed roughly the same while employee-reported burnout scores (on a 1–10 scale) dropped from an average of 6.8 to 4.9.

The writer's commentary is "Burnout scores dropped, and revenue stayed the same."

Which sentence would most effectively replace the bolded commentary to connect the evidence to the paragraph's claim?

  1. Because companies maintained revenue while workers reported substantially less burnout, the pilot suggests shorter schedules can preserve output without demanding the same level of strain from employees. (correct answer)
  2. The evaluation measured revenue and burnout scores during a six-month pilot of 33 companies.
  3. This means every workplace should immediately switch to a four-day week, regardless of industry or staffing needs.
  4. Burnout is a serious issue that affects many people in many different jobs.
Explanation: The rhetorical goal involves integrating evidence with commentary to demonstrate how a four-day workweek maintains productivity while alleviating burnout, as per the paragraph's claim. Choice A clarifies this by noting that steady revenue alongside reduced burnout indicates the schedule preserves output without excessive employee strain, directly linking the data to the claim's dual benefits. It interprets the evidence to show practical implications, emphasizing sustainability for workers. This revision provides analytical depth, explaining why the unchanged revenue is significant in the context of lower burnout. Choice B fails as a distractor by merely describing the study's methods without connecting to the claim's argument. A transferable writing principle is to use commentary for interpreting evidence's role in advancing the claim, which is assessed in the essay portions of the AP English Language exam.

Question 12

A student writes an argumentative essay urging the cafeteria to add more plant-based options. The paragraph's claim is: "Offering appealing plant-based meals can reduce food waste in school cafeterias." The evidence reads: "In a 2019 pilot in a Massachusetts district, schools that renamed vegetable-based entrées with more descriptive titles (e.g., 'zesty chili-lime beans') reported 14% fewer uneaten servings thrown away on those days." The writer's commentary is weak: "This shows that descriptive titles led to fewer servings being thrown away."

Which revision of the bolded commentary would best explain why the evidence supports the claim?​

  1. This suggests that when plant-based dishes are marketed in ways that make them sound appetizing, more students actually choose and finish them—so expanding these options could lower waste rather than add new items students ignore. (correct answer)
  2. This means all students dislike vegetables unless they are forced to eat them.
  3. This proves that schools should spend more money on professional branding agencies for every menu item.
  4. This shows that the pilot happened in Massachusetts and included renamed entrées.
Explanation: This question evaluates the writer's ability to explain how evidence about renamed menu items supports the claim about reducing food waste through plant-based options. Choice A effectively connects the dots: when plant-based dishes are marketed appealingly (through descriptive names), students choose and finish them more often, which means expanding such options could reduce waste rather than create ignored items. Choice B overgeneralizes about all students. Choice C makes an irrelevant leap to professional branding. Choice D merely restates facts without interpretation. The writing principle is that commentary must show the logical connection between evidence and claim, not just repeat information.

Question 13

Read the body paragraph from an argument advocating for free community college.

Claim: Making community college tuition-free strengthens local economies by increasing credential completion.

Paragraph: After one county introduced a "last-dollar" scholarship covering tuition, enrollment at its community college rose 11% in the first year. Yet the college's own dashboard shows certificate completion rates stayed nearly flat: 28% before the program and 29% after. Therefore, the scholarship strengthened the local economy by increasing credential completion.

Why does the evidence fail to fully support the claim as written?

  1. Because the evidence discusses enrollment and completion at a community college, which are unrelated to the economy.
  2. Because the evidence shows enrollment increased but completion barely changed, the paragraph does not demonstrate the specific mechanism the claim relies on—increased credential completion. (correct answer)
  3. Because last-dollar scholarships are always ineffective, the argument is automatically invalid.
  4. Because the completion rate increased from 28% to 29%, the scholarship clearly caused a major jump in credentials.
Explanation: This question tests understanding of how evidence can fail to support a claim when the mechanism isn't demonstrated. The correct answer (B) identifies that while enrollment increased, "completion barely changed," meaning the evidence doesn't show the "specific mechanism the claim relies on—increased credential completion." This explanation recognizes that the claim promises economic benefits through more credentials, but the evidence shows only more enrollment without corresponding completion gains. Choice D misinterprets a 1% change as "major," while A incorrectly suggests community colleges are unrelated to economics. The key principle is that evidence must demonstrate the specific causal mechanism your claim proposes, not just show that something changed.

Question 14

A student is writing a body paragraph arguing that schools should provide free breakfast to all students. The paragraph's claim is: Universal breakfast reduces stigma and increases participation, which can improve students' readiness to learn.

Evidence included: After one middle school switched from "free breakfast for eligible students" to "breakfast for all," participation increased from 38% of students to 71% in two months.

The commentary after the evidence is "More students ate breakfast after the change."

Which revision of the bolded commentary would best connect the evidence to the claim?

  1. The sharp participation jump suggests that making breakfast universal removes barriers—like eligibility paperwork or fear of being singled out—so more students start the day fed and better prepared to focus in class. (correct answer)
  2. Participation increased from 38% to 71% after the school switched to breakfast for all.
  3. This proves that breakfast is the only factor that determines whether students learn anything in school.
  4. Students like food, and schools should offer more menu choices at breakfast.
Explanation: The rhetorical goal involves integrating evidence with commentary to show how universal breakfast boosts participation and reduces stigma, aiding students' learning readiness as per the claim. Choice A explains this by attributing the participation surge to removed barriers like paperwork or stigma, linking it to better-fed students and improved focus. It highlights the evidence's significance in demonstrating accessibility's role in higher engagement. This revision provides analytical connection, showing the change's direct impact on the claim's goals. Choice B fails as a distractor by restating percentages without interpreting their meaning for the argument. A key transferable principle is using commentary to connect evidence meaningfully to the claim, which is critical for AP English Language argumentative essays.

Question 15

Read the body paragraph from an editorial about smartphone restrictions in middle schools.

Claim: Restricting phone access during class improves learning by reducing distraction.

Paragraph: After Brookside Middle required phones to be stored in locked pouches during instructional time, the school reported that office referrals for "off-task behavior" dropped by 26% over the next quarter. However, the same report notes that the school also introduced a new behavior-reward system that quarter. This proves the phone pouches improved learning.

Which sentence would most effectively be added after the evidence to connect it to the claim while addressing the competing explanation?

Add after: "However, the same report notes that the school also introduced a new behavior-reward system that quarter." [INSERT SENTENCE HERE]

  1. Off-task behavior dropped by 26%, which is a large number for a middle school.
  2. Because two interventions changed at once, the referral drop cannot be attributed solely to phone pouches; the argument needs classroom-level data (such as time-on-task observations or assessment trends) to show reduced distraction is the driver of improved learning. (correct answer)
  3. This shows that phones are harmful and should be banned for all teenagers everywhere, even outside of school.
  4. The reward system is the main reason students learned more, not the pouches.
Explanation: This question assesses the ability to craft commentary that addresses competing explanations when multiple interventions occur simultaneously. The correct answer (B) acknowledges that "because two interventions changed at once, the referral drop cannot be attributed solely to phone pouches" and suggests what additional evidence would be needed—"classroom-level data" showing reduced distraction drives learning improvement. This sophisticated commentary recognizes the attribution problem while maintaining focus on the original claim about learning through reduced distraction. Choice D dismisses the pouches entirely without evidence, while A ignores the competing explanation. The writing principle is that when evidence has multiple possible explanations, effective commentary should acknowledge this complexity while explaining what additional evidence would strengthen the argument.

Question 16

Read the body paragraph from an argument supporting municipal tree-planting.

Claim: Planting street trees is a cost-effective way to reduce summer heat exposure in low-income neighborhoods.

Paragraph: The city's pilot planted 300 trees along three bus corridors in the hottest census tracts. A follow-up measurement found midday sidewalk temperatures on shaded blocks averaged 4°F cooler than nearby unshaded blocks. The pilot's total cost was $210,000, including watering contracts for the first two years. This shows shaded blocks were cooler and the pilot cost $210,000.

Which revision of the bolded commentary best explains how the cost and temperature data support the claim?

  1. This is significant because a measurable 4°F reduction indicates trees directly lower heat exposure where residents walk and wait for transit, and the stated total cost allows readers to evaluate cost-effectiveness against other heat-mitigation options rather than relying on vague promises. (correct answer)
  2. This is significant because $210,000 is a lot of money and trees are nice to look at.
  3. This proves the city should stop funding air conditioning assistance programs entirely.
  4. This shows the temperature was 4°F cooler on shaded blocks and the cost was $210,000.
Explanation: This question evaluates how to write commentary that explains both effectiveness and cost-efficiency when making policy arguments. The correct answer (A) interprets the 4°F reduction as evidence that trees "directly lower heat exposure where residents walk and wait for transit" while noting the cost disclosure "allows readers to evaluate cost-effectiveness against other heat-mitigation options." This commentary connects specific temperature data to lived experience while enabling comparative analysis. Choice D merely restates facts without interpretation, while B offers vague observations about money and aesthetics. The key principle is that policy arguments require commentary that explains both the practical impact of evidence and how it enables comparison with alternatives.

Question 17

What is the main flaw in 'The study says so; therefore, the claim is true'?

  1. It ignores counterevidence.
  2. It equates source with proof. (correct answer)
  3. It fails to cite the study.
  4. It summarizes the evidence.
Explanation: The argument treats the mere existence of a study as sufficient verification, but a source can be flawed, biased, or misreported; citing it doesn't by itself prove the claim. The tempting wrong answer is ignoring counterevidence, but the core flaw is confusing the source with actual proof.

Question 18

Which best describes effective evidence integration?

  1. Put evidence before the claim.
  2. Let evidence speak for itself.
  3. Weave evidence with analysis. (correct answer)
  4. Keep evidence and claim apart.
Explanation: Effective integration means connecting each piece of evidence to your own reasoning, so the reader sees exactly how the evidence supports the claim. The tempting mistake is letting evidence speak for itself, because facts don't explain their own significance. You need analysis to draw out the point.

Question 19

Which comment best connects a statistic to a claim?

  1. It shows a need for change. (correct answer)
  2. The source is reputable.
  3. The data are accurate.
  4. The sample size is large.
Explanation: The best comment connects a statistic to a claim by stating the implication: it shows a need for change. Accuracy, the tempting wrong choice, only tells you the statistic can be trusted; it does not explain what the statistic means for the claim being made.

Question 20

Which best joins two statistics with commentary?

  1. The first one is accurate.
  2. Sources often disagree.
  3. The numbers are very high.
  4. They reveal a shared trend. (correct answer)
Explanation: To join two statistics, you need a statement that connects them, not just evaluates one or both. They reveal a shared trend points out a relationship between the data, making it commentary that ties the two together. The tempting wrong answer, The numbers are very high, only describes magnitude and does not connect the statistics.
