Read the following embedded passage and answer the question.
A library director contends that eliminating late fees increases the return of materials and expands access without encouraging irresponsibility. In the six months after fees were removed, the number of patrons with blocked accounts dropped from 3,100 to 900, and overall circulation rose 18%. Staff also tracked returns and found that the median time an overdue item remained out fell from 12 days to 7 days. Some residents argue that people will keep books longer if there is no penalty, but the director points to the shorter median overdue period as evidence that patrons are returning items sooner, not later.
The author uses this evidence to suggest that…
the median time an overdue item remained out fell from 12 days to 7 days
removing fees did not reduce accountability, since items are being returned more quickly on average, supporting the claim that access can expand without worsening return behavior
the median overdue time fell from 12 days to 7 days, which means the median number changed
the library’s collection must have shrunk, because fewer days overdue means fewer items exist to borrow
all patrons now return every item on time, showing that late fees were the only reason materials were ever overdue
Explanation
This question asks you to explain how evidence supports a claim about eliminating library late fees. The evidence that median overdue time fell from 12 to 7 days directly counters the concern that removing fees would encourage irresponsibility. Instead of keeping materials longer without penalties, patrons are actually returning items more quickly. This supports the director's claim that fees can be eliminated without negative consequences to return behavior, while actually expanding access (as shown by fewer blocked accounts). Choice B overstates the evidence by claiming all items are returned on time, while C makes an illogical connection. When analyzing evidence about policy changes, look for how the data addresses specific concerns raised by critics.
Read the following embedded passage and answer the question.
A neighborhood association president claims that planting street trees is a cost-effective way to reduce summer heat stress. She points to a three-year initiative that planted 220 trees along two major corridors. During the most recent July, surface temperature readings on shaded sidewalks averaged 9°F cooler at noon than readings on adjacent unshaded blocks, and the local clinic reported a 14% decrease in heat-related visits from residents living within three blocks of the corridors compared with the prior July. Opponents argue that the clinic numbers could reflect other factors, but the president emphasizes that the temperature difference is a direct measurement of the trees’ immediate impact.
The author uses this evidence to suggest that…
surface temperature readings on shaded sidewalks averaged 9°F cooler at noon than readings on adjacent unshaded blocks
trees measurably lower the heat people experience in daily outdoor spaces, supporting the claim that they can mitigate heat stress efficiently
trees eliminate all heat-related illness, proving that shade alone fully solves public health problems in summer
shaded sidewalks were 9°F cooler than unshaded ones, meaning there was a temperature difference between them
the corridors received more funding for clinics, which is why shaded sidewalks were cooler
Explanation
This question asks you to explain how evidence supports a claim about street trees reducing heat stress. The evidence that shaded sidewalks were 9°F cooler provides direct, measurable proof that trees lower temperatures in outdoor spaces where people walk and wait. This temperature reduction supports the president's claim that trees are a cost-effective way to reduce heat stress—the physical cooling effect is immediate and substantial. The connection to reduced heat-related clinic visits strengthens this support. Choice B overstates the impact by claiming total elimination of illness, while C invents an unrelated funding explanation. When analyzing environmental interventions, focus on direct measurements that demonstrate the claimed effect.
Read the following embedded passage and answer the question.
A city council member argues that the new “Open Streets” program—closing three downtown blocks to cars on Saturdays—has strengthened local businesses more than it has inconvenienced drivers. She notes that during the first eight Saturdays, sales-tax receipts from those blocks rose 12% compared with the same period last year, while parking-garage entries within a half-mile fell 4%. She adds that the transit agency reported a 9% increase in weekend ridership on routes serving downtown, and that the police department recorded no increase in emergency response times in the area. Critics counter that some shoppers may simply be buying on Saturdays instead of other days, but the council member responds that the receipts are year-over-year, not week-to-week.
The author uses this evidence to suggest that…
sales-tax receipts from those blocks rose 12% compared with the same period last year
sales-tax receipts rose 12% compared with last year, meaning the receipts were higher than before
the program’s car restrictions likely increased commercial activity in the affected area rather than merely shifting it to a different day, supporting her claim that businesses benefited overall
the program reduced parking demand so drastically that downtown drivers were effectively eliminated, which is why businesses improved
all businesses citywide experienced the same increase in revenue, proving that the program caused a general economic boom
Explanation
This question asks you to explain how evidence supports a claim about the benefits of the Open Streets program. The evidence shows sales-tax receipts rose 12% compared to the same period last year, which directly supports the council member's claim that businesses have been strengthened. The year-over-year comparison is crucial because it addresses the critics' concern about sales merely shifting between days—if people were just buying on Saturdays instead of other days, the yearly comparison wouldn't show an increase. Choice B incorrectly overgeneralizes to all businesses citywide, while C makes an unsupported claim about eliminating drivers. When analyzing how evidence supports a claim, focus on the logical connection between what the data shows and what the author argues, paying attention to how the evidence addresses potential counterarguments.
Read the following embedded passage and answer the question.
A public health columnist claims that small design changes in cafeterias can meaningfully improve nutrition without banning foods. In a county pilot, cafeterias moved fruit to the front of the serving line and placed water at eye level. Over ten school days, students selected fruit in 41% of lunches, up from 26% before the change, while sales of desserts declined 8%. The columnist also notes that no menu items were removed, and that students could still choose dessert if they wanted. Critics argue that students will compensate after school, but the columnist suggests that repeated small choices can accumulate.
The author uses this evidence to suggest that…
students selected fruit in 41% of lunches, up from 26% before the change
fruit selection rose to 41% from 26%, meaning more fruit was chosen than before
the county’s fruit suppliers raised prices, which explains why students chose fruit more often
altering the environment can nudge students toward healthier choices without restricting options, supporting the claim that design can improve nutrition
students stopped eating dessert entirely, demonstrating that the pilot effectively banned unhealthy foods
Explanation
This question asks you to explain how evidence supports a claim about cafeteria design improving nutrition. The evidence that fruit selection rose from 26% to 41% demonstrates that simply changing placement can influence student choices without restricting options. This supports the columnist's claim that small design changes can meaningfully improve nutrition—students chose healthier options more frequently when fruit was more accessible and visible. The fact that no items were removed shows this isn't about restriction but about nudging behavior. Choice B incorrectly claims desserts were banned, while C invents an unsupported price explanation. When analyzing behavioral interventions, focus on how environmental changes can influence choices while preserving autonomy.
Read the following embedded passage and answer the question.
A museum educator argues that free admission days can broaden participation without diminishing visitor engagement. She cites a year in which the museum offered free entry on the first Sunday of each month. On those Sundays, the share of visitors from ZIP codes with median incomes below the city average rose from 18% to 33%, and the average time spent in galleries held steady at about 74 minutes, matching paid-admission Sundays. Some donors worry that free days attract “casual” visitors who rush through, but the educator maintains that stable visit length suggests comparable engagement.
The evidence supports the author's claim by…
the share of visitors from ZIP codes with median incomes below the city average rose from 18% to 33%
noting that the share rose from 18% to 33%, which means the percentage changed over time
proving that the museum’s overall revenue increased on free days, which is the best measure of engagement
indicating that visitors stayed longer in galleries, which directly demonstrates higher income levels among attendees
showing that removing a price barrier brings in more visitors from less affluent areas, supporting the claim that free days broaden participation
Explanation
This question requires explaining how evidence supports a claim about free museum days broadening participation. The evidence that visitors from lower-income ZIP codes increased from 18% to 33% directly demonstrates that removing the price barrier attracted a more economically diverse audience. This supports the educator's claim that free days broaden participation—the museum is reaching populations who were underrepresented during paid admission. The stable visit duration shows these new visitors are equally engaged. Choice B incorrectly focuses on revenue rather than participation, while C misconnects visit length to income. When evaluating access initiatives, examine how demographic changes reflect the stated goal of broadening participation.
Read the following embedded passage and answer the question.
A workplace analyst argues that remote work can increase productivity when paired with clear expectations. She describes a customer-support team that shifted to remote work three days a week and adopted standardized response templates. After two months, average first-response time to customer tickets fell from 3.8 hours to 2.1 hours, while customer satisfaction scores rose from 4.2 to 4.5 (out of 5). The analyst notes that managers also reported fewer “status meetings,” but insisted on daily written check-ins. Some executives claim the improvement must be temporary, yet the analyst points out that the metrics improved after the new routines stabilized.
The evidence supports the author's claim by…
average first-response time to customer tickets fell from 3.8 hours to 2.1 hours
indicating that customers filed fewer complaints about pricing, which is the main driver of satisfaction in support teams
demonstrating that employees worked fewer hours overall, which proves remote work is always better for work-life balance
repeating that first-response time fell from 3.8 to 2.1 hours, which means responses were quicker
showing faster service after the shift and new procedures, implying that remote work with structure can improve output rather than slow it down
Explanation
This question requires explaining how evidence supports a claim about remote work increasing productivity. The evidence that first-response time fell from 3.8 to 2.1 hours demonstrates faster service, directly supporting the analyst's claim that remote work can increase productivity when paired with clear expectations (like standardized templates and daily check-ins). This improvement in a key performance metric shows that the structured remote arrangement enhanced rather than hindered output. Choice B incorrectly focuses on hours worked rather than productivity, while C misidentifies the metric. When evaluating workplace changes, examine how performance metrics relate to the specific claim about productivity.
Read the following embedded passage and answer the question.
A high school principal claims that later start times improve learning more than they disrupt after-school activities. After shifting the first bell from 7:20 to 8:10, the school found that first-period tardies dropped from an average of 38 per day to 14 per day, and the nurse logged 22% fewer visits for headaches and fatigue during morning classes. The principal also reports that the percentage of students earning D’s or F’s in first-period courses fell from 19% to 11%, while coaches report only minor scheduling adjustments. A few parents complain that students are simply staying up later, but the principal argues that the reduction in fatigue-related nurse visits suggests otherwise.
The evidence supports the author's claim by…
first-period tardies dropped from an average of 38 per day to 14 per day
showing that students are arriving more consistently when the day begins later, implying the schedule change reduces barriers to attendance and supports improved learning conditions
restating that tardies decreased, which indicates there were fewer tardy students
proving that every student now gets more sleep, which guarantees higher test scores in all subjects
demonstrating that after-school sports became easier to schedule, which is the primary goal of delaying the start time
Explanation
This question requires explaining how evidence supports a claim about later school start times improving learning. The evidence that first-period tardies dropped from 38 to 14 per day supports the principal's claim by showing students are arriving more consistently when school starts later. This improved attendance creates better learning conditions—students who are present can actually benefit from instruction. The connection between reduced tardiness and improved learning is logical: students must be present to learn effectively. Choice B makes an unsupported leap to guaranteed test scores, while C misidentifies the primary goal. When examining how evidence supports educational claims, consider how the data connects to the learning environment and student readiness to learn.
Read the following embedded passage and answer the question.
A technology columnist argues that requiring two-factor authentication (2FA) for school email accounts improves security without significantly increasing help-desk burden. After a district enabled 2FA for all staff, successful account takeovers dropped from 27 incidents in the prior semester to 3 incidents, while help-desk tickets related to login issues rose from 410 to 455 during the first month and then returned to baseline the next month. The columnist acknowledges the initial spike in tickets but argues that the long-term tradeoff is favorable because compromised accounts can expose student data and trigger costly recovery work.
The evidence supports the author's claim by…
successful account takeovers dropped from 27 incidents in the prior semester to 3 incidents
stating that takeovers dropped from 27 to 3, which means there were fewer incidents
demonstrating a substantial reduction in a key security failure, supporting the claim that 2FA meaningfully improves protection even if it causes minor short‑term friction
indicating that staff members forgot their passwords more often, which is why account takeovers decreased
showing that the district eliminated all cyber threats permanently, proving that 2FA makes any further security measures unnecessary
Explanation
This question requires explaining how evidence supports a claim about two-factor authentication improving security without excessive burden. The evidence that account takeovers dropped from 27 to 3 incidents demonstrates a dramatic improvement in security—a nearly 90% reduction in successful breaches. This substantial reduction supports the columnist's claim that 2FA meaningfully improves protection, justifying the temporary increase in help-desk tickets. The return to baseline ticket levels after one month shows the burden was indeed temporary. Choice B overstates by claiming permanent elimination of all threats, while C creates an illogical connection. When evaluating security measures, weigh the magnitude of security improvements against temporary implementation challenges.
Read the following embedded passage and answer the question.
An editor argues that shortening news articles does not necessarily make them more readable. She cites analytics from her publication showing that after a major “brevity initiative,” average article length fell by 35% but the share of readers who reached the end dropped from 54% to 46%. She also notes that reader feedback increasingly complained that stories felt “context-free,” and reporters reported spending more time writing headlines to compensate for missing explanation. The editor concedes that some pieces benefit from trimming, but she claims that cutting context can force readers to work harder to infer meaning, which may reduce completion. Her claim is that readability depends on clarity and structure, not just fewer words.
The evidence supports the author’s claim by…
showing that shorter articles automatically confuse readers because any reduction in length removes all necessary context
proving that headlines are the only part of an article that matters because reporters spent more time writing them
indicating that despite shorter length, completion fell and complaints rose, implying that brevity alone may harm clarity and thus readability
repeating that article length fell by 35% and end-of-article reach fell from 54% to 46%
Explanation
This question asks you to explain how evidence supports a claim about shorter articles not necessarily being more readable. The editor provides evidence that despite a 35% reduction in article length, reader completion rates actually dropped from 54% to 46%, and complaints about "context-free" stories increased. This counterintuitive result—shorter articles being completed less often—supports the claim that brevity alone may harm clarity and thus readability. Choice B correctly identifies how this evidence implies that cutting context forces readers to work harder, reducing completion. Choice D fails by merely listing the statistics without explaining the paradox of shorter articles performing worse. The key insight is recognizing how evidence of unintended consequences can support claims that challenge assumptions about simplicity and accessibility.
Read the following embedded passage and answer the question.
A superintendent claims that switching to a later high-school start time improved learning. In her memo, she points out that after the schedule change, first-period tardiness fell from 18% to 7%, and teachers reported fewer students “sleeping in class.” She also cites district data showing that the biggest gains in course pass rates occurred in ninth grade, the cohort that previously had the earliest bus pickups. She acknowledges that the district also updated its math curriculum that year, but she argues that a curriculum change would not so neatly match improvements in the specific period most affected by the bell schedule. Her central claim is that the later start time was a primary driver of the improved academic outcomes.
The evidence supports the author’s claim by…
suggesting that all students in every grade learned more because any decrease in tardiness guarantees higher test scores
showing that reduced tardiness and grade-level gains align with the timing change in a way that implies the schedule shift contributed to learning improvements
listing numerical changes in tardiness and ninth-grade pass rates without linking them to why the start time matters
proving that curriculum updates cannot affect pass rates because instructional materials never influence student performance
Explanation
This question asks you to explain how evidence supports a claim about later school start times improving learning. The superintendent provides evidence that directly connects to the schedule change: tardiness dropped dramatically in first period (when the change would have the most impact), and the biggest academic gains occurred in ninth grade (the group previously affected by the earliest bus pickups). This targeted pattern of improvement—occurring exactly where the schedule change would theoretically help most—creates a logical link between the intervention and the outcomes. Choice A correctly identifies how this alignment implies the schedule shift contributed to improvements. Choice D fails because it merely lists the statistics without explaining the connection, missing how the evidence specifically targets areas most affected by the change. When analyzing evidence-claim relationships, look for patterns that match the expected effects of the proposed cause.
