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?
The CEO said the trial succeeded because employees were more productive, working, fewer hours.
The CEO said the trial succeeded because employees were more productive, which worked fewer hours.
The CEO said the trial succeeded because employees were more productive while working fewer hours.
The CEO said the trial succeeded because employees were more productive, and fewer hours were worked.
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.
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?
After the platform noticed users paused on angry clips, it promoted them, which changed them.
After the platform noticed users paused on angry clips, promotion occurred, which changed the tone of the app.
After the platform noticed users paused on angry clips, it promoted those clips, changing the tone of the app.
After noticing users paused on angry clips, the platform promoted them, 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.
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?
Planting trees can cool the neighborhood, lowering temperatures, on streets in summer.
Planting trees can cool the neighborhood, which lowers temperatures on streets in summer.
Planting trees can cool the neighborhood by lowering summer street temperatures.
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.
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?
To reduce contamination, the city mailed residents, listing common mistakes, a guide.
To reduce contamination, the city mailed residents a guide that listed common mistakes.
To reduce contamination, the city mailed residents a guide, and common mistakes were listed.
To reduce contamination, mailing residents a guide, the city listed common mistakes.
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.
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?
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.
By the end of the week, the schedule has stolen thirty minutes from students, enough time to finish a chapter sitting in the library.
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.
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.
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.
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?
Because the plans are marketed to young shoppers, the debt, feeling temporary, is appealing.
Because the plans, marketed to young shoppers, the debt feels temporary.
Because the plans are marketed to young shoppers, the debt feels temporary to them.
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.
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?
After the county texted reminders to patients, missed appointments fell, so the county expanded the reminder program.
After texting reminders to patients, missed appointments fell, which expanded the county.
After texting reminders to patients, missed appointments fell, which the county expanded quickly.
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.
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?
When teachers assign research projects, relying on websites can mislead students often.
When teachers assign research projects, websites are often relied on, which can mislead students.
When teachers assign research projects, they often rely on websites, which can mislead students.
When teachers assign research projects, students often rely on websites that can mislead them.
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.
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?
Before the first clinic opened, the county emailed reminders to residents, reaching thousands, in Spanish and English.
Before the first clinic opened, the county emailed bilingual reminders to residents, reaching thousands.
Before the first clinic opened, the county emailed reminders to residents, which were in Spanish and English, reaching thousands.
Before the first clinic opened, the county emailed reminders to residents in Spanish and English, reaching the reminders’ 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.
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?
The association asked the city to ticket businesses that regularly violate the ordinance, not businesses that comply with it.
The association asked the city to ticket businesses that violate the ordinance regularly, not the ones that comply.
The association asked the city to ticket businesses that violate the ordinance, not regularly, but consistently.
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.
