Question 1

The city council approved a proposal that shortened curbside parking from two hours to thirty minutes and created an annual permit fee for delivery vehicles. A reporter wrote, "These things upset several downtown merchants."

Which replacement for "These things" most clearly identifies the causes of the merchants' reaction?

  1. The council's discussion and final vote
  2. The downtown parking and delivery systems
  3. The shorter parking limit and new permit fee (correct answer)
  4. The proposal's effects on local transportation
Explanation: When editing for clarity, your job is to ensure that vague references are replaced with specific, accurate language — especially when a pronoun or generic phrase like "these things" could confuse the reader about what's actually being discussed. Here, the passage describes two concrete actions taken by the city council: shortening parking from two hours to thirty minutes, and creating an annual permit fee for delivery vehicles. The merchants were upset by these specific measures. So the ideal replacement for "These things" should name exactly those two causes — nothing more, nothing less. Choice C does precisely that: "the shorter parking limit and new permit fee" maps directly onto the two policy changes described, giving the reader an immediate, accurate picture of why merchants were frustrated. That's your correct answer. Choice A ("the council's discussion and final vote") focuses on the process of decision-making, not the actual policies that affected merchants. Merchants wouldn't be upset about a vote in the abstract — they'd be upset about what the vote produced. Choice B ("the downtown parking and delivery systems") is far too broad. It refers to existing infrastructure rather than the specific new restrictions, which muddies the cause-and-effect relationship the sentence is trying to establish. Choice D ("the proposal's effects on local transportation") is vague in a different way — it gestures toward consequences without specifying what they are, leaving the reader no clearer than "these things" did. A useful rule of thumb: when replacing a vague reference, count the specific causes mentioned in the passage and make sure your replacement accounts for each one precisely — no more, no fewer.

Question 2

At sites upstream and downstream from a paper mill, a research team collected water samples and recorded the water temperature. Laboratory testing had not yet begun when a team member wrote, "The researchers studied various things at both sites."

Which revision is most precise without claiming that the team completed work not described in the passage?

  1. The researchers analyzed contaminants and identified their sources at both sites.
  2. The researchers compared pollution levels above and below the paper mill.
  3. The researchers investigated several environmental conditions near the paper mill.
  4. The researchers collected water samples and recorded water temperature at both sites. (correct answer)
Explanation: When a question asks you to revise a vague sentence to be more precise without overstating, you're being tested on two simultaneous constraints: specificity and accuracy. The revision must say more than the vague original, but it cannot introduce details the passage never established. The passage tells you exactly two things the team did: collected water samples and recorded water temperature — both at upstream and downstream sites. Option D mirrors this perfectly, replacing "various things" with the actual actions described, making it both more precise and completely faithful to the passage. That's your answer. Now look at why the others fail. Option A says the researchers "analyzed contaminants and identified their sources" — but the passage explicitly states that laboratory testing had not yet begun. This revision invents completed work that never happened, violating the accuracy constraint. Option B claims the team "compared pollution levels," but the passage never mentions pollution levels being compared; it describes collection and recording, not analysis or comparison. Option C is subtler — "investigated several environmental conditions" sounds reasonable, but "environmental conditions" is still vague (no more specific than "various things"), and "investigated" implies a depth of analysis the passage doesn't support. Your strategy here: treat the passage as a contract. Every word in your revision must be cashed out by something explicitly stated in the passage — no more, no less. When you see phrases like "without claiming work not described," that's your signal to cross-check each option against what the text actually says happened, not what seems plausible.

Question 3

A transit survey asked commuters to rank three considerations: fare cost, service frequency, and seat availability. The rankings varied substantially among respondents. A summary states, "People cared about different things."

Which revision most precisely summarizes the survey result without asserting a preference the data do not establish?

  1. Transit users expressed different opinions about the overall quality of service.
  2. Commuters disagreed mainly about ticket prices and average travel speed.
  3. Riders valued comfortable seating more highly than frequent transit service.
  4. Commuters ranked fare cost, service frequency, and seat availability differently. (correct answer)
Explanation: When a question asks you to "precisely summarize" a data source, your job is to match the summary exactly to what the data show — nothing more, nothing less. The key skill being tested here is fidelity to evidence: avoiding distortions like unsupported additions, substitutions of different details, or conclusions the data never reached. The passage tells you three specific things were ranked — fare cost, service frequency, and seat availability — and that rankings varied among respondents. That's it. Answer D captures this perfectly: it names all three correct considerations and says only that commuters ranked them differently, which is exactly what "rankings varied substantially" means. No assumptions, no additions. Here's where the distractors go wrong. A shifts the topic entirely — "overall quality of service" was never measured, so this substitutes a broader, unrelated judgment for the specific ranking data. B introduces "ticket prices" (a reasonable synonym for fare cost) but invents "average travel speed," which was never one of the three ranked considerations; this is a fabrication error. C commits the most serious mistake: it asserts that riders preferred seating over frequency, but the data only show that rankings varied — it never establishes which consideration ranked highest overall. Drawing a preference conclusion from variation data is a classic overstep. The strategy to remember: when evaluating summaries, ask yourself two questions — Does this change any details from the source? and Does this go beyond what the source concludes? If either answer is yes, the choice is wrong. Precision means staying inside the boundaries of the data, not inferring beyond them.

Question 4

An internal audit found that several invoices had been approved even though the required supervisor signatures were missing. A draft summary begins, "One thing the audit revealed was that several invoices had signature issues."

Which revision eliminates vague and empty wording while preserving the audit's level of certainty?

  1. The audit revealed that several approved invoices lacked required supervisor signatures. (correct answer)
  2. The auditors proved that employees deliberately omitted signatures from several invoices.
  3. The audit discussed problems involving the approval of several company invoices.
  4. Several approved invoices apparently had some kind of signature-related problem.
Explanation: When revising for clarity and precision, your goal is to match the original meaning exactly — no more, no less. Ask yourself: does this revision say what the source material says, using specific language, without adding unsupported claims or retreating into vagueness? The original passage tells us two concrete things: invoices were approved, and required supervisor signatures were missing. A strong revision captures both facts directly. Option A does exactly this — "several approved invoices lacked required supervisor signatures" names the specific problem (missing required signatures) and preserves the audit's finding without inflating or deflating it. This is why A is the correct answer. Option B oversteps the source material. The audit found missing signatures, but it did not establish that employees deliberately omitted them. Introducing intent ("deliberately") adds an unsupported claim, which misrepresents the audit's level of certainty — a serious error in professional and academic writing. Option C replaces specific details with vague abstractions. "Discussed problems involving the approval of several company invoices" tells the reader almost nothing useful. Words like "discussed" and "problems" drain the sentence of the precise information the audit actually uncovered. Option D is similarly evasive. "Apparently had some kind of signature-related problem" uses hedging language ("apparently," "some kind of") that suggests uncertainty where the audit was actually clear. This is the opposite of good revision — it introduces doubt rather than clarity. A useful rule of thumb: when revising, watch for words like apparently, some kind of, issues, and problems — these are often signals of empty or vague phrasing. Equally, watch for unsupported additions like intent or motive that go beyond what a source actually establishes.

Question 5

After the final scene, the stage crew rolled two movable platforms into the scenery bay and carried six folding chairs into the furniture storeroom. The production log states, "The crew moved stuff after the performance."

Which revision provides the most precise account of what the crew moved and where the items went?

  1. The crew moved the stage equipment and furniture into the appropriate backstage storage areas.
  2. The crew stored two movable platforms in the scenery bay and six folding chairs in the furniture storeroom. (correct answer)
  3. The crew carried the scenery and props away from the stage and into the storage rooms.
  4. The crew returned all movable equipment and seating to the theater's designated storage facilities.
Explanation: When a question asks you to find the "most precise" revision, your job is to match the specific details in the original passage — exact quantities, exact item names, and exact destinations. Vague language, even if technically accurate, fails the precision test. The passage gives you very specific information: two movable platforms went into the scenery bay, and six folding chairs went into the furniture storeroom. Choice B is correct because it preserves every one of these details — the quantities (two, six), the item types (movable platforms, folding chairs), and the distinct destinations (scenery bay, furniture storeroom). Nothing is lost or blurred. Choice A fails because "stage equipment and furniture" strips away the specific quantities and item names, and "appropriate backstage storage areas" collapses two distinct locations into a vague generalization. Choice C introduces the word "props," which never appears in the passage — platforms and folding chairs aren't props — and "storage rooms" again blurs the two separate, named locations. Choice D uses "movable equipment and seating," which is imprecise (platforms aren't just "equipment," and chairs aren't labeled "seating" in the source), and "designated storage facilities" is bureaucratic vagueness that replaces the specific room names. The trap in questions like this is that A and D sound more formal and polished, which can make them feel like improvements. But precision isn't about tone — it's about specificity. Strategy tip: When evaluating revisions for precision, mentally check each one against the original source like a checklist: Do the quantities match? Do the item names match? Do the destinations match? The answer that checks all boxes wins.

Question 6

A software update encrypts passwords saved on a device and automatically signs users out of sessions that have been inactive for thirty minutes. The release announcement concludes, "These things make shared computers safer."

Which revision replaces the vague subject with the most accurate and specific noun phrases?

  1. Password encryption and automatic sign-out after inactivity make shared computers safer. (correct answer)
  2. Saved passwords and inactive sessions make shared computers safer for users.
  3. The software update and its installation process make shared computers safer.
  4. New privacy settings and automatic password deletion make shared computers safer.
Explanation: When a sentence uses a vague pronoun or placeholder like "these things," your job is to replace it with noun phrases that accurately capture what the passage actually describes — no more, no less. The revision must be precise, complete, and faithful to the source material. The passage describes two specific features: (1) encrypting saved passwords and (2) automatically signing users out after thirty minutes of inactivity. Answer A — password encryption and automatic sign-out after inactivity — maps directly onto both of these features. It names the actions the software performs, not vague categories or invented details, making it the most accurate replacement for "these things." Answer B fails because it replaces the actions with the objects acted upon — "saved passwords and inactive sessions" — which are not what make computers safer. The security measures acting on those things are what matter. B also adds "for users," which isn't supported by the original claim. Answer C references "the software update and its installation process," but the passage never mentions an installation process. Introducing unsupported information makes this revision inaccurate, even if it sounds reasonable. Answer D invents "new privacy settings and automatic password deletion" — neither of which appears anywhere in the passage. This is the clearest distractor trap: it sounds tech-related and plausible, but it's fabricated. The key strategy here is to treat the passage as your only source of truth. When replacing vague subjects, ask: Does this noun phrase reflect what the passage explicitly describes? If you're adding, inventing, or shifting focus away from stated actions, the revision is wrong regardless of how natural it sounds.

Question 7

In a greenhouse trial, researchers exposed groups of bean seedlings to increasing salt concentrations. Each week, they measured mean stem height and counted the new leaves produced by each group. A draft report states, "As salinity increased, things about the seedlings declined."

Which revision most precisely expresses the measured result without adding unsupported information?

  1. The overall health of the salt-treated seedlings declined during the trial.
  2. Mean stem height and new-leaf production declined as salinity increased. (correct answer)
  3. The recorded plant measurements declined after the salt treatments began.
  4. Seedling survival and root mass declined as salinity increased.
Explanation: When a question asks you to "precisely express a measured result," your job is to match the language exactly to what the study actually recorded — nothing more, nothing less. Ask yourself: What did the researchers literally measure? The passage tells you directly: mean stem height and new-leaf production. Any answer that goes beyond those two variables is importing unsupported information. B is correct because it names precisely those two variables — mean stem height and new-leaf production — and ties their decline to the independent variable (salinity). Every word is grounded in what the passage describes. A fails because "overall health" is an interpretation, not a measurement. The researchers never assessed health as a category; they tracked specific growth metrics. Choosing A means drawing a conclusion the data doesn't directly support. C is closer but still too vague. "Recorded plant measurements" could refer to anything that was measured — it doesn't specify which measurements declined, so it lacks the precision the question demands. Vagueness is its own kind of inaccuracy in scientific writing. D introduces "seedling survival and root mass," neither of which appears anywhere in the passage. The trial measured stem height and new leaves — not whether seedlings died or how roots changed. D is a classic trap: it sounds scientific and plausible, but it fabricates data points. A useful strategy: when revising scientific claims, mentally check each noun against the passage. If a noun (like "root mass" or "overall health") doesn't appear or logically follow from what was explicitly measured, eliminate that choice. Precision means accounting for what was observed, not what might be true.

Question 8

During an inspection, a custodian found that pine needles and roofing granules had accumulated inside the roof drain. The maintenance report said, "There was something that blocked runoff from the roof."

Which revision most effectively replaces the vague wording with a specific subject and a direct verb?

  1. A clog in the roof drain caused the building's runoff problem.
  2. Loose debris interfered with the building's general drainage system.
  3. Pine needles and roofing granules blocked the roof drain. (correct answer)
  4. Materials from the roof created an obstruction inside the drain.
Explanation: When a question asks you to replace "vague wording" with something "specific" and "direct," you should focus on two things: whether the subject names the exact cause, and whether the verb describes the action without hedging or abstracting it. The original sentence fails on both counts — "something" is a placeholder noun, and "blocked" is buried inside a relative clause. The revision you want should pull the actual nouns from the passage (pine needles and roofing granules) and pair them directly with a strong, active verb. That's exactly what C does: "Pine needles and roofing granules blocked the roof drain." The subject is precise, drawn straight from the inspection findings, and "blocked" is a direct, unambiguous verb in the main clause. Nothing is hidden or softened. A introduces "a clog" as the subject — a vague summary noun that doesn't tell you what caused the clog. It also adds "the building's runoff problem," which drifts away from the specific drain mentioned in the passage. B replaces the actual debris with "loose debris," which is still generic, and "interfered with" is weaker and less direct than "blocked." D uses "materials from the roof" — again, a vague category — and buries the action inside a noun phrase ("created an obstruction") rather than using the precise verb "blocked." Notice that A and D both use nominalization — turning actions or specific things into abstract nouns ("clog," "obstruction," "materials"). This is a common trap. When revising for clarity, concrete nouns and direct verbs almost always beat abstract noun phrases. Train yourself to ask: Can I name the exact thing? Can I say what it did?

Question 9

Before displaying the nineteenth-century letters, the archivist gently flattened their creases and placed each letter in an acid-free sleeve. The exhibit notes initially said that the archivist "did some things to the damaged letters before displaying them."

Which phrase should replace "did some things to the damaged letters" to provide the greatest precision while preserving the passage's meaning?

  1. flattened the creases and placed each letter in an acid-free sleeve (correct answer)
  2. cleaned the stains and repaired each letter with archival adhesive
  3. sorted the letters and entered each document in a digital catalog
  4. restored the handwriting and transcribed each letter for the exhibit
Explanation: When a question asks you to replace vague language with a more precise phrase, your job is to find the option that accurately reflects what the original passage actually describes — not what sounds plausible or impressive. The key word here is precision: the replacement must match the source text exactly, neither adding nor omitting details. The passage tells you specifically what the archivist did: flattened the creases and placed each letter in an acid-free sleeve. Choice A mirrors those two actions word for word, making it the direct, precise replacement for the vague phrase "did some things to the damaged letters." It preserves the passage's meaning without inventing anything new. The distractors are designed to tempt you with actions that sound archivally reasonable but have no basis in the passage. Choice B describes cleaning stains and using archival adhesive — neither action is mentioned anywhere in the text. Choice C introduces sorting and digital cataloging, which the passage never references. Choice D brings up restoring handwriting and transcribing letters — again, completely absent from the source material. All three of these are fabrications: they might describe real archival work, but they contradict the standard of preserving the passage's meaning, which the question explicitly requires. This is a common trap on reading and grammar exams: distractors often include details that feel contextually appropriate, tempting you to choose something that "fits the scene" rather than something that "fits the text." Your strategy is to treat the original passage as your only evidence. Before selecting an answer, ask yourself: Can I find this specific action in the passage? If you can't point to it directly, eliminate it.

Question 10

During a writing workshop, interns practiced outlining claims, integrating quotations into sentences, and editing transitions between paragraphs. An evaluation states, "The instructor went over stuff that would strengthen analytical essays."

Which revision uses precise verbs and nouns while retaining all three workshop topics?

  1. The instructor reviewed writing skills that would improve the interns' analytical essays.
  2. The instructor explained how to outline claims, integrate quotations, and edit transitions. (correct answer)
  3. The instructor reviewed claims, quotations, and transitions in several analytical essays.
  4. The instructor explained how to plan, research, and proofread analytical assignments.
Explanation: When a question asks you to revise vague language using "precise verbs and nouns," your job is twofold: replace weak, general words with specific ones and preserve every detail from the original. The original evaluation mentions three specific workshop activities — outlining claims, integrating quotations, and editing transitions — but buries them under vague language ("went over stuff"). Choice B is the strongest revision because it does both jobs simultaneously. It replaces "went over" with the precise verb explained and "stuff" with the exact three-part content from the passage: outlining claims, integrating quotations, and editing transitions. Nothing is lost, and nothing vague remains. Choice A improves the verb ("reviewed") and adds a clear audience ("interns"), but replaces the three specific topics with the broad phrase "writing skills" — still vague. You lose the concrete content the question requires you to retain. Choice C uses "reviewed" and names all three topics (claims, quotations, transitions), but strips away the action verbs (outlining, integrating, editing). This misrepresents what the instructor actually covered; the workshop was about working with these elements, not just reviewing them as static objects. Choice D introduces four completely different activities — plan, research, and proofread — none of which appear in the original passage. This is a fabrication trap: it sounds polished, but it replaces the actual content rather than refining it. A reliable strategy here: before selecting your answer, make a quick checklist of every specific detail in the original, then verify that your chosen revision accounts for all of them with stronger, more exact language.
