Question 1

When a reviewer challenges an editor, they should document the objection in the project file.

The writer intends to assign responsibility for documenting the objection only to the editor. Which revision most clearly conveys that requirement?

  1. When a reviewer challenges an editor, the editor should document the objection in the project file. (correct answer)
  2. When a reviewer challenges an editor, the reviewer should document the objection in the project file.
  3. When a reviewer challenges an editor, they should then document the objection in the project file.
  4. When a reviewer challenges an editor, both should document the objection in the project file.
Explanation: When a sentence uses a pronoun like "they" to refer back to multiple nouns, you face a classic pronoun ambiguity problem. The reader can't tell which noun the pronoun replaces. Questions like this test whether you can identify that ambiguity and choose a revision that eliminates it by replacing the vague pronoun with a specific noun. In the original sentence, "they" could logically refer to either the reviewer or the editor — both are singular antecedents that "they" might stand in for. Since the writer wants only the editor to bear responsibility for documenting the objection, the fix is straightforward: replace the ambiguous "they" with the noun "the editor." That's exactly what A does. By substituting "the editor should document," it removes all doubt about who is responsible. B makes the opposite assignment — it names "the reviewer" as the one who must document, which contradicts the writer's stated intention of assigning that duty to the editor. C keeps the ambiguous "they" and only adds the word "then," which changes the timing slightly but does nothing to clarify who is responsible — the core problem remains unsolved. D assigns responsibility to both parties equally with "both should document," which again contradicts the requirement to assign responsibility to the editor alone. A useful strategy: whenever you see "they," "them," or "their" in a sentence with two or more possible antecedents, ask "Who exactly does this refer to?" If the answer isn't immediate and certain, the pronoun needs to be replaced with a specific noun.

Question 2

Jordan placed the laptop beside the projector before connecting it to the wireless network.

The writer intends to say that Jordan connected the projector to the wireless network. Which revision is clearest and most faithful to that meaning?

  1. Jordan placed the laptop beside the projector before connecting the laptop to the wireless network.
  2. Before connecting it to the wireless network, Jordan placed the laptop beside the projector.
  3. Jordan placed the laptop beside the projector before connecting the projector to the wireless network. (correct answer)
  4. Jordan placed both devices together before connecting them to the wireless network.
Explanation: When a sentence contains a pronoun like it, they, or them, that pronoun must clearly and unambiguously refer to one specific noun — this is called pronoun reference. Questions like this test whether you can identify pronoun ambiguity and choose a revision that eliminates it while preserving the writer's intended meaning. In the original sentence, "connecting it to the wireless network" is ambiguous because it could refer to either the laptop or the projector — both are singular nouns mentioned earlier. The writer's intent, however, is specifically that Jordan connected the projector, so the revision must make that crystal clear. Choice C does exactly this by replacing it with the projector: "Jordan placed the laptop beside the projector before connecting the projector to the wireless network." The structure stays intact, the meaning is precise, and no information is distorted. C is your answer. Choice A also eliminates the ambiguity, but it replaces it with the laptop — the opposite of what the writer intends. That makes it faithful to clarity but unfaithful to meaning. Choice B rearranges the clause order but keeps it, so the pronoun ambiguity remains completely unresolved — a cosmetic fix that solves nothing. Choice D introduces both devices and them, which changes the meaning entirely: now both the laptop and projector are being connected to the network, which contradicts the writer's stated intent. Strategy tip: When you see a revision question involving pronouns, always anchor your choice to two criteria simultaneously — clarity and the writer's intended meaning. Satisfying only one of the two is a trap the wrong answers are designed to set.

Question 3

The contractor revised the cost estimates, and the architect discovered a scheduling conflict. This caused the board to postpone the vote.

The writer intends to identify the scheduling conflict—not the revised estimates or the discovery itself—as the reason for the postponement. Which revision of the second sentence is clearest?

  1. This unexpected development caused the board to postpone the vote.
  2. The scheduling conflict caused the board to postpone the vote. (correct answer)
  3. The revised cost estimates caused the board to postpone the vote.
  4. The architect's discovery caused the board to cancel the scheduled vote.
Explanation: When a question asks you to identify which revision best captures a specific cause for an outcome, you're being tested on pronoun/antecedent clarity and precise reference. The key question to ask yourself is: does this sentence point to exactly the right thing, with no ambiguity? The passage ends with "This caused the board to postpone the vote," where "This" is vague — it could refer to the revised estimates, the scheduling conflict, or the discovery itself. Since the writer's intent is specifically to blame the scheduling conflict, the revision must name that conflict directly and unambiguously. Choice B does exactly that: "The scheduling conflict caused the board to postpone the vote." It replaces the vague "This" with the precise noun phrase, eliminating any confusion about what triggered the postponement. This is your correct answer. Choice A swaps "This" for "This unexpected development," which is still vague — it doesn't tell you which development caused the delay, so it fails the clarity test despite sounding polished. Choice C actively contradicts the writer's intent by naming the revised cost estimates as the cause, which is precisely what the question says the writer does not want to emphasize. Choice D changes both the subject (crediting the architect's discovery, not the conflict itself) and the outcome (switching "postpone" to "cancel"), introducing two new distortions that misrepresent the passage's meaning. A useful rule of thumb: whenever a sentence begins with a vague pronoun like this, it, or that, ask yourself what noun it could reasonably point to — if there's more than one candidate, clarity demands you replace it with the specific term.

Question 4

The inspectors met with the warehouse managers on Friday. On Monday, they submitted revised inventory counts to the agency.

The revised counts were submitted by the warehouse managers. Which revision of the second sentence makes that fact unambiguous without suggesting joint action?

  1. On Monday, the inspectors submitted revised inventory counts to the agency.
  2. On Monday, the warehouse managers submitted revised inventory counts to the agency. (correct answer)
  3. On Monday, both groups submitted revised inventory counts to the agency.
  4. On Monday, revised inventory counts were submitted to the agency by the participants.
Explanation: Pronoun ambiguity is one of the most commonly tested concepts in grammar and syntax questions. When a pronoun like "they" appears after two possible antecedents — here, "inspectors" and "warehouse managers" — the reader cannot determine who is actually being referenced. Your job is to choose the revision that resolves this ambiguity precisely, according to the stated condition: the warehouse managers submitted the counts, and no joint action is implied. Option B does exactly this. Replacing "they" with "the warehouse managers" names the correct subject directly, eliminates any guesswork, and attributes the action to one group alone. It satisfies both requirements of the question simultaneously. Now consider why the other options fall short. Option A replaces "they" with "the inspectors," which resolves the ambiguity but attributes the action to the wrong group — directly contradicting the premise that the warehouse managers submitted the counts. Option C introduces "both groups," which implies joint action, a condition the question explicitly forbids. Option D uses a vague phrase, "the participants," which is arguably more ambiguous than the original — it doesn't clarify which participants submitted the counts, and it still fails to name the warehouse managers. The strategy here is to treat pronoun ambiguity questions as having two filters: first, does the revision clarify who performed the action? Second, does it do so accurately according to the given context? Wrong answers often resolve the ambiguity but introduce a new error — misattributing the action or implying unintended meaning. Always check your revision against both filters before choosing.

Question 5

Maya told Elena that her analysis omitted several years of data.

The writer intends to say that the analysis belongs to Maya. Which revision most clearly expresses that meaning without introducing a new relationship between the ideas?

  1. Noticing omitted data in Elena's analysis, Maya spoke to her about the problem.
  2. Maya told Elena that Maya's analysis omitted several years of data. (correct answer)
  3. Maya told Elena that her own analysis omitted several years of data.
  4. Because Elena had omitted data from the analysis, Maya informed her of the problem.
Explanation: When a sentence contains a pronoun like her or his that could refer to more than one person, you have a pronoun ambiguity problem. The original sentence — "Maya told Elena that her analysis omitted several years of data" — uses her, which could belong to either Maya or Elena. The question asks you to fix this so the analysis clearly belongs to Maya, without changing the core relationship between the ideas (Maya telling Elena something). The cleanest fix is to replace the ambiguous pronoun with the specific noun it's meant to represent. Answer B does exactly this: "Maya told Elena that Maya's analysis omitted several years of data." Substituting the proper noun Maya's for her eliminates any confusion while preserving the original sentence structure perfectly. Answer C is the most tempting distractor. The phrase her own feels emphatic, but it doesn't actually resolve the ambiguity — her own still refers to whoever her refers to, which remains unclear when two women are mentioned. It sounds like a fix without functioning as one. Answer A changes the sentence structure entirely by making Maya the one who noticed the omission, which introduces a new implication about who discovered the problem — that's a new relationship between ideas, which the question explicitly forbids. Answer D similarly rewrites the sentence to focus on Elena omitting data, shifting emphasis and implying Elena's fault rather than simply attributing ownership of the analysis to Maya. Your strategy: whenever you see pronoun ambiguity, ask yourself "can I replace this pronoun with a specific name?" If yes, that replacement is almost always the safest, clearest revision.

Question 6

The council rejected the developer's proposal for a waterfront tower, which alarmed nearby residents.

The writer intends to say that the council's rejection—not the proposal, the tower, or the developer—alarmed the residents. Which revision most clearly conveys that meaning?

  1. Nearby residents were alarmed by the council's rejection of the waterfront-tower proposal. (correct answer)
  2. The proposed waterfront tower alarmed nearby residents after the council rejected it.
  3. The developer's proposal alarmed nearby residents when the council rejected the plan.
  4. The council rejected the developer because the waterfront proposal alarmed nearby residents.
Explanation: When a sentence contains a relative clause beginning with "which," pay close attention to what noun that clause modifies — it will be whatever noun sits closest to it. This is the concept of ambiguous pronoun/clause reference, and it's a classic trap on grammar and syntax exams. In the original sentence, "which alarmed nearby residents" could logically refer to the proposal, the tower, or the rejection — all three nouns appear nearby. The writer's intended meaning (the rejection alarmed residents) gets buried in that ambiguity. The fix is to restructure the sentence so the intended subject is unmistakable. Choice A solves the problem cleanly by making "the council's rejection" the explicit subject of the alarming action: residents were alarmed by the council's rejection. There's no ambiguity — the rejection is front and center as the cause. Choice B makes the tower the subject of the alarming, contradicting the writer's intent entirely. The tower alarms residents, not the rejection. Choice C introduces a similar mismatch — it implies the proposal alarmed residents, which again isn't what the writer intended. The council's rejection disappears as the cause. Choice D reverses the cause-and-effect relationship altogether, suggesting the council rejected the developer because residents were alarmed. That's a completely different meaning from the original. A useful strategy: when a question asks you to clarify what caused something, look for the answer choice that places the intended cause directly in the subject or agent position of the sentence. Burying the cause in a modifier or clause almost always creates confusion.

Question 7

The biography of Ada Lovelace was displayed beside the portrait of Marie Curie until it was moved into a secure case.

The writer intends to say that the biography was moved into the secure case. Which revision best avoids the unclear reference?

  1. The biography of Ada Lovelace was displayed beside the portrait of Marie Curie until the biography was moved into a secure case. (correct answer)
  2. The biography of Ada Lovelace was displayed beside the portrait of Marie Curie until the portrait was moved into a secure case.
  3. The biography of Ada Lovelace remained beside Marie Curie's portrait until the work was moved into a secure case.
  4. The biography and the portrait were displayed together until they were moved into a secure case.
Explanation: When a pronoun like "it" appears in a sentence with two or more possible antecedents, readers can't be sure which noun it refers to — this is called an ambiguous pronoun reference. The original sentence contains both "biography" and "portrait," so "it was moved" leaves the reader guessing which item ended up in the secure case. The fix is straightforward: replace the ambiguous pronoun with the specific noun the writer intends. Choice A does exactly this — substituting "the biography" for "it" — so the sentence clearly communicates that the biography, not the portrait, was moved. The meaning is unambiguous and the writer's intention is fully preserved. Choice B introduces a different problem: it replaces "it" with "the portrait," which directly contradicts the writer's stated intention that the biography was moved. Choosing B would change the meaning of the sentence entirely. Choice C swaps in the word "the work," which is vague — a reader unfamiliar with the context still can't determine whether "the work" refers to the biography or the portrait. It trades one ambiguous reference for another. Choice D shifts the subject entirely by combining both objects into "the biography and the portrait" and using "they," which implies both were moved — again contradicting the writer's intention to describe only the biography being relocated. A useful habit: whenever you spot "it," "they," "this," or "that" near multiple nouns, ask yourself "Could this pronoun point to more than one thing?" If yes, the safest revision replaces the pronoun with the precise noun the writer means.

Question 8

The foundation notified the university that its grant rules had changed.

The writer intends to say that the foundation had changed the rules governing its grants. Which revision makes ownership of the rules clearest?

  1. The foundation notified the university that the university's grant rules had changed.
  2. The foundation and the university announced that their grant rules had changed.
  3. The foundation notified the university that the institution's grant rules had changed.
  4. The foundation notified the university that the foundation's grant rules had changed. (correct answer)
Explanation: Whenever a sentence contains the word "its" or other pronouns that could refer to more than one noun, you're being tested on pronoun ambiguity — a core grammar concept. The fix is always to replace the vague pronoun with the specific noun it's meant to represent. In the original sentence, "its grant rules" is ambiguous because "its" could logically refer to either the foundation or the university — both are mentioned. The writer's intent is specifically that the foundation's own grant rules had changed, so the revision must make that ownership unmistakable. Choice D does exactly this: "the foundation notified the university that the foundation's grant rules had changed." By replacing "its" with "the foundation's," there is zero ambiguity about who owns the rules. Choice A substitutes "the university's grant rules," which actually reverses the intended meaning — it implies the university's rules changed, not the foundation's. Choice B introduces a plural subject ("the foundation and the university") and the word "their," which creates new ambiguity about whose rules are meant, while also changing the meaning of the sentence from a notification to a joint announcement. Choice C uses "the institution's," which is vague in a different way — "institution" could refer to either the foundation or the university, so the ambiguity is simply swapped for a different kind of vagueness. When you spot a pronoun like its, their, or they in a revision question, immediately ask: could this pronoun point to more than one noun? If yes, the fix is to replace the pronoun with the explicit noun the writer intends.

Question 9

The policy prohibits employees from discussing client records with supervisors unless they have written permission.

The policy writers mean that employees must obtain written permission before discussing the records. Which revision most clearly states that condition?

  1. The policy prohibits employees from discussing client records with supervisors unless they first obtain written permission.
  2. The policy prohibits employees from discussing client records with supervisors unless the supervisors have obtained written permission.
  3. The policy prohibits employees from discussing client records with supervisors unless the employees have obtained written permission. (correct answer)
  4. The policy prohibits employees from discussing client records unless written permission from supervisors is available.
Explanation: When a sentence contains a pronoun like "they," your first job is to ask: who does this pronoun actually refer to? In the original sentence, "unless they have written permission" is ambiguous — "they" could logically refer to either the employees or the supervisors, both of which are mentioned earlier. This type of error is called ambiguous pronoun reference, and fixing it requires replacing the vague pronoun with a specific noun phrase. The intended meaning, as the question tells you, is that employees must obtain written permission. Choice C states this explicitly: "unless the employees have obtained written permission." By naming employees directly, it eliminates any confusion about who needs the permission and adds "have obtained," which clarifies that permission must be secured beforehand. Choice A keeps the pronoun "they," which still leaves the ambiguity completely unresolved — you still can't tell whether "they" means employees or supervisors. Choice B goes in the opposite direction from the intended meaning, specifying that supervisors must obtain permission, which contradicts what the policy writers meant. Choice D restructures the sentence in a way that removes supervisors from the permission clause entirely, implying that some unnamed written permission just needs to "be available" — this muddles the relationship between who grants and who obtains the permission. The study tip here is to treat every pronoun as a potential trap on grammar revision questions. Ask yourself: if you removed the rest of the sentence, could the pronoun still refer to more than one noun? If so, the sentence needs revision — and the fix is almost always to replace the pronoun with the precise noun.

Question 10

The archive lent the museum the portrait after it completed a major renovation.

The renovation was completed by the museum. Which revision most effectively eliminates the unclear pronoun reference while preserving the sequence of events?

  1. After the archive completed a major renovation, it lent the portrait to the museum.
  2. The archive, after completing a major renovation, lent the museum the portrait.
  3. Once the major renovation was complete, it lent the museum the portrait.
  4. After the museum completed a major renovation, the archive lent the portrait to the museum. (correct answer)
Explanation: When a pronoun like "it" or "they" could logically refer to more than one noun in a sentence, you have an unclear pronoun reference — a classic grammar error that tests your ability to match pronouns unambiguously to their antecedents. The question also adds a layer: you must preserve a specific sequence of events (the museum renovated first, then the archive lent the portrait). Answer D does both jobs cleanly. By naming "the museum" explicitly as the subject of the renovation clause and "the archive" as the subject of the main clause, it eliminates any ambiguity about who did what — and the subordinate clause "After the museum completed a major renovation" clearly establishes that the renovation came first. Here's why the other options fall short. A replaces the ambiguous "it" with "the archive," but this contradicts the premise — the question tells you the museum completed the renovation, not the archive. B uses the participial phrase "after completing a major renovation," which grammatically attributes the renovation to the archive (the subject of the main clause) — again, the wrong actor. C attempts a passive construction to sidestep the pronoun problem but then immediately reintroduces "it" with no clear antecedent, leaving the original ambiguity completely intact. A useful strategy: whenever you spot a pronoun like "it" near two possible antecedents, ask yourself "who actually did this action?" then check whether each answer choice names that actor explicitly and correctly. If a choice swaps in a pronoun or misattributes the action, eliminate it immediately.
