Question 1

Which revision of the second sentence most precisely identifies what surprised the investors?

The six-week construction delay surprised the investors.
The city's review process surprised the investors.
The omission of the drainage study surprised the investors. (correct answer)
The proposed construction schedule surprised the investors.

Explanation: When a question asks you to revise a vague pronoun reference — here, "This surprised the investors" — your job is to trace exactly what the pronoun refers to in context. Don't ask what could have surprised them; ask what the passage tells you surprised them. The third sentence is the key: "they had been assured that every required study was included." This reveals that the investors were caught off guard specifically because a required study was missing — something they believed had been handled. The cause of their surprise was the omission itself, making C, the omission of the drainage study, the most precise and logically supported revision. Choice A is a tempting trap because the six-week delay is dramatic and concrete, but the passage never says the investors were surprised by the delay — it says they were assured the application was complete. Their surprise stems from the cause of the denial, not its downstream consequence. Choice B, the city's review process, is never mentioned as a source of surprise and introduces an idea the passage doesn't support. Choice D, the proposed construction schedule, appears nowhere in the passage at all — it's a fabricated detail that may sound plausible but has zero textual basis. The strategy here is to anchor your revision to textual evidence, not inference. When a passage explains why something happened and how characters reacted, the revision question is testing whether you can match the specific cause to the specific reaction — not whether you can imagine a reasonable explanation. Always look at the sentence following the vague reference for clues about what it actually means.

Question 2

The inspectors met with the contractors after they reviewed the electrical plans. According to the inspection record, the inspectors completed the review before the meeting began.

Which revision most effectively clarifies who reviewed the plans without changing the sequence of events?

After reviewing the plans, the contractors met with the inspectors.
The inspectors met with the contractors after they reviewed the plans.
After the plans were reviewed, the inspectors met with the contractors.
After reviewing the plans, the inspectors met with the contractors. (correct answer)

Explanation: When a sentence contains a pronoun like "they" that could refer to more than one noun, you have an ambiguous pronoun reference — a classic grammar trap. Your job is to find the revision that removes the ambiguity while preserving the original meaning (inspectors reviewed plans, then the meeting happened). The passage tells us the inspectors did the reviewing, so the correct revision must make that crystal clear and keep the same chronological order. Choice D — "After reviewing the plans, the inspectors met with the contractors" — accomplishes both goals perfectly. The participial phrase "after reviewing the plans" is placed directly before "the inspectors," so there's zero ambiguity about who did the reviewing. The sequence is also intact: review first, meeting second. Choice A fails on meaning: it says the contractors reviewed the plans, which contradicts the inspection record. Choice B is essentially the original sentence reworded without fixing anything — "they" still doesn't clearly identify who reviewed the plans, leaving the ambiguity wide open. Choice C uses a passive construction ("the plans were reviewed") that deliberately omits the actor, so while it sidesteps the confusion, it still doesn't tell you who reviewed the plans — which is exactly what the question asks you to clarify. A useful strategy: whenever you see a revision question involving pronouns or participial phrases, immediately ask yourself two questions — Who is doing the action? and Does this match the intended meaning? If either answer is unclear or wrong, eliminate that choice. The best revision names the subject explicitly and positions modifying phrases right next to the noun they describe.

Question 3

The technician disconnected the server from the backup drive after it overheated. Temperature records show that the drive reached 82 degrees, while the server remained within its normal operating range.

Which revision most clearly identifies the overheated component while preserving the original chronology?

After the server overheated, the technician disconnected it from the backup drive.
The technician disconnected both devices after the server and drive had overheated.
After the backup drive overheated, the technician disconnected it from the server. (correct answer)
The technician disconnected the server after its operating range had overheated.

Explanation: When a sentence contains a pronoun like "it" or "they" that could refer to more than one noun, you're dealing with ambiguous pronoun reference — a core syntax concept tested frequently on grammar exams. Your job here is to find the revision that both clarifies which device overheated and keeps the original sequence of events (overheating first, then disconnection). The passage's second sentence tells you directly: the drive reached 82 degrees while the server stayed within its normal range. That means the backup drive overheated — not the server. Choice C captures this precisely: "After the backup drive overheated, the technician disconnected it from the server." Now "it" unambiguously refers to the backup drive, the pronoun is clarified, and the chronology (overheating → disconnection) is preserved. Choice A is the most tempting distractor because it fixes the ambiguity and keeps the chronology — but it incorrectly names the server as the overheated component, which contradicts the temperature data in the passage. Choice B introduces a new factual error by claiming both devices overheated, which the evidence doesn't support. Choice D is grammatically awkward and logically incoherent — an "operating range" cannot overheat; the phrase describes a measurement boundary, not a physical component. A useful strategy: whenever a revision question involves pronouns, trace each pronoun back to its intended antecedent and cross-check that antecedent against any factual details in the passage. Grammar accuracy and factual accuracy must both hold — a revision that's grammatically clean but contradicts the text is still wrong.

Question 4

The policy requires supervisors to document complaints before discussing them with employees. A later provision explains that employees may respond to the documented complaints during those discussions.

Which revision most clearly identifies what supervisors must discuss with employees?

The policy requires supervisors to document employees before discussing complaints with them.
The policy requires employees to document complaints before discussing them with supervisors.
The policy requires supervisors to document complaints before discussing those complaints with employees. (correct answer)
The policy requires supervisors to document complaints before employees discuss the supervisors involved.

Explanation: When a sentence contains a pronoun like "them" or "those," you should always ask: what does this pronoun refer to? If the answer is ambiguous — meaning the pronoun could logically point to more than one noun — the sentence has a pronoun reference error. That's exactly what this question is testing. In the original passage, "discussing them with employees" uses "them," which could refer to either the complaints or the employees mentioned earlier. That ambiguity is the core problem. Option C fixes this by replacing the vague pronoun with the explicit noun phrase: "discussing those complaints with employees." Now there's no guesswork — supervisors must discuss the documented complaints with employees, which also aligns logically with the later provision about employees responding to documented complaints. Option A introduces a new error by repositioning "employees" as the object of "document," implying supervisors must document employees themselves rather than the complaints — a significant meaning distortion. Option B flips the roles entirely, making employees responsible for documenting complaints and bringing them to supervisors, which contradicts the passage's clear assignment of responsibilities. Option D creates a completely different and unsupported meaning: that employees are discussing the supervisors involved, which has no basis in the original passage and changes the subject of the discussion altogether. The key strategy here: whenever you spot a pronoun in an underlined or questioned portion, trace it back to its antecedent. If two or more nouns could claim that pronoun, the sentence needs revision. Replacing the pronoun with the specific noun it intends to reference is almost always the clearest fix.

Question 5

Maya asked Tessa to place the samples in her cabinet. Laboratory policy required the samples to remain in the cabinet assigned to Maya, who was responsible for calibrating them.

Which revision of the first sentence uses direct quotation to eliminate the ambiguity and preserve the intended location?

Maya said to Tessa, "Please place the samples in your cabinet."
Maya said to Tessa, "Please place the samples in my cabinet." (correct answer)
Maya said to Tessa, "Please place the samples in her cabinet."
Maya said to Tessa, "Please place the samples in our cabinet."

Explanation: When a sentence contains a pronoun that could refer to more than one person, it creates ambiguous reference — the reader can't tell whose noun the pronoun replaces. The original sentence ("place the samples in her cabinet") is unclear because "her" could mean either Maya's cabinet or Tessa's cabinet. Converting indirect speech to direct quotation fixes this because the speaker's perspective becomes the anchor — pronouns shift relative to who is talking. Since Maya is the one speaking, her own cabinet becomes "my cabinet" in her mouth. The second sentence of the passage confirms the intended meaning: the samples must stay in Maya's cabinet, the one assigned to her for calibration. That makes choice B — "Please place the samples in my cabinet" — the correct revision. It eliminates ambiguity by having Maya refer to her own cabinet with the first-person possessive "my." Choice A uses "your cabinet," which would direct Tessa to place the samples in Tessa's cabinet — the opposite of what lab policy requires. Choice C keeps the original pronoun "her" inside the quotation marks, which is actually ungrammatical in direct speech (a speaker wouldn't refer to herself as "her") and preserves the ambiguity rather than resolving it. Choice D uses "our cabinet," implying shared ownership, which is unsupported by the passage and still doesn't clarify whose assigned cabinet holds the samples. A useful rule of thumb: when revising for pronoun clarity using direct quotation, always ask who is speaking and what relationship does that speaker have to the noun? That relationship determines which pronoun belongs in the quote.

Question 6

The committee postponed the vote after counsel questioned the revised clause, which angered the sponsor. The sponsor supported the legal review but objected to missing the scheduled vote.

Which revision most clearly conveys the source of the sponsor's anger?

Counsel's questions about the revised clause angered the sponsor.
The committee's postponement of the vote angered the sponsor. (correct answer)
The wording of the revised clause angered the sponsor.
Counsel's participation in the scheduled vote angered the sponsor.

Explanation: When a passage contains a misplaced or ambiguous modifier, your job is to trace what actually caused a specific reaction — not just what happened nearby. Here, the passage tells you the sponsor supported the legal review (counsel's questions) but objected to missing the scheduled vote. That objection is your key: the sponsor was fine with the questioning itself but upset that the committee postponed the vote as a result. B captures this precisely. The committee's postponement — not the questioning — is what denied the sponsor the scheduled vote. This aligns directly with the passage's clarification that the sponsor supported the legal review. A is tempting because counsel's questions appear right before "which angered the sponsor," making it easy to misread the modifier as pointing there. But the passage explicitly states the sponsor supported the legal review, so counsel's questions cannot be the source of the anger. C invents a grievance not supported by the passage. The sponsor's frustration concerns the procedural outcome (the missed vote), not any dissatisfaction with the clause's wording itself. D distorts the facts entirely. Counsel participated in a legal review, not the scheduled vote. This choice confuses two separate events and misrepresents counsel's role. A useful strategy: when a passage both describes an event and clarifies a character's position on it, let that clarification override surface-level proximity. The modifier "which angered the sponsor" is ambiguous, so you must use the sponsor's stated attitude — support for the review, objection to missing the vote — to pin down the correct referent. That context resolves the ambiguity and points clearly to B.

Question 7

Elena submitted the quarterly budget to Priya for an independent audit. She later corrected the freight estimate. The revision log identifies Priya as the person who made the correction.

Which revision of the second sentence most clearly eliminates the ambiguous pronoun while preserving the meaning established by the passage?

Priya later corrected the freight estimate. (correct answer)
Elena later corrected the freight estimate.
She herself later corrected the freight estimate.
The two colleagues later corrected the freight estimate.

Explanation: When a pronoun like "she" could refer to more than one noun previously mentioned, you have an ambiguous pronoun. The fix requires replacing that pronoun with a specific noun — but you must also verify which meaning the surrounding context actually establishes. Here, the revision log explicitly identifies Priya as the one who made the correction, so the replacement must name Priya, not Elena. Choice A does exactly this. Replacing "She" with "Priya" removes the ambiguity entirely and aligns perfectly with the contextual evidence provided by the third sentence. The meaning is preserved and the sentence is clear — making A the correct answer. Choice B introduces a different problem: it names Elena as the one who corrected the estimate, which directly contradicts the revision log mentioned in the passage. Clarity achieved through inaccuracy is not a valid revision. Choice C keeps the original ambiguity alive. Adding "herself" for emphasis still leaves "She" as the subject — and since both Elena and Priya are candidates for that pronoun, the sentence remains just as unclear as before. Emphasis is not the same as specificity. Choice D changes the meaning entirely by suggesting both colleagues made the correction together, which the passage never supports. Introducing new information that wasn't implied is a distortion, not a clarification. Your strategy here: whenever you're asked to fix an ambiguous pronoun, do two things — (1) identify which specific person or thing the pronoun should logically refer to based on context clues in the passage, and (2) confirm that the replacement doesn't alter or invent meaning. Both clarity and accuracy must be satisfied simultaneously.

Question 8

I interviewed the assistant of the director who had approved the grant. The approval memorandum was signed solely by the assistant, who held independent authority to approve grants of this type.

Which revision most clearly identifies the person who approved the grant?

I interviewed the assistant after the director, who had approved the grant.
I interviewed the assistant whom the director had approved for the grant.
I interviewed the assistant of the grant-approving director.
I interviewed the director's assistant, who had approved the grant. (correct answer)

Explanation: When a sentence contains a relative clause like "who had approved the grant," you must ask: what noun does that clause actually modify? Relative clauses attach to the nearest preceding noun they logically describe — and when that attachment is ambiguous, the meaning breaks down. That's exactly what's being tested here. The original sentence fails because "who had approved the grant" could modify either "the assistant" or "the director." The passage clarifies it was the assistant who approved, so the revision must make that unambiguous. Choice D — "I interviewed the director's assistant, who had approved the grant" — achieves this cleanly. By restructuring "the assistant of the director" into the possessive "the director's assistant," the single noun phrase "the director's assistant" becomes the only antecedent for the relative clause. There's no dangling ambiguity. Choice A introduces new confusion by implying the director approved the grant ("the director, who had approved the grant"), directly contradicting the passage. Choice B changes the meaning entirely — "the assistant whom the director had approved for the grant" suggests the director approved the assistant as a person, not that the assistant approved the grant. Choice C ("the grant-approving director") incorrectly attributes the approval to the director, which again contradicts the passage's clarification. A useful strategy: when revising sentences with relative clauses, mentally draw an arrow from the clause back to the noun it's supposed to describe. If that arrow could point to more than one noun, the sentence is ambiguous and needs restructuring — usually through possessives or reordering — to force a single, clear target.

Question 9

The board notified the faculty senate that they would release the findings on Friday. The meeting minutes assign responsibility for the release to the board chair.

Which revision most effectively eliminates the ambiguity without assigning the action to the wrong organization?

The board notified the faculty senate that the board would release the findings on Friday. (correct answer)
The board notified the faculty senate that the senate would release the findings on Friday.
The board notified the faculty senate, and they would release the findings on Friday.
After the board notified the faculty senate, it would release the findings on Friday.

Explanation: When a pronoun like they or it could refer to more than one noun, you have a pronoun ambiguity problem. Here, "they would release the findings" is unclear because they could logically refer to either the board or the faculty senate. The second sentence is your critical clue: the meeting minutes confirm the board chair — and by extension, the board — is responsible for the release. Any revision must both eliminate the ambiguity and preserve that meaning. Choice A replaces they with the board, directly naming the correct antecedent. The sentence is now unambiguous, and responsibility stays exactly where the minutes place it — with the board. This is your correct answer. Choice B is a trap worth examining carefully. It does eliminate the pronoun ambiguity, but it reassigns the action to the faculty senate — directly contradicting what the meeting minutes establish. Eliminating ambiguity the wrong way is still wrong. Choice C keeps the ambiguous they and simply restructures the sentence around it. Splitting the clauses with a comma and conjunction doesn't clarify which organization they refers to; the pronoun problem is completely unresolved. Choice D swaps they for it, which is equally ambiguous — it could still refer to either the board or the faculty senate. Changing the pronoun's form doesn't fix the underlying reference problem. Strategy tip: On pronoun ambiguity questions, always identify two things — which pronoun is unclear, and which antecedent is correct based on context. The right revision must do both jobs: clarify and preserve the intended meaning.

Question 10

The archive contains letters written by Ada Chen and biographies of Chen written by Luis Ortega. These were digitized last spring. The scanning log shows that only the correspondence collection was completed at that time.

Which revision of the second sentence best eliminates the ambiguous demonstrative pronoun?

Ortega's biographies of Chen were digitized last spring.
Chen's letters were digitized last spring. (correct answer)
The archive's materials were digitized last spring.
They were the items digitized last spring.

Explanation: When a sentence contains a demonstrative pronoun like "these," "those," or "they," you need to ask: what exactly does this pronoun refer to? If the answer isn't crystal clear, the pronoun is ambiguous. Here, "These were digitized last spring" is problematic because "these" could point to either the letters written by Chen or the biographies written by Ortega — the passage introduces both in the previous sentence. The fix requires replacing the vague pronoun with a specific noun phrase. The third sentence then narrows things down, telling us only the correspondence collection (the letters) was completed. This context confirms that the digitized items were Chen's letters, making B — "Chen's letters were digitized last spring" — the correct revision. It eliminates the ambiguity by naming exactly which materials were digitized, and it aligns logically with what the scanning log reveals. Choice A replaces the pronoun with "Ortega's biographies of Chen," which is actually the wrong collection according to the scanning log — only the correspondence was completed. Choice C says "the archive's materials," which is even vaguer than the original pronoun; it doesn't distinguish between letters and biographies at all. Choice D simply swaps one pronoun ("these") for another ("they"), doing nothing to resolve the ambiguity — "they" still has two possible antecedents. A useful rule of thumb: whenever you revise to fix a pronoun reference, ask whether a reader encountering the sentence in isolation could identify the referent without rereading the passage. If not, only a specific noun phrase — not another pronoun — will truly solve the problem.
