Question 1
The teacher told the student that she needed to study more.
In this sentence, 'she' is unclear. Which sentence BEST fixes the unclear reference?
- The teacher told the student that the student needed to study more. (correct answer)
- The teacher told her that she needed to study more.
- She told the student that she needed to study more often.
- The teacher and the student both agreed that she should study.
Explanation: When a pronoun like "she" or "her" could refer to more than one person in a sentence, it creates what's called an unclear pronoun reference. Your job is to find the revision that removes all confusion about who "she" means.
In the original sentence, "she" could refer to either the teacher or the student — the reader has no way to know. The best fix replaces the unclear pronoun with a specific noun so there's zero doubt. Choice A does exactly this: "The teacher told the student that the student needed to study more." By replacing "she" with "the student," the sentence becomes perfectly clear. Yes, repeating "the student" might feel a little repetitive, but clarity is more important than avoiding repetition here.
Choice B ("The teacher told her that she needed to study more") actually makes things worse — now both "her" and "she" are unclear pronouns, and you still don't know who is who. Choice C ("She told the student that she needed to study more often") introduces a new problem: now "she" appears twice at the start and middle, and neither one is identified — the teacher has disappeared from the sentence entirely. Choice D ("The teacher and the student both agreed that she should study") changes the meaning of the sentence completely; the original says the teacher told the student, not that they agreed — and "she" is still unclear.
A good strategy: whenever you see a pronoun in a sentence with two people of the same gender, ask yourself, "Could this pronoun point to either person?" If yes, replace it with a specific name or noun.
Question 2
Sara gave her report to the supervisor. Afterward, she left the office.
A student says the second sentence is unclear. Another student says it is perfectly clear. Who is RIGHT, and why?
- The first student is right because 'she' could refer to Sara or the supervisor, so a noun must replace 'she' to remove all possible doubt.
- The second student is right because 'she' always refers to the most recently mentioned noun, so the grammar rule makes the sentence clear.
- The first student is right because 'afterward' is a confusing transition word that makes the whole second sentence difficult to follow.
- The second student is right because 'she' clearly refers to Sara, who is the main subject of both sentences, and no real confusion exists. (correct answer)
Explanation: When you see a question about pronoun clarity, ask yourself: Could a real reader genuinely be confused about who the pronoun refers to? Not every "could" creates real confusion — context matters enormously.
In this passage, Sara is the clear main subject of both sentences. She is the one who "gave her report," and she is the one the story follows. When the second sentence says "she left the office," any reasonable reader immediately understands that Sara left. There is no competing female character who could logically be the one leaving — the supervisor received the report and would have no obvious reason to leave her own office. D is correct because "she" refers naturally and unmistakably to Sara, and no genuine confusion exists.
A is wrong because it overstates the problem. Yes, both Sara and the supervisor are female, so technically "she" could point to either — but grammar isn't just about technical possibility. It's about whether a real reader would actually be confused. Here, they wouldn't be. A sets up an unrealistic standard that would require replacing pronouns in nearly every sentence. B is wrong because there is no grammar rule stating that "she" always refers to the most recently mentioned noun — that's a made-up rule. Pronoun reference depends on context and logic, not mechanical recency. C is wrong because "afterward" is a perfectly common, beginner-friendly transition word meaning "after that." It adds clarity, not confusion.
Your study tip: On pronoun clarity questions, don't ask "could this theoretically be confusing?" Ask "would a normal reader actually be confused?" That's the real standard.
Question 3
Ana visited her grandmother before she left for the airport.
Which sentence BEST revises the passage to make the pronoun reference clear?
- Ana visited her grandmother, and then she left for the airport.
- Before the grandmother left for the airport, Ana visited her there.
- Ana visited her grandmother before Ana left for the airport. (correct answer)
- She visited her grandmother before she left for the airport quickly.
Explanation: When a sentence contains a pronoun like "she" or "her," you need to make sure the reader can clearly tell who that pronoun refers to. This is called clear pronoun reference. If two people are mentioned and a pronoun could point to either one, the sentence becomes confusing.
In the original sentence — "Ana visited her grandmother before she left for the airport" — the word "she" is the problem. Does "she" mean Ana, or the grandmother? The reader cannot be sure. The best fix is to replace the unclear pronoun with the specific name it refers to.
Choice C does exactly that: "Ana visited her grandmother before Ana left for the airport." By replacing "she" with "Ana," there is no confusion about who is leaving for the airport. This is the correct answer.
Choice A splits the sentence with "and then," but "she" still appears without a clear reference — both Ana and the grandmother are still possible antecedents, so the confusion remains.
Choice B restructures the sentence awkwardly. Saying "Ana visited her there" introduces a new unclear pronoun ("her") and the phrase "there" adds unnecessary confusion without solving the original problem.
Choice D keeps the original "she" problem completely intact and only adds the word "quickly" at the end, which does nothing to clarify who left for the airport.
A useful tip: whenever you spot a pronoun in a sentence with two people of the same gender, ask yourself, "Could this pronoun refer to either person?" If yes, replacing the pronoun with the correct name is almost always the best fix.
Question 4
My aunt and my mother both love cooking. She makes soup every Sunday.
Which revision of the second sentence BEST maintains clear reference?
- She and my mother make soup every single Sunday together at home.
- My aunt makes soup every Sunday, and so does she on weekends.
- My aunt makes soup every Sunday for the family. (correct answer)
- Every Sunday, she cooks soup for the whole family at home.
Explanation: When a sentence uses a pronoun like "she" or "her," readers need to know exactly who it refers to. This is called pronoun reference, and it becomes a problem when two or more people could match that pronoun. In the passage, "my aunt" and "my mother" are both mentioned — so when the next sentence says "She makes soup every Sunday," a reader cannot tell which woman is meant. Your job is to find the revision that removes this confusion.
Choice C fixes the problem cleanly: "My aunt makes soup every Sunday for the family." It replaces the unclear "she" with the specific name "my aunt," so there is zero confusion about who is cooking. This is the best revision.
Choice A tries to fix the sentence but actually creates a new problem — it says "she and my mother," which still uses the vague "she" without identifying who she is. The extra detail ("every single Sunday together at home") does not solve the pronoun issue.
Choice B is even more confusing. It names "my aunt" in the first part but then says "so does she on weekends" — now "she" could mean the mother or some other person, making the reference murkier than before.
Choice D keeps the original problem entirely. "She cooks soup" still does not tell the reader whether "she" is the aunt or the mother.
A helpful tip: whenever you see "she," "he," "they," or "it" in a sentence, ask yourself, "Could this word point to more than one person or thing?" If yes, the pronoun needs to be replaced with a clear, specific name.
Question 5
David and his father argued because he forgot to pay the bill.
A student wants to revise this sentence so it is clear that David's father forgot to pay the bill. Which revision is BEST?
- David and his father argued because David forgot to pay the bill.
- David and his father argued because his father forgot to pay the bill. (correct answer)
- He and his father argued because his father forgot to pay the bill.
- David and his father argued because they forgot to pay the bill.
Explanation: When a sentence uses a pronoun like "he" or "his," the reader needs to know exactly who that pronoun refers to. This is called pronoun clarity (or clear pronoun reference). If two people of the same gender are in a sentence, a pronoun like "he" or "his" becomes confusing because it could point to either person. Your job in revision questions like this is to find the version that removes all possible confusion.
In the original sentence, "he forgot to pay the bill" is unclear because "he" could mean David or his father. The goal is to revise it so readers know without any doubt that the father forgot. Choice B — "David and his father argued because his father forgot to pay the bill" — accomplishes this perfectly. By replacing the vague "he" with "his father," the sentence points directly to the right person.
Choice A replaces "he" with "David," which actually creates the opposite meaning — it says David forgot, not the father. That's a factual revision error. Choice C introduces "He and his father" at the start, which creates new confusion right away — now "he" is unclear in the subject too, making the whole sentence worse, not better. Choice D uses "they," which implies both David and his father forgot, which changes the meaning entirely and still doesn't clarify who is responsible.
A quick tip: whenever you see a pronoun in a sentence with two people of the same gender, ask yourself, "Could this pronoun mean either person?" If yes, replacing the pronoun with a specific name or relationship word is almost always the right fix.
Question 6
Maria and her sister Rosa went to the store. She bought milk and bread.
The sentence 'She bought milk and bread' is confusing. Which revision BEST makes the reference clear?
- Rosa bought milk and bread, and she was happy about it.
- Maria bought milk and bread at the store that day. (correct answer)
- She and her sister both bought milk and bread together.
- They bought milk and bread, and she paid for them.
Explanation: When a sentence uses a pronoun like "she," "he," or "they," the reader needs to know exactly who that pronoun refers to. This is called pronoun reference clarity. In the passage, "Maria and her sister Rosa went to the store. She bought milk and bread" — the word "she" is confusing because there are two women mentioned, and we don't know which one did the buying.
The best fix is B: "Maria bought milk and bread at the store that day." This revision replaces the unclear pronoun "she" with a specific name, Maria, so there is no confusion. The reader immediately knows who bought the items. This is the cleanest, most direct solution.
Choice A replaces "she" with "Rosa," which does clarify who bought the items, but then immediately introduces a new "she" — "she was happy about it" — which brings the confusion right back. You've traded one unclear pronoun for another.
Choice C uses "She and her sister," which still contains the vague pronoun "she." We still don't know if "she" means Maria or Rosa, so nothing is truly fixed.
Choice D is the most confusing of all — it uses both "they" and "she" together, creating two unclear pronouns instead of one. This makes the sentence harder to understand, not easier.
A helpful strategy: when a question asks you to fix a confusing pronoun, look for the answer that replaces the pronoun with a specific name. That almost always signals the clearest revision.
Question 7
Which of the following sentences has the CLEAREST pronoun reference and does NOT need revision?
- Keiko asked her coworker for help because she didn't understand the form.
- Marco dropped his phone, and it broke when it hit the floor. (correct answer)
- The doctor spoke with the nurse, and then she wrote the report.
- Lin called her friend, but she didn't answer the phone.
Explanation: When you see a question about pronoun reference, ask yourself: who does each pronoun refer to? If a sentence contains two people of the same gender, a pronoun like "she" or "he" can become confusing — the reader cannot be sure which person the pronoun replaces. Clear pronoun reference means each pronoun points to exactly one, unmistakable noun.
Choice B is the clearest example of this. "Marco dropped his phone, and it broke when it hit the floor." Only one person is mentioned (Marco), and "it" refers to "his phone" — there is no other noun it could mean. Every pronoun has one obvious antecedent, so this sentence needs no revision.
The three wrong choices all suffer from unclear pronoun reference. In choice A, both Keiko and her coworker are female, so "she didn't understand the form" is ambiguous — was it Keiko or the coworker who was confused? In choice C, both the doctor and the nurse could be female, so "she wrote the report" leaves the reader guessing which person wrote it. Choice D has the same problem: "Lin called her friend, but she didn't answer" — did Lin not answer, or did the friend not answer? In all three cases, a rewrite (using a name instead of the pronoun) would be needed to clarify meaning.
A useful tip: whenever a sentence has two people of the same gender, underline every pronoun and ask, "Does this pronoun point to only one person?" If there is any doubt, the sentence likely needs revision — and on this exam, that means it is not the correct answer.
Question 8
A student writes: 'Carlos called his brother when he was driving home.' The student wants to make it clear that Carlos was the one driving. Which revision BEST makes the reference clear?
- Carlos called his brother when his brother was driving home.
- Carlos called his brother, and he was driving home at that time.
- When he was driving home, Carlos called him on the phone.
- Carlos called his brother while Carlos was driving home. (correct answer)
Explanation: When a sentence has two people and uses a pronoun like "he" or "his," readers need to know exactly who that pronoun refers to. This is called pronoun reference clarity, and it's what this question is testing. Ask yourself: could a reader be confused about who "he" means?
The original sentence — "Carlos called his brother when he was driving home" — has a problem. The word "he" could refer to either Carlos or his brother. We need a revision that removes that confusion and makes it clear Carlos was driving.
Choice D, "Carlos called his brother while Carlos was driving home," solves the problem directly by replacing the unclear "he" with the name "Carlos." Now there is zero confusion — we know exactly who was behind the wheel. This is the correct answer.
Choice A actually makes things worse by saying "his brother was driving home," which changes the meaning entirely — now it sounds like the brother is the driver, not Carlos.
Choice B keeps the vague pronoun "he" ("he was driving home at that time"), so the same confusion remains. Adding "at that time" doesn't fix the pronoun problem.
Choice C uses both "he" and "him," making things even more confusing. "When he was driving home, Carlos called him" — who is "he"? Who is "him"? A reader still can't be sure.
Study tip: Whenever you see a pronoun like he, she, they, or his in a sentence with two people of the same gender, check whether the pronoun clearly points to one specific person. If it doesn't, replacing the pronoun with the actual name is usually the best fix.
Question 9
A student reads this sentence: 'When James met Mr. Park, he shook his hand.' The student says this sentence is confusing. Is the student correct, and why?
- No, the sentence is clear because 'he' and 'his' always refer to the subject of the sentence, which is James, so there is no confusion.
- Yes, the sentence is confusing because 'he' and 'his' could refer to either James or Mr. Park, making it unclear who shook whose hand. (correct answer)
- No, the sentence is clear because 'he shook his hand' is a common greeting phrase that everyone understands without needing names.
- Yes, the sentence is confusing because 'met' is an irregular verb that makes the time of the action unclear for the reader.
Explanation: When you read a sentence with pronouns like "he" or "his," always ask yourself: who does this pronoun refer to? This is called pronoun reference, and a sentence becomes confusing when a pronoun could logically point to more than one person.
In "When James met Mr. Park, he shook his hand," there are two male people — James and Mr. Park. The pronoun "he" could mean either James or Mr. Park, and "his hand" could belong to either one of them as well. That gives us at least two possible meanings: James shook Mr. Park's hand, OR Mr. Park shook James's hand. Because readers cannot tell which is correct, the student is right to feel confused. Answer B correctly identifies this problem — the ambiguous pronouns make the sentence genuinely unclear.
Answer A is wrong because pronouns do not automatically refer to the subject of the sentence. Grammar rules do not guarantee that "he" means James just because James appears first. Answer C is wrong because even if "shook his hand" is a familiar greeting phrase, that doesn't tell us who did the shaking — the confusion is still real. Answer D is wrong because the verb "met" being irregular has nothing to do with the confusion. The past tense is perfectly clear; the problem is the pronouns, not the verb form.
A helpful strategy: whenever you see multiple people of the same gender in a sentence, check every pronoun carefully. If you can't be 100% sure who the pronoun refers to, the sentence has an ambiguous pronoun reference — a very common grammar topic on beginner ESL exams.
Question 10
Read these two sentences: 'The manager spoke to the new employee. He seemed nervous.' Why is the second sentence unclear, and how should it be fixed?
- It is unclear because 'He' could mean either person; replace 'He' with 'The manager' or 'The new employee' to name who was nervous. (correct answer)
- It is unclear because 'seemed' is a weak verb; replace 'seemed nervous' with 'was very nervous' to make the feeling more direct and powerful.
- It is unclear because the two sentences are too short; combine them into one sentence by adding 'and he seemed nervous' at the end of the first.
- It is unclear because 'nervous' is used incorrectly; replace 'nervous' with the noun 'nervousness' and rewrite the sentence to fix the grammar.
Explanation: When you see a question about unclear sentences, ask yourself: Who or what does the pronoun refer to? A pronoun like "he," "she," or "they" must clearly point to one specific person. When two people of the same gender appear in a sentence, using a pronoun afterward creates confusion — the reader cannot tell which person you mean.
In this example, "The manager spoke to the new employee" introduces two male people. The next sentence, "He seemed nervous," uses "he" — but "he" could describe either the manager or the new employee. The reader is left guessing. The fix is simple: replace "He" with the actual name or title of the person you mean, such as "The manager seemed nervous" or "The new employee seemed nervous." That is exactly what A explains, making it the correct answer.
B is incorrect because "seemed" is not a weak or broken verb — it works perfectly fine here. The problem is not word strength; it is pronoun clarity. C is incorrect because combining the sentences does not solve anything. Writing "The manager spoke to the new employee, and he seemed nervous" still uses the unclear pronoun "he" — the confusion remains. D is incorrect because "nervous" is used correctly as an adjective after "seemed." Changing it to "nervousness" would actually break the grammar, not fix it.
A useful tip: whenever you see a pronoun like "he," "she," or "they," trace it back to find exactly who it refers to. If two people could match, the sentence needs to be rewritten with a specific name or title.
