- Which revision best corrects the vague pronoun 'it'?
Answer: The news report said that a storm is approaching.
When you encounter a question about vague pronouns, focus on identifying what the pronoun refers to and whether that reference is clear to readers. A vague pronoun creates confusion because it's unclear what noun the pronoun is replacing.
In the original sentence, "it" is vague because there's no clear noun for it to reference. The pronoun "it" appears to refer to "the news report," but grammatically, it's floating without a proper antecedent, making the sentence awkward and unclear.
Choice B correctly eliminates the vague pronoun by making "The news report" the subject of the sentence. This creates a clear, direct statement where the subject performs the action of saying something. The sentence flows naturally and leaves no doubt about what is doing the "saying."
Choice A simply moves the vague pronoun "it" to the beginning, but doesn't solve the fundamental problem—"it" still lacks a clear antecedent. Choice C compounds the issue by creating a comma splice (incorrectly joining two independent clauses with just a comma) while keeping the vague "it" at the end. Choice D attempts to fix the problem with "According to what it said" but still contains the problematic vague pronoun "it."
When you see pronoun questions on the GED, always ask yourself: "What specific noun does this pronoun replace?" If you can't point to a clear answer, look for the revision that either provides a clear antecedent or eliminates the pronoun entirely by using the actual noun instead.
- Which of the following correctly revises the sentence above?
Answer: The lead scientist and the project manager will give their final report on Monday.
When you encounter pronoun agreement questions, you need to identify what the pronoun refers to and ensure they match in number (singular or plural).
In this sentence, the pronoun "his" refers back to "the lead scientist and the project manager." When two subjects are joined by "and," they create a compound subject that is plural and requires a plural pronoun. Since we have two people giving a report together, the correct pronoun is "their."
Option B correctly uses "their" to match the plural compound subject. This makes logical sense—two people are collaborating on one shared report.
Option A keeps the original error, using the singular "his" with a plural subject. This is grammatically incorrect because the pronoun doesn't agree in number with what it references.
Option C substitutes "her" for "his," but this still creates the same agreement error—a singular pronoun with a plural subject. The gender change doesn't fix the fundamental number disagreement.
Option D uses "its," which is wrong for two reasons: first, it's singular when you need plural, and second, "its" refers to things or animals, not people.
Study tip: When you see compound subjects joined by "and," they're almost always plural and need plural pronouns like "their," "they," or "them." Watch out for this pattern—it's a common trap where test makers hope you'll focus on the closest noun rather than recognizing the full compound subject.
- Which of the following correctly revises the sentence above?
Answer: Each of the new employees must submit his or her paperwork by Friday.
This question tests subject-pronoun agreement, specifically when dealing with indefinite pronouns like "each." When you encounter sentences beginning with "each of," pay close attention to whether the subject is singular or plural, as this determines the correct pronoun.
The subject here is "each," which is always singular, even when followed by a plural noun like "employees." Since "each" refers to individual people considered one at a time, you need a singular pronoun that can refer to people of any gender.
Choice D is correct because "his or her" provides a singular pronoun that appropriately refers back to the singular subject "each" while acknowledging that the employees could be of any gender. This maintains proper grammatical agreement.
Choice A repeats the original error by using "their," a plural pronoun, with the singular subject "each." While "their" is increasingly accepted in informal speech as a gender-neutral option, traditional grammar rules still require singular pronouns with singular subjects on standardized tests.
Choice B uses "its," which is grammatically singular but refers to things, not people. Using "its" to refer to employees is inappropriate and dehumanizing.
Choice C uses "them," which is not only plural (creating the same agreement error as choice A) but also uses the wrong form entirely—"them" is an object pronoun, not a possessive pronoun needed before "paperwork."
Remember: indefinite pronouns like "each," "everyone," "someone," and "anybody" are always singular and require singular pronouns, even when they logically refer to multiple people.
- Which sentence contains an ambiguous pronoun reference?
Answer: After the dog chased the cat, it took a long nap.
When you encounter questions about pronoun reference, you're being tested on clarity in writing. A pronoun should clearly refer to one specific noun (its antecedent). If a pronoun could refer to multiple nouns, it creates ambiguous reference that confuses readers.
In choice B, "After the dog chased the cat, it took a long nap," the pronoun "it" is ambiguous because it could refer to either "the dog" or "the cat." Since both animals are possible subjects for taking a nap, readers can't determine which one the writer means. This unclear reference makes the sentence confusing and demonstrates poor writing technique.
Choice A works correctly because "he" clearly refers back to "the mechanic" – there's only one person mentioned who could have done the job. Choice C is unambiguous because "its" refers specifically to "the book," and "which was on the table" is a clear modifier describing the book's location. Choice D contains no ambiguity since "their" obviously refers to "the students" as a group, and "the project" is clearly what they want an extension for.
The other choices demonstrate proper pronoun usage where each pronoun has one clear, logical antecedent that readers can easily identify.
Remember this strategy: When you see pronouns like "it," "they," "this," or "that," trace them back to their antecedents. If you can identify two or more possible nouns the pronoun might refer to, you've found an ambiguous reference error. Clear writing always makes pronoun relationships obvious to readers.
- Which revision best corrects the vague pronoun reference in the sentences?
Answer: The company's security policy update caused confusion among employees.
When you encounter pronoun reference questions, you're looking for clarity about what each pronoun refers to. Vague pronouns like "this" or "it" can confuse readers when they could refer to multiple things or when their antecedent isn't clear.
In the original sentences, "this" in the second sentence creates confusion because it's unclear what exactly caused the confusion—was it the update itself, the policy, or something else about the situation?
Answer choice C eliminates the vague pronoun entirely by combining the sentences and clearly stating what caused the confusion: "The company's security policy update." This revision is direct, clear, and leaves no ambiguity about what led to employee confusion.
Looking at the wrong answers: Choice A simply moves "this" into the same sentence but doesn't fix the vague reference—"this" still lacks a clear antecedent. Choice B improves clarity somewhat by specifying "policy update," but the phrase "This policy update" still begins with a vague pronoun reference. Choice D actually makes the problem worse by using both "There was" (which creates wordiness) and "this" without any clear reference to what "this" means.
When you see pronoun reference questions on the GED, look for the revision that either provides a clear antecedent for the pronoun or eliminates the vague pronoun altogether by restating the specific noun or concept. The clearest writing often avoids potentially confusing pronouns by being more specific with word choice.
- Which sentence uses pronouns correctly?
Answer: Neither the supervisor nor the employees were happy with their bonuses.
When you encounter pronoun agreement questions involving compound subjects with "neither...nor," you need to consider two key rules: subject-verb agreement and pronoun-antecedent agreement.
The correct answer is A because it follows both rules properly. With "neither...nor" constructions, the verb and pronoun agree with the closer subject. Since "employees" (plural) comes after "supervisor" (singular), the verb should be "were" (plural) and the pronoun should be "their" (plural). The sentence correctly uses both the plural verb "were" and the plural pronoun "their."
Option B is incorrect because it uses "his or her," which refers to a singular antecedent, but the closer subject "employees" is plural. The pronoun should match the plural "employees," not the singular "supervisor."
Option C makes the same error as B, using the singular "her" instead of the required plural pronoun. Additionally, "her" assumes the supervisor is female, which creates an unwarranted assumption about gender.
Option D contains a subject-verb disagreement. While it correctly uses the plural pronoun "their," it incorrectly uses the singular verb "was." Since "employees" is the closer subject in this "neither...nor" construction, both the verb and pronoun must be plural.
Remember this pattern: in "neither...nor" sentences, always make your verb and pronouns agree with whichever subject comes second. This rule will help you avoid the common trap of trying to make everything singular just because "neither" sounds singular.
- Which of the following correctly revises the sentence for formal usage?
Answer: Whom did the company choose for the promotion?
This question tests your understanding of when to use "who" versus "whom" in formal writing. The key is determining whether the pronoun functions as a subject or an object in the sentence.
To decide between "who" and "whom," rearrange the question into a statement and see what role the pronoun plays. "The company chose [someone] for the promotion." Since "someone" receives the action of being chosen, it's the direct object of the verb "chose." When a pronoun serves as an object (direct object, indirect object, or object of a preposition), you must use "whom" in formal writing.
Choice A is correct because "whom" properly functions as the direct object in this sentence. The formal revision requires this objective case pronoun.
Choice B keeps the original "who," which is actually the subjective case. While this might sound natural in casual conversation, it's grammatically incorrect in formal writing since the pronoun serves as the object, not the subject.
Choice C uses "whoever," which is completely inappropriate here. "Whoever" means "any person who" and would create a nonsensical meaning: "Any person who did the company choose for the promotion?"
Choice D uses "whose," the possessive form of "who." This creates an incomplete and meaningless sentence since "whose" indicates ownership and requires a noun to follow it.
Study tip: When choosing between "who" and "whom," substitute "he/him" or "she/her" in the rearranged statement. If "him" or "her" fits, use "whom." If "he" or "she" fits, use "who."
- Which of the following correctly revises the sentence above?
Answer: The supervisor assigned the new task to me and my colleague.
This question tests your understanding of pronoun case, specifically when to use "I" versus "me" in compound objects. When you encounter pronouns paired with other nouns after prepositions like "to," you need to determine which pronoun form is grammatically correct.
The key is recognizing that "my colleague and I" serves as the object of the preposition "to." Objects always require the objective case pronoun "me," not the subjective case "I." You can test this by removing the other person from the sentence: "The supervisor assigned the new task to me" sounds correct, while "The supervisor assigned the new task to I" clearly sounds wrong.
Answer choice A correctly uses "me and my colleague," placing both words in the proper objective case. The order "me and my colleague" is also more courteous than "my colleague and me," following the convention of putting others before yourself.
Answer choice B uses "myself," which is incorrect because reflexive pronouns like "myself" should only be used when the subject and object refer to the same person, or for emphasis.
Answer choice C repeats the original error by using "I" instead of "me" as the object of the preposition.
Answer choice D, while grammatically correct, unnecessarily changes the sentence to passive voice, making it wordier and less direct than the original active construction.
Study tip: When checking pronoun case in compound phrases, temporarily remove the other person from the sentence. This makes it easier to hear whether "I" or "me" sounds correct in context.
- Which revision best corrects the vague pronoun 'they'?
Answer: The community center offers free computer classes for seniors.
When you encounter questions about pronoun reference, you're being tested on clarity and precision in writing. A vague pronoun is one where the reader can't easily identify what the pronoun refers to. In this sentence, "they" doesn't have a clear antecedent—there's no specific group of people mentioned that "they" could logically refer to.
The best revision eliminates the vague pronoun entirely by making the community center itself the subject of the sentence. Choice A does exactly this: "The community center offers free computer classes for seniors." This creates a clear, direct sentence where the subject (community center) performs the action (offers classes). The meaning is immediately obvious to any reader.
Looking at the incorrect choices: Choice B simply replaces "they" with "them," which is still vague—"them" has the same reference problem as "they." Choice C keeps the original vague "they" and only moves the location phrase, so the pronoun issue remains completely unresolved. Choice D also preserves the problematic "they" while rearranging the sentence structure, making it both vague and awkward.
For pronoun questions on the GED, always ask yourself: "What specific noun does this pronoun refer back to?" If you can't point to a clear antecedent in the sentence or immediate context, look for the revision that either provides a clear antecedent or eliminates the vague pronoun altogether. The clearest writing often uses specific nouns rather than pronouns when there's any chance of confusion.
- Which of the following correctly revises the sentence above?
Answer: He and his brother started a successful catering business.
This question tests your understanding of subject pronouns versus object pronouns, a common area of confusion in formal writing. When you encounter pronouns used as the subject of a sentence, you need to determine which form is grammatically correct.
The key is identifying that "him and his brother" serves as the subject of the sentence - they are performing the action of starting a business. Subject pronouns (I, he, she, we, they) are used when the pronoun is doing the action, while object pronouns (me, him, her, us, them) are used when the pronoun is receiving the action. Since these pronouns are the ones starting the business, you need the subject form "he."
Answer C is correct because "He and his brother started a successful catering business" uses the proper subject pronoun "he." This follows standard grammar rules for compound subjects.
Answer A is wrong because "him" is an object pronoun, not a subject pronoun. You wouldn't say "Him started a business" by itself. Answer B makes the same error - simply switching the order doesn't fix the pronoun case problem. "Him" is still incorrect as a subject. Answer D uses "himself," which is a reflexive pronoun. Reflexive pronouns are only used when the subject is performing an action on itself, which isn't the case here.
Here's a helpful test: remove the other person from the sentence and see if it sounds right. "Him started a business" sounds wrong, but "He started a business" sounds correct. This simple trick will help you choose the right pronoun form every time.
- Which of the following correctly revises the sentence for formal writing?
Answer: Everybody should remember to turn in his or her assignment before leaving.
This question tests pronoun-antecedent agreement in formal writing, specifically how to handle indefinite pronouns like "everybody." In formal writing, you need to ensure that pronouns match their antecedents in both number and gender appropriateness.
The correct answer is C because "everybody" is grammatically singular, even though it refers to multiple people. In formal writing, singular indefinite pronouns like "everybody," "everyone," "somebody," and "anyone" should be paired with singular pronouns. Since we don't know the gender of the people being referenced, "his or her" is the traditional formal solution that maintains grammatical correctness while being inclusive.
Looking at the wrong answers: A uses "their" with "everybody," which creates a number disagreement (singular antecedent with plural pronoun). While this usage is increasingly accepted in casual speech and even some formal contexts, traditional formal writing still requires the singular pairing. B contains "them assignments," which is nonstandard English—"them" cannot modify a noun like an adjective. D uses "there," which is completely incorrect since "there" indicates location, not possession; you need a possessive pronoun here.
For the GED, remember that formal writing questions typically test traditional grammar rules rather than evolving casual usage. When you see indefinite pronouns like "everybody" or "someone," look for singular pronoun matches. If gender is unknown, "his or her" is the safest formal choice, though be aware that "their" is gaining acceptance in modern writing.
- Which sentence uses 'who' or 'whom' correctly?
Answer: The manager whom the team respects is retiring soon.
When you encounter questions about "who" versus "whom," you're dealing with pronoun case - specifically, whether the pronoun functions as a subject or object in the sentence.
The key test is substitution: replace the pronoun with "he/she" (subject) or "him/her" (object). If "he" or "she" fits, use "who." If "him" or "her" fits, use "whom."
Choice A is correct because "whom" functions as the direct object of the verb "respects." Test it: "The team respects him" works perfectly, confirming that "whom" is the right choice.
Choice B incorrectly uses "who" after the preposition "for." Prepositions always take objects, so you need "whom" here. You wouldn't say "for she" - you'd say "for her," which confirms "whom" is needed.
Choice C makes the opposite error, using "whom" as the subject of "was promoted." Test it: "Him was promoted" sounds wrong because you need the subject form "he," which means the sentence needs "who."
Choice D has a word order issue that disguises the pronoun case error. Rearrange it to normal order: "We should contact who about this issue." Since "contact" needs a direct object and you'd say "contact him" (not "contact he"), this should be "whom."
Remember this quick trick: if you can substitute "him/her" or the pronoun follows a preposition, use "whom." If you can substitute "he/she" or the pronoun is doing the action, use "who."
- Which of the following correctly revises the sentence above?
Answer: Several of the committee members expressed their concerns about the budget.
This question tests pronoun-antecedent agreement, a fundamental grammar rule where pronouns must match their antecedents in number, gender, and person. When you encounter sentences with pronouns, always identify what noun the pronoun refers to and check if they agree.
The correct answer is A because "several of the committee members" is a plural subject referring to multiple people. The pronoun must be plural ("their") and the noun should also be plural ("concerns") to properly match the plural subject.
Let's examine why the other options fail: Option B is the original sentence with a clear error—"his" is singular, but it refers to "several...members," which is plural. This creates a mismatch. Option C uses "its," which refers to things rather than people, making it inappropriate for committee members who are people. Option D contains two errors: "it's" is a contraction meaning "it is" rather than the possessive pronoun needed here, and like option C, "it" incorrectly treats the people as objects rather than individuals.
Pay special attention to phrases beginning with "several," "many," "few," or "some"—these signal plural subjects that require plural pronouns. Also watch for the difference between "its" (possessive) and "it's" (contraction), and remember that "its" should only refer to things, not people. When proofreading, always trace each pronoun back to its antecedent to ensure they match in number and appropriateness.
- In which sentence is the pronoun used correctly?
Answer: Give the files to whoever is at the front desk.
When you encounter pronoun questions on the GED, you need to determine whether to use subjective pronouns (who, whoever) or objective pronouns (whom, whomever) based on the pronoun's function in its own clause.
The correct answer is C because "whoever" serves as the subject of the clause "whoever is at the front desk." Since "whoever" performs the action "is," you need the subjective form. The entire clause "whoever is at the front desk" acts as the object of the preposition "to," but within that clause, "whoever" is the subject.
Let's examine why the other options are incorrect. Choice A uses "who" incorrectly because it should be "whom" - the pronoun is the object of the preposition "with" in "I spoke with [whom]." Choice B incorrectly uses "whom" when it should be "who" because the pronoun is the subject of the clause "who lives next door," performing the action of living. Choice D uses "who" incorrectly because it should be "whom" - the pronoun is the direct object in "the team chose [whom] as captain."
Here's a reliable strategy: substitute "he/she" or "him/her" into the clause. If "he" or "she" sounds right, use "who" or "whoever." If "him" or "her" sounds right, use "whom" or "whomever." For example, in choice C, you'd say "he is at the front desk" (not "him is"), confirming that "whoever" is correct.
- Which of the following correctly revises the sentence above?
Answer: If a person wants to succeed in this field, he or she must be willing to learn continuously.
This question tests pronoun-antecedent agreement, a fundamental grammar rule that requires pronouns to match their antecedents in number, gender, and person. When you encounter sentences with pronouns, always identify what noun the pronoun refers back to and check if they agree.
The correct answer is D because "he or she" properly refers back to the singular noun "a person." Since "person" is singular and could refer to either gender, the traditional formal solution is to use "he or she" to maintain both grammatical correctness and inclusivity.
Let's examine why the other options fail: Option A creates a pronoun-antecedent disagreement because "they" is plural while "a person" is singular. Though this usage is increasingly common in casual speech, it remains grammatically incorrect in formal writing contexts like the GED. Option B incorrectly uses "it" to refer to a person, which is inappropriate since "it" refers to objects or animals, not people. Option C shifts from third person ("a person") to second person ("you"), creating an inconsistent point of view within the same sentence.
For GED success, remember that formal writing still requires strict pronoun-antecedent agreement. When you see singular nouns like "person," "student," or "worker," look for singular pronouns in the answer choices. While "they" as a singular pronoun is gaining acceptance in modern usage, standardized tests typically expect traditional grammatical rules, so "he or she" remains the safest choice for singular gender-neutral references.
- Which sentence is grammatically correct?
Answer: We citizens must stay informed about the candidates and them.
This question tests your understanding of pronoun case—specifically when to use subject pronouns (like "we" and "they") versus object pronouns (like "us" and "them"). The key is identifying each pronoun's grammatical role in the sentence.
Let's break down the sentence structure: "_____ citizens must stay informed about the candidates and _____." The first blank needs a pronoun that works with "citizens" as the subject of the sentence. The second blank needs a pronoun that serves as the object of the preposition "about."
For the first position, you need a subject pronoun. Even though "citizens" follows the pronoun, the entire phrase "we citizens" acts as the subject. You can test this by removing "citizens"—"We must stay informed" sounds correct, while "Us must stay informed" clearly doesn't work.
For the second position, the pronoun is part of a compound object following "about." Just as you'd say "about the candidates," you need the object form "them," not the subject form "they."
Choice A is wrong because "us" incorrectly uses the object form in the subject position. Choice B fails because "they" incorrectly uses the subject form in the object position. Choice C makes the first error from A, using "us" as the subject. Only choice D correctly uses "we" (subject pronoun) in the subject position and "them" (object pronoun) in the object position.
Study tip: When pronouns appear in compound phrases, mentally remove the other parts and see if the pronoun alone sounds correct in that position.
- Which of the following correctly revises the sentence above?
Answer: The committee needs to decide whom they should nominate.
This question tests your understanding of when to use "who" versus "whom" in a sentence. The key is determining whether the pronoun functions as the subject or object of the verb.
To decide between "who" and "whom," look at how the pronoun functions in its own clause. In the phrase "who/whom they should nominate," the pronoun serves as the direct object of the verb "nominate" — the committee is nominating someone. Since "whom" is the objective form of the pronoun (like "him" or "her"), it's the correct choice here. You can test this by rephrasing: "they should nominate him" sounds right, while "they should nominate he" doesn't.
Choice A uses "who," which is the subjective form (like "he" or "she"). This would be correct if the pronoun were the subject, such as in "who should nominate them," but here it's the object being nominated.
Choice B, "whose," is a possessive pronoun indicating ownership, like "whose car" or "whose idea." It doesn't make sense in this context since we're not talking about possession.
Choice D, "whomever," might seem tempting since it's also objective, but "whomever" is used differently — typically after prepositions or in more complex constructions. "Whom" is the standard choice for direct objects like this.
Remember this simple test: if you can substitute "him/her" in the pronoun's position and it sounds natural, use "whom." If "he/she" fits better, use "who."
- Which revision eliminates the ambiguity in the sentence above?
Answer: Michael said to his uncle, "My flight is delayed."
When you encounter sentences with unclear pronoun references, you need to identify which nouns the pronouns could reasonably refer to, creating confusion for readers. In this sentence, "his" appears twice but could refer to either Michael or his uncle, making it ambiguous whose flight was delayed.
The correct answer is C because it eliminates ambiguity by using direct quotation with first-person pronouns. When Michael says "My flight is delayed," there's no confusion about whose flight is being discussed—the speaker (Michael) clearly identifies himself as the owner of the delayed flight.
Let's examine why the other options fail. Choice A still contains the problematic pronoun "his" in "his flight," so the ambiguity remains—we still don't know definitively whether it's Michael's or his uncle's flight. Choice B improves clarity somewhat by establishing that Michael's flight was delayed first, but the sentence structure is awkward and less direct than the correct answer. Choice D simply rearranges the original sentence without addressing the pronoun ambiguity—"his flight" still creates the same confusion about ownership.
When you see questions about ambiguous pronouns on the GED, look for revisions that either replace pronouns with specific nouns or use direct quotation to clarify the speaker's perspective. Direct quotes with first-person pronouns ("I," "my," "me") are often the clearest way to eliminate pronoun confusion because they establish a clear speaker-subject relationship.
- Which sentence uses pronouns correctly according to the rules of formal grammar?
Answer: The last person to leave the building was he.
This question tests your understanding of pronoun case, specifically when to use subjective pronouns (like "he") versus objective pronouns (like "him"). The key is identifying what role the pronoun plays in the sentence structure.
In sentences with linking verbs like "was," the noun or pronoun that follows should be in the subjective case because it renames or identifies the subject. Think of it as an equation: "The last person" = "he." When you use a linking verb, both sides of the equation should be in the same case. Since "person" is the subject, the pronoun that renames it should also be subjective.
Answer B is correct because "he" is the proper subjective pronoun form. The sentence structure "The last person to leave the building was he" follows formal grammar rules for linking verbs.
Answer A uses "him," which is the objective case and grammatically incorrect after the linking verb "was." This is probably the most tempting wrong answer because "him" sounds more natural in casual speech, but formal grammar requires the subjective case.
Answer C compounds the error by using "him" in a construction that also calls for the subjective case. The phrase "It was him who..." should be "It was he who..." for the same reason.
Answer D presents the same case error as A and C, just in question form. Even when asking a question, the pronoun after a linking verb should remain subjective.
Remember this test: if you can substitute "he" or "she" naturally, use the subjective form. If "him" or "her" fits better, use the objective form.
- Which revision best corrects the vague pronoun reference in the sentence?
Answer: The candidate was a great public speaker, a skill that helped him win the election.
Pronoun reference questions test whether pronouns clearly point to specific nouns. When pronouns like "which," "this," or "it" could refer to multiple things or entire ideas, the sentence becomes vague and confusing.
In the original sentence, "which" creates ambiguity because it could refer to either "speaker" or the entire concept of being a great public speaker. The best revision eliminates this vague pronoun entirely while maintaining the logical connection between the candidate's speaking ability and electoral success.
Choice C correctly removes the problematic pronoun by restructuring the sentence with an appositive phrase: "a skill that helped him win the election." Here, "skill" clearly refers to public speaking, and "that" unambiguously points to "skill." This creates a clear, direct relationship without any confusing pronoun references.
Choice A simply rearranges the same vague "which" reference. The pronoun still doesn't clearly point to a specific noun, making this revision equally problematic as the original.
Choice B replaces "which" with "this," but "this" is just as vague since it refers to the entire previous clause rather than a specific noun. Demonstrative pronouns like "this" often create the same reference problems as relative pronouns.
Choice D introduces a new error with "it." The pronoun "it" has no clear antecedent in the sentence, creating an even more confusing construction where the subject of "helped" is unclear.
When you encounter pronoun reference questions, look for revisions that either replace vague pronouns with specific nouns or restructure sentences to eliminate ambiguous pronoun references entirely.
