Which of the following sentences has correct pronoun-antecedent agreement?

Correct Answer: C

Rationale: Sentence C correctly maintains the pronoun-antecedent agreement. In this sentence, the antecedent is 'number of people,' and the pronoun 'it' is used to refer back to this antecedent. The singular pronoun 'it' matches the singular antecedent 'number,' making the sentence grammatically correct. Choice A is incorrect because it uses the plural pronoun 'they' to refer back to the singular antecedent 'storm.' Choice B is incorrect as it uses the plural pronoun 'they' to refer back to the singular antecedent 'each of the cars.' Choice D is incorrect because it uses the singular pronoun 'he or she' to refer back to the plural antecedent 'many people.' This creates a lack of agreement between the pronoun and its antecedent.

Correct Answer: C

Rationale: The apostrophe in 'mountain's' is used incorrectly. The word should be 'mountains' without the apostrophe because it is a plural noun, not possessive. The other choices (A, B, D) have the correct usage of punctuation marks and do not contain errors related to punctuation.

Correct Answer: C

Rationale: Sentence C correctly maintains the pronoun-antecedent agreement. In this sentence, the antecedent is 'number of people,' and the pronoun 'it' is used to refer back to this antecedent. The singular pronoun 'it' matches the singular antecedent 'number,' making the sentence grammatically correct. Choice A is incorrect because it uses the plural pronoun 'they' to refer back to the singular antecedent 'storm.' Choice B is incorrect as it uses the plural pronoun 'they' to refer back to the singular antecedent 'each of the cars.' Choice D is incorrect because it uses the singular pronoun 'he or she' to refer back to the plural antecedent 'many people.' This creates a lack of agreement between the pronoun and its antecedent.

Correct Answer: A

Rationale: The root word 'corp' is related to the body as it comes from the Latin word 'corpus,' meaning body. Words like 'corporal' and 'corporation' are derived from this root, linking them to the body in some manner. Choices B, C, and D are incorrect. 'Auto' relates to self or automatic, 'man' pertains to human or hand, and 'bio' is associated with life or living organisms, none of which directly signify the body.

Correct Answer: B

Rationale: The subject 'employer' in sentence B agrees with the singular verb 'decided.' In subject-verb agreement, singular subjects need singular verbs, while plural subjects need plural verbs. The use of 'decided' correctly pairs with the singular subject 'employer' in this sentence. Choice A is incorrect as the subject 'Akhal-Teke horse breed' is singular and should be paired with the singular verb 'has,' not 'have.' Choice C is incorrect because the verb 'play' does not agree with the plural subject 'mountains'; it should be 'play host' or 'are home to.' Choice D is incorrect as 'Each of the storm chasers' is a singular subject and should be paired with the singular verb 'decides,' not 'decide.'

Correct Answer: B

Rationale: The correct answer is B: 'dollars.' 'Bucks' is a slang term for dollars. The use of 'bucks' in this sentence is informal and colloquial compared to the other word choices, making it the slang word in the sentence. 'Cost,' 'steep,' and 'tag' are all standard English words that are not considered slang in this context.

Correct Answer: C

Rationale: A complex sentence has one independent clause and at least one dependent clause connected by a subordinating conjunction or a relative pronoun. In choice C, the sentence 'Because the distance between stars in the galaxy is far greater than the distance between planets' is a dependent clause introduced by the subordinating conjunction 'Because,' while the rest of the sentence 'interstellar travel is expected to be an even bigger challenge than interplanetary exploration' forms the independent clause. This combination of an independent clause and a dependent clause makes choice C a complex sentence. Choices A, B, and D do not contain both an independent and dependent clause connected in the way that choice C does, thus they do not qualify as complex sentences.

Correct Answer: C

Rationale: The comma (,) is used to separate the introductory clause 'After a twelve-hour workday' from the main clause 'James was exhausted when he heard the news.' This punctuation correctly indicates the relationship between the two clauses without interrupting the flow of the sentence. Choice A (.), a period, would create two separate sentences, which is not appropriate in this context. Choice B (;) is too strong of a pause and semicolons are typically used to connect closely related independent clauses. Choice D (-) is an em dash, which is used to set off an abrupt break or interruption in the sentence, not to separate an introductory clause from the main clause.

Correct Answer: C

Rationale: Option C is the correct answer because it disrupts the flow of the sentence and introduces unnecessary information. The phrase 'over the years since 1958' is irrelevant in this context and does not contribute to the intended meaning of the sentence. The sentence is focused on the recent changes to the pension, not its historical evolution. Choices A, B, and D provide clear and concise ways to revise and combine the underlined portion of the sentences, maintaining a logical and relevant sentence structure.
