Correct Answer: B

Rationale: The correct answer is B. Parallel structure ensures that items in a series or list are in the same grammatical form. In choice A, 'to run' disrupts the parallel structure since 'hiking' and 'swimming' are gerunds. Choice C similarly breaks the parallelism by using 'to swim' in a different form. Choice D is incorrect because it lacks consistent parallelism, as 'hiking' is not followed by gerunds like 'swimming' and 'running.' Therefore, only choice B maintains proper parallel structure by using gerunds ('hiking,' 'swimming,' and 'running') consistently.

Correct Answer: A

Rationale: The correct answer is A because it correctly uses the second-person narrative voice by addressing the reader as 'you,' directly involving them in the action. Choices B, C, and D use first-person ('I'), third-person singular ('he'), and third-person plural ('they') perspectives, respectively, which do not align with a second-person narrative voice. It is essential to identify the perspective being used in a sentence to determine if it matches the criteria specified in the question.

Correct Answer: C

Rationale: The passage indicates that the writer is a student writing a first draft of a paper. The language used in the passage is informal and lacks precision, suggesting it is not written by a professional in a business environment or a researcher for a scientific journal. The focus on experimenting with hitting a golf ball also aligns more with a student exploring a topic rather than an established author of literature.

Correct Answer: A

Rationale: The correct answer is A. A compound sentence consists of two independent clauses joined by a conjunction or a semicolon. In sentence A, 'The sky is clear' and 'the stars are bright' are two independent clauses joined by the conjunction 'and.'<br>Choice B is a complex sentence as it has a dependent clause ('Although it was late') and an independent clause ('he stayed up').<br>Choice C is a simple sentence with only one subject and one verb.<br>Choice D is a complex sentence with a dependent clause ('While she reads') and an independent clause ('she listens to music').

Correct Answer: B

Rationale: Choice B is the correct answer because it serves as a transition sentence in the paragraph about the Silk Road. It shifts the focus from Chinese silk being a major trade item to the introduction of other important trade items that had a significant impact on the world. This transition indicates a change in the topic being discussed within the paragraph. Choices A, C, and D do not serve as transition sentences. Choice A simply introduces the origin of the Silk Road's name, choice C provides additional information about the network without transitioning to a new topic, and choice D gives a general description of the Silk Road without transitioning to a different aspect of the trade routes.
