Correct Answer: C

Rationale: 'Childlike' is an adjective formed by adding the suffix '-like' to the noun 'child.' The suffix '-like' is commonly used to transform a noun into an adjective by indicating a resemblance or characteristic associated with the root noun. Choices A, B, and D do not follow the same pattern. 'Created' is a past participle, 'pointing' is a present participle, and 'suburbanite' is a noun derived from 'suburban.' Therefore, 'Childlike' is the only word where the suffix directly converts the root word into an adjective.

Correct Answer: B

Rationale: The correct answer is B: "Termites are very industrious insects." This is a simple sentence as it contains a subject (termites) and a verb (are) and expresses a complete thought. Choice A is not a simple sentence as it is a dependent clause starting with 'Although' and does not express a complete thought. Choice C is a compound sentence since it consists of two independent clauses joined by the conjunction 'and.' Choice D is a complex sentence with a dependent clause starting with 'Because' and an independent clause.

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.

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: C

Rationale: The word 'shear' means to cut, while 'sheer' in this context means 'complete' or 'unqualified.' The correct spelling in the sentence should be 'sheer.' Choice A, 'peeked' is the correct past tense of 'peek,' meaning to glance quickly or briefly. Choice B, 'through' is the correct preposition to indicate moving in one side and out the other. Choice D, 'scene,' is the correct term for a part of a play or movie, not 'seen,' which is the past participle of 'see.'
