Correct Answer: D

Rationale: The correct answer is 'Anthropology.' This term is derived from the Greek words 'anthropos' meaning 'human' and 'logos' meaning 'study.' Therefore, Anthropology refers to the study of humans. Choice A, 'Biology,' is the study of living organisms, not specifically focused on humans. Choice B, 'Philanthropy,' refers to the practice of giving and helping others. Choice C, 'Anthropomorphism,' is the attribution of human characteristics to non-human entities.

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: Option C is the correct answer as it uses introductory punctuation correctly by placing a comma after the introductory clause 'Since we only have ten minutes.' Commas are used to separate introductory phrases or clauses from the main clause in a sentence. Option A is incorrect as it lacks the necessary comma after the introductory phrase. Option B uses a semicolon, which is not typically used in this context. Option D uses a colon, which is not appropriate for introducing the following clause in this sentence structure.

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: 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.
