Rationale: The US imports most of its silicone chips from Japan and China, indicating that the silicone chips are being brought into the US from these countries. 'Imports' refers to the act of bringing goods or services into one country from another, which accurately describes the scenario described in the question. The other choices are incorrect: 'Deports' means expelling individuals from a country, 'Exports' mean sending goods to another country, and 'Reports' mean providing information or data.

Correct Answer: D

Rationale: The term 'insidious' typically describes something that occurs gradually and subtly, often without being noticed until it has become more serious or established. Therefore, the development of the disease being insidious suggests that it was gradual, aligning best with the meaning of the word in this context. Choice A, 'momentous,' means significant or important, which is opposite in meaning to insidious. Choice B, 'sudden,' indicates something happening quickly and unexpectedly, contrary to the gradual nature of an insidious development. Choice C, 'innocuous,' means harmless or not likely to cause harm, which does not accurately reflect the negative and harmful connotation associated with an insidious disease development.

Correct Answer: C

Rationale: The word 'm©lange' refers to a mixture or medley of different elements, which perfectly fits the description of someone who listens to various music genres. It implies diversity in their collection, covering a broad range of styles from punk rock to classical music. Choice A, 'Theoretical,' does not relate to music collections and is more aligned with concepts and hypotheses. Choice B, 'Relevant,' does not capture the idea of a varied music collection. Choice D, 'Cacophony,' refers to a harsh, discordant mixture of sounds, which does not represent a music collection with a variety of genres.

Correct Answer: A

Rationale: The correct answer is A: 'He is a legal resident of the United States.' In this sentence, 'legal' is used to describe the type of resident he is, making it an adjective. The other choices use 'legal' as part of a noun phrase or an adverbial phrase, not as an adjective. Choice B uses 'legal' to describe the type of action, making it a noun adjunct. Choice C uses 'legal' to describe the legality of the action, making it part of an adjectival phrase. Choice D uses 'legal' to describe the manner in which he acted, making it an adverb.

Correct Answer: B

Rationale: In this sentence, the correct option is 'had run' as it is the past perfect tense, which is used to indicate an action completed before another past action. The sentence structure requires the past perfect form to show that the running occurred before catching up with the man. 'Ran' (choice A) is in simple past tense and does not convey the sequence of events correctly. 'Chased' (choice C) is the simple past tense of the verb 'chase' and does not align with the past perfect tense needed in the sentence. 'Drove' (choice D) is incorrect as it refers to using a vehicle to pursue someone, whereas the context of the sentence indicates running on foot.
