Which of the following sentences correctly uses subject-verb agreement?

Correct Answer: B

Rationale: The correct answer is B because it maintains subject-verb agreement. In this sentence, 'she is' agrees with 'the lead scientist,' and 'does' agrees with 'she.' Choices A, C, and D have subject-verb agreement errors. In choice A, 'write' should be 'writes' to match the singular subject 'The lead scientist,' and 'does' should be 'do' to match the plural 'scientists in the group.' Choice C also has the same subject-verb agreement error as A. In choice D, 'do the research' should be 'does the research' to match the singular 'every scientist in the group.'

Correct Answer: A

Rationale: The correct answer is A: 'To go around.' Circumvent means to find a way around an obstacle or to avoid something by cleverness or deception. Choice B, 'To go under,' is incorrect as circumvent does not involve going under something. Choice C, 'To come near,' is incorrect as circumvent does not mean to approach or get close to something. Choice D, 'To come through,' is incorrect as circumvent does not involve passing through something.

Correct Answer: D

Rationale: In this sentence, 'increasingly' is functioning as an adverb. Adverbs modify verbs, adjectives, or other adverbs to describe the manner, degree, or frequency of an action. In this case, 'increasingly' describes how the difficulty of the hike was growing as we approached the mountain top. Choice A, 'Adjective,' is incorrect as adjectives modify nouns or pronouns, not verbs. Choice B, 'Interjection,' is also incorrect because interjections are words used to express strong emotions or sentiments, not to describe actions or qualities. Choice C, 'Verb,' is incorrect as 'increasingly' is not a verb; it does not express an action or state of being.

Correct Answer: D

Rationale: The correct answer is 'consequently.' In this sentence, 'consequently' is used to show the result of their late arrival, leading to them missing the wedding. 'Although' (choice A) is incorrect because it suggests a contrast rather than a cause-effect relationship. 'Conversely' (choice B) is also incorrect as it indicates a contrasting idea. 'Unless' (choice C) introduces a condition, which doesn't fit the context of the sentence. Therefore, 'consequently' best connects the delay to missing the wedding.

Correct Answer: A

Rationale: The term 'intraocular' is derived from 'intra-' meaning within and 'ocular' referring to the eyes. Therefore, 'intraocular' means within the eyes. Choice A is correct. Choices B, C, and D are incorrect as they do not accurately reflect the meaning of 'intraocular' based on the analysis of word parts.
