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 correct answer is A: 'Performed by one person.' 'Unilateral' means something done by one person or group without the agreement of another. Choice B is incorrect as it suggests the opposite of what 'unilateral' means. Choice C is incorrect as it does not capture the essence of 'unilateral.' Choice D is incorrect as it is not directly related to the definition of 'unilateral.'

Correct Answer: A

Rationale: The subject 'Neither' is singular, so the correct verb form to use is 'is.' In this sentence, 'boys' is part of a prepositional phrase 'of the boys' and does not affect the verb agreement. 'Are' (choice B) is plural and does not match the singular subject. 'Were' (choice C) is past tense and not suitable for the present context. 'Be' (choice D) is an infinitive form and does not agree with the subject.

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: 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.
