The sentence 'The audience was captivated by the speaker's compelling story' implies that the audience:

Correct Answer: C

Rationale: The term 'captivated' in the sentence indicates that the audience was completely engrossed and engaged by the speaker's compelling story. This implies that they were absorbed and highly interested in what was being presented. Choices A, B, and D are incorrect because 'captivated' suggests a positive and attentive reaction from the audience rather than boredom, confusion, or disagreement.

Correct Answer: B

Rationale: "Ironic" and "serious" are antonyms as they have opposite meanings. 'Ironic' refers to something that is contrary to what is expected or intended, while 'serious' indicates something grave or without humor. Therefore, the correct answer is B. Choice A is incorrect because synonyms are words with similar meanings. Choice C is incorrect as homonyms are words that sound the same but have different meanings, which is not the case for 'ironic' and 'serious'. Choice D is also incorrect as there is a relationship between the two words, making B the correct answer.

Correct Answer: C

Rationale: In this sentence, the word 'utter' best fits as it emphasizes the absolute and complete accuracy of the experiment. 'Utter' means total or complete, and in this context, it conveys a sense of total precision. Choices A, B, and D do not carry the same connotation of absolute precision. 'Extreme' and 'remarkable' may imply a high level of precision but not necessarily absolute or complete precision. 'Great' is a more general term that does not specifically emphasize the completeness of the precision required in conducting the experiment.

Correct Answer: B

Rationale: The correct answer is option B, 'I will have finished'. This choice correctly expresses a future event (finishing the project) that will be completed before another future point in time (next week). The future perfect tense 'will have finished' is used to show an action that will be completed before a specified future time. Choice A, 'I will be finishing', is incorrect as it indicates an ongoing action that will still be in progress by next week, which is not the intended meaning. Choice C, 'I am finishing', is incorrect as it indicates a present action that is ongoing, not a future event. Choice D, 'I would finish', is incorrect as 'would' is used for hypothetical situations or polite requests, which is not suitable in this context of a future project completion.

Correct Answer: B

Rationale: The correct spelling for the word 'to submit or agree without protest' is 'acquiesce,' making option B the correct choice. Choice A, 'Accommodate,' refers to providing lodging or fitting in with someone's needs. Choice C, 'Perceive,' means to become aware or conscious of something. Choice D, 'Dilemma,' is a situation requiring a choice between equally undesirable alternatives. Therefore, options A, C, and D are spelled correctly but are not the correct answer based on the definition provided in the question.
