The rain will CEASE at sundown.

Correct Answer: C

Rationale: The word 'cease' means to stop or come to an end. In the given sentence, it is implied that the rain will stop at sundown, not decrease, begin, or increase. Therefore, the correct option is 'Stop.' 'Decrease' means to become smaller or less, which doesn't fit the context. 'Begin' means to start, which is the opposite of what is stated. 'Increase' means to become or make greater in amount, which is also contrary to the statement.

Correct Answer: A

Rationale: The word 'labile' is used to describe something that is constantly changing or easily altered. Therefore, the best synonym for 'labile' is 'extremely changing.' Choice B, 'suicidal,' is incorrect as it does not relate to the meaning of 'labile.' Choice C, 'rapidly changing,' is close but not as precise as 'extremely changing.' Choice D, 'with a high fever,' is completely unrelated to the meaning of 'labile.'

Correct Answer: B

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

Correct Answer: B

Rationale: The correct answer is 'despite.' 'Despite' is used to indicate a contrast between attending the party and the dislike for the host. 'Because of' (choice A) is incorrect as it would imply that she attended the party specifically because of her dislike for the host. 'In spite of' (choice C) has the same meaning as 'despite' but is less commonly used. 'Due to' (choice D) is incorrect as it is used to show causation, which does not fit the context of the sentence.

Correct Answer: A

Rationale: The correct answer is 'was elected.' This choice is the most appropriate as it correctly indicates the action of being chosen through a voting process in the past. In this context, 'was elected' is the right verb form to show that John Kennedy became President in 1960 after winning an election. The other choices are incorrect: 'became' is a simple past verb form that doesn't convey the electoral process, 'was made' implies a passive action rather than an active election, and 'become' is not the correct past tense form needed in this sentence.
