Correct Answer: B

Rationale: The correct answer is B: Abrupt. In the sentence, 'precipitous' is describing a change that happened suddenly or unexpectedly. This aligns with the definition of 'abrupt,' meaning sudden or unexpected. The other choices, A: Difficult, C: Gentle, and D: Unanticipated, do not accurately capture the meaning of 'precipitous' in the context of the sentence. 'Difficult' refers to challenges, 'gentle' suggests something calm or mild, and 'unanticipated' means not expected, none of which fully match the context of a sudden change described as 'precipitous.'

Correct Answer: A

Rationale: The correct answer is A: Ain't. "Ain't" is a colloquial and informal term that is considered incorrect in formal writing. In this context, a more appropriate word would be "isn't." The word "during" is correctly used to indicate a specific time period. "Sure" is used correctly as an adverb to express certainty. "Playoff" is also used correctly to refer to a sports competition. Overall, "ain't" is the only word that is not used correctly in standard English.

Correct Answer: A

Rationale: The correct answer is A because 'fast' is used as an adverb to describe how the cars moved. Adverbs modify verbs, adjectives, or other adverbs. In this sentence, 'fast' modifies the verb 'moved'. Choice B uses 'fast' as an adjective to describe the clock, not an adverb. Choice C uses 'fast' as an adjective to describe the pitch, not an adverb. Choice D uses 'fast' as an adjective to describe the cars, not an adverb. Therefore, the sentence in choice A is the only one where 'fast' is correctly used as an adverb.

Correct Answer: A

Rationale: The correct answer is A: Obstructed. In the context of the sentence, 'occluded' means blocked or obstructed. An occluded artery refers to a blocked artery, typically due to a buildup of plaque or a blood clot. This impedes blood flow and can lead to serious health issues. The other choices, B: Open, C: Broken, and D: Cloudy, do not accurately capture the meaning of 'occluded' in the given context. 'Open' implies the opposite of occluded, 'Broken' is unrelated to artery blockage, and 'Cloudy' does not convey the concept of blockage or obstruction.

Correct Answer: B

Rationale: The correct answer is B: Cervical opening. In the context of labor, dilation refers to the opening of the cervix to allow the baby to pass through during childbirth. Blood pressure (A), birth process (C), and exhumation (D) are not related to the specific medical term dilation in this context.
