Correct Answer: A

Rationale: 'Occluded' means blocked or obstructed, making 'Obstructed' the correct answer. In the context of a patient having an occluded artery, it implies that the artery is blocked. The other options, 'Open,' 'Broken,' and 'Cloudy,' do not accurately describe a blocked artery.

Correct Answer: B

Rationale: The word 'library' is incorrect in this context. It should be 'librarian' to be grammatically correct. The other choices ('an,' 'as,' 'during') are all grammatically correct and fit appropriately in the sentence.

Correct Answer: B

Rationale: The correct order of words to fit in the sentence structure is 'aide, aid, aid.' 'Aide' refers to a person who assists (nursing aide), while 'aid' refers to help or assistance (Band-aid and aid the nurse). Therefore, the sequence 'aide, aid, aid' correctly completes the sentence. Choices A, C, and D have the incorrect order of words that do not fit the sentence context.

Correct Answer: D

Rationale: The correct answer is D: 'forbid.' 'Proscribe' means to officially forbid or prohibit something. Choice A, 'anticipate,' is incorrect as it means to expect or predict something. Choice B, 'prevent,' is incorrect as it means to stop something from happening. Choice C, 'defeat,' is incorrect as it means to overcome or win against someone or something, which is not the meaning of 'proscribe.' Therefore, the most appropriate meaning for 'proscribe' among the given choices is to forbid.

Correct Answer: C

Rationale: The correct answer is C: 'cause it to happen.' 'Implement' means to put something into action or cause it to happen. Choices A, B, and D are incorrect because they do not reflect the meaning of 'implement.' Preventing something from occurring (Choice A), emphasizing the importance of something (Choice B), and following something from beginning to end (Choice D) are all different actions or concepts that do not align with the definition of 'implement.'
