Rationale: The correct answer is B: Praiseworthy. An exemplary record indicates outstanding performance. Therefore, the doctor's work is deserving of praise. Choice A is incorrect as it suggests mediocrity. Choice C is incorrect as it implies a negative performance. Choice D is incorrect as it suggests lack of clarity, which is not related to the doctor's performance.

Correct Answer: C

Rationale: Rationale: 1. Contemplating means deep thinking or reflecting. 2. Pondering also means to reflect or consider deeply. 3. Impasse means a deadlock or stalemate, not related to contemplating. 4. Impartial means unbiased, not directly related to contemplating. 5. Emending means to make corrections, not synonymous with contemplating. Summary: - A (Impasse) and D (Emending) are incorrect as they do not relate to contemplating. - B (Impartial) is incorrect as it does not represent the act of deep thinking. - C (Pondering) is correct as it directly aligns with the meaning of contemplating, involving thoughtful consideration.

Correct Answer: B

Rationale: The correct answer is B: Significantly important and dangerous. "Ominous" means giving the impression that something bad or unpleasant is going to happen. The word carries a sense of foreboding or threat. Choice A, "insignificant," is incorrect because ominous implies significance. Choice C, "trivial," is incorrect as it suggests unimportance, which is opposite to the meaning of ominous. Choice D, "harmless," is incorrect because ominous implies a potential for harm or danger. Therefore, the correct answer is B as it best captures the meaning of ominous in the context of something being important and dangerous.

Correct Answer: A

Rationale: The correct answer is A: dilate. Eye drops that dilate the pupils are commonly used to prepare for eye exams as they cause the pupils to expand or open up. This allows more light to enter the eye and provides a better view of the back of the eye. Constrict (choice B) means to narrow or make smaller, which is the opposite effect needed for an eye exam. Enlarge (choice C) is incorrect as it means to make something larger, which is not the intended effect. Decrease (choice D) is also incorrect as it means to make something smaller, which is opposite of what is required for an eye exam.

Correct Answer: B

Rationale: The correct answer is B: A deficiency or lack of something. 'Deficit' refers to a shortage or insufficiency of a particular quantity or quality. It is the opposite of an excess (choice A), abundance (choice C), or a stable amount (choice D). The term 'deficit' specifically implies a lack or inadequacy in comparison to what is required or expected.
