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: B

Rationale: Exposure means coming into contact with something, which aligns with option B. Exposure involves encountering or being subjected to a particular factor or substance. Option A is incorrect as protection is the opposite of exposure. Option C is incorrect as absorption is a specific process following exposure. Option D is incorrect as isolation implies being separated from exposure.

Correct Answer: B

Rationale: The correct answer is B: Produced within the body. Endogenous refers to something that originates or is produced internally by the body. In this context, endogenous substances are naturally produced by the body's cells or organs. Choices A, C, and D are incorrect because endogenous specifically refers to internal production and is not related to being produced outside the body, taken from an external source, or linked to environmental factors. Therefore, the correct choice is B as it accurately reflects the definition of endogenous.

Correct Answer: B

Rationale: The correct answer is B: Wide open. "Gaping" typically refers to something being wide open or having a large opening. This can be inferred from the word itself, as "gaping" implies a significant space or opening. Choices A, C, and D are incorrect because they do not align with the typical meaning of "gaping." A (Partially closed) suggests the opposite of what "gaping" means, C (Narrow) implies a small opening rather than a wide one, and D (Sealed) indicates something being completely closed rather than open. By process of elimination and understanding the definition of "gaping," the correct answer is B.

Correct Answer: B

Rationale: The correct answer is B: The distance across the center of an object. The diameter of a circle is a straight line passing through the center, connecting two points on the circumference. It is twice the length of the radius. Choice A is incorrect as width typically refers to the measurement from side to side, not necessarily through the center. Choice C is incorrect as height is a vertical measurement, not related to the diameter of an object. Choice D is incorrect as the radius is half of the diameter, not the same.
