Correct Answer: C

Rationale: The correct answer is C: 'Read thoroughly.' The word 'perused' means to read or examine carefully or in detail. It does not imply passing judgment, engaging in, or taking notes. Choices A, B, and D are incorrect because 'perused' specifically refers to reading thoroughly, not making judgments, participating in, or taking notes.

Correct Answer: C

Rationale: In this context, the word 'undergo' means to experience or go through a process. When someone undergoes something, it implies they are subjected to it or experiencing it. Therefore, in the sentence provided, 'experience' is the correct meaning. Choices A, B, and D are incorrect as they do not align with the idea of going through a process or experiencing something.

Correct Answer: D

Rationale: If illegal operators are posing as licensed pharmacists, they are pretending to be licensed pharmacists when they are not. This deceptive behavior is misleading and potentially dangerous for consumers seeking legitimate medical advice and products. Choice A, modeling, implies imitating behavior or appearance, which is not the case here. Choice B, inquiring, suggests seeking information or asking questions, which is not the correct behavior in this context. Choice C, positioning, refers to arranging or placing things in a particular way, which is not relevant to the situation described in the question.

Correct Answer: A

Rationale: In this context, the word 'margin' refers to the border or edge of the gums around the teeth. The gel is supposed to be applied on the gingival margin, which means on the edge or border of the gums near the selected teeth. Choice B, 'Grease,' is incorrect as it does not relate to the application of gel on the gums. Choice C, 'Incisor,' refers to a type of tooth and is unrelated to the context of applying gel on the gingival margin. Choice D, 'Cavity,' is also unrelated as it refers to a decayed area in a tooth and not the border of the gums.

Correct Answer: D

Rationale: The word "acute" in this sentence means intense. Acute pain is sharp or severe, which accurately describes the level of pain experienced during childbirth. Choice A, "Escalating," suggests increasing pain over time, which is not necessarily implied by the word "acute." Choice B, "Emergent," means arising or coming into view, which does not capture the intensity of the pain. Choice C, "Eased," means to make less severe, which is the opposite of what is described in the sentence.
