Correct Answer: A

Rationale: The underlined word "margin" in the sentence refers to the edge or border of something. In this context, it specifically refers to the edge of the gingiva or gum tissue around the teeth. Therefore, the correct meaning is "A: Edge." Explanation of other choices: B: Grease - This does not relate to the context of applying gel on the gingival margin. C: Incisor - This refers to a type of tooth, not the correct meaning of "margin." D: Cavity - This refers to a hole or hollow space, not the correct meaning of "margin." In summary, the correct answer "A: Edge" is the most appropriate choice based on the context of the sentence, while the other options do not fit the meaning of the word "margin" in this context.

Correct Answer: D

Rationale: The correct answer is D: Intense. In the sentence, the word "acute" is used to describe the pain of childbirth, indicating that the pain is sharp and severe, which aligns with the definition of intense. The other choices can be ruled out based on their meanings. A: Escalating implies increasing gradually, B: Emergent means coming into view or becoming known, and C: Eased means to make something less severe or intense. Therefore, D: Intense is the most appropriate choice as it best captures the meaning of "acute" in the context of the sentence.

B: Dimness - Dimness refers to low light levels and has no connection to heavy rainfall. D: Chasm - A chasm is a deep fissure or gorge in the earth, not related to heavy rainfall.

Deep tendon reflex (A) refers to a neurological assessment, descending thorax (B) is not a recognized medical term, and dextrose in water (D) is a solution used for intravenous administration. Therefore, C is the correct choice based on the context of patient care and medical terminology.

B: Selfless - This word has a positive connotation, which does not fit the context of the sentence. C: Tolerant - This word means showing acceptance or openness, which contrasts with the aggressive behavior implied by "bellicose."
