Correct Answer: C

Rationale: The correct answer is C: essential. In the context of the sentence, 'vital' means absolutely necessary or crucial for the victim's well-being. The word 'vital' emphasizes the critical importance of receiving immediate medical attention. It conveys the sense of urgency and importance in this situation. Incorrect choices: A: recommended - This choice suggests something that is advised but not necessarily crucial. It does not capture the urgent nature of the situation as conveyed by 'vital'. B: discouraged - This choice means the opposite of what 'vital' conveys. It implies that receiving medical attention is not desirable, which is not the case in the given sentence. D: sufficient - This choice implies that receiving medical attention is enough, but 'vital' goes beyond being just enough; it emphasizes the absolute necessity of immediate medical attention.

Correct Answer: D

Rationale: The correct answer is D because the verb "wore" agrees with the subject "I" in past tense. The other choices have verbs that do not match the subject or are not in the correct tense. A has "saw" which is the past tense of "see" but the subject is "I" not "you." B has "sang" which is the past tense of "sing" but again the subject is "I" not "the national anthem." C has "ran" which is the past tense of "run" but the subject is "I" not "Nibbles the Rabbit."

Correct Answer: D

Rationale: The correct answer is D: Back. The posterior part of the body refers to the rear or back side of the body. This is where structures like the spine, shoulder blades, and buttocks are located. Choice A, topmost, is incorrect as it refers to the superior aspect of the body. Choice B, lowermost, is incorrect as it refers to the inferior aspect of the body. Choice C, front, is incorrect as it refers to the anterior part of the body. Therefore, the correct answer is D because it accurately describes the location of the posterior part of the body.

Correct Answer: D

Rationale: The correct answer is D, "Quickly." In this sentence, "quickly" is an adverb modifying the verb "answering." Adverbs describe how an action is done, making it the appropriate choice to describe the manner in which answering should be done. Choices A, B, and C do not function as adverbs and do not properly modify the verb in the sentence. A simply functions as an adjective, B is incomplete, and C is not a correct comparative form. Therefore, "Quickly" is the correct choice for this sentence.

Correct Answer: D

Rationale: The correct answer is D: Themselves. In the sentence, 'Most children must learn for themselves the importance of good manners,' 'themselves' is the reflexive pronoun that correctly refers back to the subject 'children.' 'Themself' (A) and 'theirself' (B) are non-standard forms and are not grammatically correct. 'Theirselves' (C) is also incorrect as 'theirs' is a possessive pronoun, not a reflexive pronoun. Therefore, D is the only grammatically correct option that maintains subject-verb agreement and properly refers back to the subject in the sentence.
