Correct Answer: B

Rationale: The term euphoric is best described as high-spirited. Euphoria is a feeling of intense happiness and excitement, so high-spirited accurately conveys the meaning of euphoric. Choices A, C, and D do not capture the essence of euphoria. 'Disease-ridden' has a negative connotation and is unrelated to euphoric. 'Pretentious' means attempting to impress by affecting greater importance, talent, culture, etc., than is actually possessed, which is not synonymous with euphoric. 'Understated' means presented or expressed in a subtle and effective way, which is not the meaning of euphoric.

Correct Answer: D

Rationale: The correct answer is D, Poison. A toxin is a harmful substance that can cause illness or death, and poison is a synonym commonly used to refer to such substances. Choices A, B, and C are incorrect because impurity refers to something being dirty or unclean, an element is a pure substance that cannot be broken down further, and a remedy is a solution or treatment for a problem, not a harmful substance like a toxin.

Correct Answer: B

Rationale: The word 'deferentially' means showing respect or submission to someone. Therefore, the closest synonym for 'deferentially' is 'respectfully' as it reflects the attitude and behavior of showing respect towards others. The other choices are incorrect: 'Imperfectly' means with flaws or errors, 'Competently' means having the necessary ability or skills, and 'Energetically' means with energy or enthusiasm, none of which capture the respectful connotation of 'deferentially.'

Correct Answer: B

Rationale: To censure something means to criticize or express strong disapproval of it. When something is censured, it is condemned or denounced for its actions or behavior. 'Inspect it' (Choice A) means to examine closely, 'admire it' (Choice C) means to regard with respect or warm approval, and 'overlook it' (Choice D) means to fail to notice or consider something. These choices do not align with the meaning of censure, making 'denounce it' (Choice B) the correct answer.

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.
