To vivify someone is to ___________.

Correct Answer: B

Rationale: To vivify someone means to give life or animation to them. It involves revitalizing or energizing someone, rather than belittling, alarming, or spoiling them. Therefore, the correct answer is "animate him" as it is the most suitable synonym for vivify in this context. Choices A, C, and D are incorrect as they do not align with the meaning of vivify.

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: A

Rationale: The word 'deleterious' means causing harm or damage. In this context, the sentence implies that the chemicals in plastic containers can be harmful to children's health. Therefore, the correct meaning of the underlined word is 'harmful,' making option A the most suitable choice. Option B 'Deleting' is incorrect because it refers to removing or erasing, which does not fit the context. Option C 'Delightful' is incorrect as it means causing great pleasure or delight, the opposite of the intended meaning. Option D 'Inoffensive' is incorrect as it means not causing any harm or annoyance, which is contrary to the negative impact described in the sentence.

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: 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.
