Correct Answer: B

Rationale: In the context of the sentence, the word 'supplement' is used to mean adding something extra to enhance or complete the diet. Therefore, the meaning of the word is 'add to.' Choice A ('Replace') is incorrect because 'supplement' does not mean to substitute or exchange. Choice C ('Reflect') is incorrect because 'supplement' does not mean to mirror or show. Choice D ('Parallel') is incorrect because 'supplement' does not mean to correspond or be similar in a particular way.

Correct Answer: C

Rationale: Precipitous is best defined as being swift, meaning sudden, rapid, or happening quickly. It is often used to describe a steep and very steep drop or rise. The word does not refer to being damp, gentle, or dull. 'Damp' means slightly wet, 'gentle' means mild or moderate, and 'dull' means lacking interest or excitement.

Correct Answer: D

Rationale: The word 'elated' means to be ecstatically happy or joyful. Similarly, 'delighted' also means to be extremely pleased or filled with joy. Therefore, 'delighted' is another word that could be used to express the same meaning as 'elated.' Choices A, B, and C are incorrect. 'Edified' means to instruct or enlighten, 'confused' means to be unclear or bewildered, and 'flabbergasted' means to be astonished or amazed, which do not convey the same meaning as 'elated.'

Correct Answer: A

Rationale: In the sentence, the word 'suppress' is synonymous with the word 'subdue.' To suppress a cough means to reduce or restrain it, which aligns with the meaning of subdue. The other options are incorrect: 'Cure' implies completely eliminating the cough, 'Restore' means to bring back to a former condition, and 'Affect' is too general and does not capture the specific meaning of 'suppress' in this context.

Correct Answer: C

Rationale: In this context, the word 'quandary' refers to a state of uncertainty or confusion caused by being faced with a difficult decision or choice. This matches the meaning of option C. Choices A, B, and D are incorrect because 'quandary' does not relate to a place where rocks are mined (A), a journey of discovery (B), or a major attempt or trial (D), but rather to a state of uncertainty or confusion.
