Correct Answer: B

Rationale: The correct answer is B: 'To swallow for digestion.' Ingest means to take food, drink, or another substance into the body by swallowing it. Choice A, 'To chew,' is incorrect as chewing is the act of breaking down food with the teeth. Choice C, 'To spit out,' is incorrect as it is the opposite of ingesting, involving expelling something from the mouth. Choice D, 'To vomit,' is also incorrect as vomiting is forcibly expelling the contents of the stomach through the mouth, which is the opposite of ingesting.

Correct Answer: C

Rationale: "Pondering" is another word for contemplating because it means to think about something carefully or thoroughly. Both terms imply deep reflection or consideration of a subject or idea. Therefore, "pondering" best captures the meaning of contemplating among the given choices.

Correct Answer: B

Rationale: The correct answer is B: 'Able to be heard.' Audible refers to something that can be heard. Choice A, 'Impossible to hear,' is the opposite of the meaning of audible. Choice C, 'Visible,' is unrelated as it pertains to sight, not hearing. Choice D, 'Silent,' is also not correct as it refers to the absence of sound, which is different from something being able to be heard.

Correct Answer: B

Rationale: The correct answer is B: 'A deficiency or lack of something.' The term 'deficit' refers to a shortage or inadequacy of something. Choice A is incorrect because a surplus means an excess, which is the opposite of a deficit. Choice C is incorrect as an abundance signifies a large quantity or more than enough of something. Choice D is incorrect as a stable amount does not convey the concept of a deficit.

Correct Answer: B

Rationale: Manifestation means an indication or sign of a condition. It is not a treatment plan (choice C) or a type of diagnosis (choice D). While choice A is close, 'symptom' is more specific than 'indication' in this context, making choice B the most accurate.
