Rationale: In this context, the word 'predispose' means to create a tendency or susceptibility towards a particular condition or outcome. It implies an increased likelihood or vulnerability.

Rationale: Corrected Question: In this context, the word 'rationale' refers to the underlying reasoning or justification for the treatment being explained step-by-step by the doctor. It pertains to the logical basis or thought process behind the chosen course of action.

Rationale: Urea is the correct answer. It is the crystalline compound formed in the liver from the breakdown of proteins, a byproduct of protein metabolism. Urea is excreted by the kidneys in the form of urine, aiding in the elimination of nitrogenous waste from the body. Uracil (Choice A) is a nitrogenous base found in RNA, not a product of protein metabolism. Urine (Choice B) is the liquid waste excreted by the kidneys but not the crystalline compound resulting from protein metabolism. Ureter (Choice C) is a duct that carries urine from the kidneys to the bladder, not the compound produced from protein metabolism.

Correct Answer: C

Rationale: In this sentence, the word 'vent' means to allow the gases to escape or be emitted to the outside. 'Block' is incorrect because it means to obstruct or close off.

Correct Answer: D

Rationale: The correct meaning of 'disregard' in the sentence provided is 'to ignore.' When someone disregards something, they are choosing not to pay attention to it or consider it important.

Choice C, 'Care for,' is also the opposite of disregard, as caring for something implies giving it importance and attention.
