Which sentence uses 'etc.' grammatically correct?

Correct Answer: A

Rationale: The correct usage of 'etc.' should follow a comma when concluding a list. Option A correctly places 'etc.' at the end of a logical list with a comma before it, following grammatical rules. In option B, a comma should be placed after 'etc.' before introducing 'and other items.' Options C and D either misplace commas or incorrectly use 'etc.' within the list.

Correct Answer: D

Rationale: The correct answer is D: 'Soon to occur.' The word 'impending' is used to describe something that is about to happen or is soon to occur. In the context of the sentence provided, 'impending' operation indicates that the operation is about to take place. Choices A, B, and C are incorrect because 'impending' does not mean 'very serious,' 'required,' or 'elective.' Instead, it specifically refers to the timing of the operation as being imminent.

Correct Answer: C

Rationale: The correct answer is 'C: Preventive measure.' A precaution is a preventive action taken to avoid harm or danger. 'Rule' (A) and 'Habit' (D) do not capture the essence of being cautious to prevent something negative. 'Routine procedure' (B) is related to a regular way of doing things, but it does not specifically imply taking action to prevent harm.

Correct Answer: D

Rationale: The correct answer is 'D: Justification.' Justification means showing that an action is reasonable or right. In this context, it implies that there was no valid reason or excuse for the way she treated her boyfriend. Choices A, B, and C are incorrect. An 'alibi' is an excuse to explain one's whereabouts during a crime, not applicable here. 'Rational' means based on reason or logic, which does not fit the context of the sentence. 'Reasonable' means fair and sensible, but the sentence suggests a lack of valid explanation rather than fairness or sensibility.

Correct Answer: B

Rationale: The correct answer is 'Stimuli.' When forming the plural of 'stimulus,' the correct form is 'stimuli.' Choice A, 'Stimulus,' is the singular form, not the plural. Choice C, 'Stimulis,' is an incorrect spelling. Choice D, 'Stimula,' is also an incorrect form for the plural of 'stimulus.' Therefore, 'Stimuli' is the only correct plural form.

Correct Answer: C

Rationale: The correct answer is C: 'Sense of balance.' In the sentence provided, 'equilibrium' refers to a state of physical balance or stability. The client lost his balance when he woke up, indicating a loss of stability or equilibrium. Choices A, B, and D are incorrect because 'equilibrium' specifically refers to balance, not the ability to speak, sense of taste, or ability to swallow.

Correct Answer: D

Rationale: The correct answer is 'Ventral' because it specifically refers to the lower surface of a structure. 'Inferior' means below in position, 'Transverse' means situated across something, and 'Dorsal' refers to the upper side or back of a structure, making them incorrect in the context of the lower surface of a structure.

Correct Answer: C

Rationale: The correct meaning of 'ominous' is 'threatening' or indicating something bad is about to happen. A is incorrect because 'ominous' does not signify a good omen. B is incorrect as 'ominous' does not relate to deceit. D is incorrect as 'ominous' does not mean 'full of thought.' Therefore, the most suitable interpretation of 'ominous' in the given sentence is 'Threatening.'

Correct Answer: D

Rationale: The correct answer is D, 'Obstructed.' 'Occluded' means blocked or obstructed, indicating that the circulation to the foot was hindered. Choices A, B, and C are incorrect because 'occluded' does not mean normal, impaired, or inadequate but rather obstructed.
