Correct Answer: A

Rationale: The correct answer is 'graduated.' In reported speech, the verb tense often shifts back, so 'graduated' (past tense) is the appropriate choice here. 'Completes' (present tense), 'finishes' (present tense), and 'finished' (past tense) are incorrect as they do not match the reported speech context where the verb tense typically shifts back. Therefore, 'graduated' is the most suitable choice to complete the sentence.

Correct Answer: A

Rationale: After robbing the bank, 'the thief fled' is the correct choice as it logically follows the action of robbing a bank. The singular pronoun 'he' in choice B is not appropriate as 'the thief' is singular. Choices C and D use 'they,' which is a plural pronoun and does not agree with 'the thief,' making them grammatically incorrect.

Correct Answer: B

Rationale: The correct answer is B: 'Confinement away from the general population.' Quarantine is the practice of isolating individuals who may have been exposed to a contagious disease but are not yet ill. This isolation helps prevent the potential spread of the disease. Choice A, 'Isolation,' is partially correct but does not capture the specific aspect of separation from the general population. Choice C, 'Treatment,' is incorrect as quarantine does not involve providing medical care but rather focusing on preventing transmission. Choice D, 'Exposure,' is also incorrect as quarantine is about separating potentially exposed individuals, not intentionally exposing them.

Correct Answer: D

Rationale: The sentence 'He runs fast' uses 'fast' correctly as an adverb. An adverb is used to describe a verb and in this case, 'fast' is describing how 'he runs.' Choices A, B, and C use 'fast' as an adjective, not an adverb. In choice A, 'fast' is describing the car, in choice B it is describing how the car drove, and in choice C it is describing the runner.

Correct Answer: C

Rationale: The word 'ephemeral' means lasting for a very short time. In this context, a vacationer feeling that their trip to Hawaii was too short implies that they found it to be brief or fleeting, making 'ephemeral' the most suitable choice among the options provided. Ponderous means slow and clumsy; salacious means obscene or lustful; erudite means showing great knowledge or learning. These words do not convey the idea of brevity or shortness, unlike 'ephemeral,' which perfectly fits the scenario described.
