Long before his death, Pablo Picasso became one of the most important artists in history.

Correct Answer: B

Rationale: The correct answer is 'Became.' In this sentence, we need the simple past tense 'became' to describe the action that occurred in the past. 'Become' (choice A) is incorrect as it is the base form of the verb and doesn't fit the sentence structure. 'Been' (choice C) is incorrect as it is the past participle and doesn't match the sentence context. 'Had become' (choice D) is unnecessary as the sentence doesn't require the past perfect tense.

Correct Answer: A

Rationale: The correct answer is 'living well.' The sentence lists actions using '-ing' forms (making, traveling, and living), so 'living well' maintains parallel structure. Choice B ('to live well') breaks this structure by introducing an infinitive form. Choice C ('to be happy') introduces a new action not in parallel with the others. Choice D ('enjoying life') changes the structure and focuses on a different action not consistent with the previous activities listed.

Correct Answer: A

Rationale: The correct answer is 'dilate.' Eye drops are used to dilate the pupils, meaning to widen or enlarge them, which is necessary for an eye exam to allow more light to enter the eye. 'Constrict' (choice B) means to make smaller, which is the opposite effect needed for an eye exam. 'Enlarge' (choice C) is similar in meaning to dilate but is not the correct term used in this context. 'Decrease' (choice D) means to make less or reduce, which is also the opposite of what is required for an eye exam.

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: B

Rationale: The sentence 'She was present at the meeting' uses 'present' as an adjective. In this context, 'present' describes her state of being at the meeting. The other choices use 'present' as a verb (to give), a noun (a gift), and a verb (to show), making them incorrect in the context of looking for the adjective use of 'present'.
