The most important things in my life are making money, traveling abroad, and _____.

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: 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'.

Correct Answer: A

Rationale: The correct answer is 'A: his injury.' In the context of completing a race, an injury would be a significant obstacle to overcome. While choices B, C, and D could also pose challenges, an injury is the most severe hindrance that would make completing a race particularly difficult. His condition, pain, or fatigue may affect performance, but they are not as directly impactful as an injury in this scenario.

Correct Answer: A

Rationale: The correct answer is A: 'The homework was completed by the student.' This sentence is in the passive voice because the subject (homework) is being acted upon by the student. In passive voice constructions, the subject receives the action rather than performing it. Choices B, C, and D are in active voice where the subject performs the action. In choice B, 'The student completed the homework,' the subject (student) is the one performing the action of completing the homework.
