1. Select the word that makes the following sentence grammatically correct. One out of four doctors ___________ to this plan.
- A. subscribe
- B. subscribes
- C. subscribing
- D. are subscribed
Correct answer: B
Rationale: In the sentence 'One out of four doctors,' the subject is 'One,' which is singular. Therefore, the verb that follows should also be singular. The correct verb form in this case is 'subscribes,' not 'subscribe' or any other form. This subject-verb agreement rule ensures that the sentence is grammatically correct. Choice A 'subscribe' is incorrect as it is in the plural form and does not agree with the singular subject. Choice C 'subscribing' is in the gerund form and does not function as the main verb of the sentence. Choice D 'are subscribed' is in the passive voice and does not match the active voice required in this sentence.
2. Which of the following sentences is grammatically correct: 'Walking home from class, ____'?
- A. the students watched the snow begin to fall
- B. the snow began falling on the students
- C. snow fell on the students
- D. the students watched the snow fall
Correct answer: A
Rationale: The correct answer is A: 'the students watched the snow begin to fall.' In this sentence, the structure is correct with the subject 'the students' followed by the verb 'watched' and the object 'the snow begin to fall' in a grammatically appropriate manner. Choices B, C, and D have issues with verb tense agreement and sentence structure, making them grammatically incorrect. Choice B changes the active voice to passive, choice C lacks a verb for the subject 'snow,' and choice D does not complete the action initiated in the introductory participial phrase.
3. Select the word that makes the following sentence grammatically correct: 'Tracey wore her hair in a French braid, ____ was the style at the time.'
- A. among
- B. it
- C. that
- D. which
Correct answer: D
Rationale: The correct answer is 'which' as it correctly introduces a defining clause describing the style of hair Tracey wore. 'Which' is used to provide additional information about the noun 'French braid' and helps specify the particular style among others. 'Among' (choice A) is incorrect as it is used to show a relation of one thing to many others. 'It' (choice B) is incorrect as it does not serve as a relative pronoun to introduce a clause. 'That' (choice C) is incorrect as it is not the most suitable relative pronoun to introduce a non-restrictive clause in this context.
4. Select the word or phrase that makes the following sentence grammatically correct: The wheelchair started _______ down the corridor without assistance.
- A. roll
- B. to roll
- C. rolled
- D. will roll
Correct answer: B
Rationale: The correct answer is 'to roll.' In this sentence, 'started' is followed by the infinitive form of the verb 'to roll.' The construction 'started to roll' indicates the beginning of the action of the wheelchair moving down the corridor. Choice A ('roll') is incorrect as it lacks the infinitive marker 'to' needed after 'started.' Choice C ('rolled') is incorrect as it is the past tense form of the verb, not suitable for the sentence's context. Choice D ('will roll') is incorrect as it indicates a future action, not the past action indicated by 'started.'
5. Select the word or phrase that makes this sentence grammatically correct. Before ________ this medicine, consume a modest meal.
- A. having taken
- B. taking
- C. took
- D. will take
Correct answer: B
Rationale: The correct form to use in this sentence is the present participle 'taking.' The sentence should read, 'Before taking this medicine, consume a modest meal.' It is important to use the present participle form when talking about an action that occurs before another action. Choice A 'having taken' is incorrect as it suggests a completed action before consuming a meal. Choice C 'took' is in the past tense, not suitable for indicating an action that should happen before another. Choice D 'will take' is in the future tense, which does not fit the context of the sentence.
