Select the word that makes the following sentence grammatically correct. One of the students ___________ completed the course.
- A. have
- B. has
- C. are
- D. is
Correct Answer: B
Rationale: The correct word to use in this sentence is 'has' because 'One of the students' is singular, so it should be followed by a singular verb. The word 'has' is the correct singular form of the verb in this context. Choice A 'have' is plural, Choice C 'are' is also plural, and Choice D 'is' does not agree in number with the subject 'students'. Therefore, 'has' is the only correct choice here.

Which word is used incorrectly in the following sentence? The professor was once an intern in this hospital back in the 1980s.
- A. professor
- B. once
- C. intern
- D. hospital
Correct Answer: B
Rationale: In the given sentence, the word 'once' is used incorrectly. The original sentence implies that the professor was an intern in the hospital at a specific time in the past, not just once. The word 'formerly' would imply that the professor used to be an intern but is no longer. Therefore, 'once' is the incorrect word choice in this context. The other options ('professor,' 'intern,' 'hospital') are all used correctly in the sentence.
What punctuation is needed in the following sentence to make it correct? The days seem long, but the nights seem even longer.
- A. Period
- B. Comma
- C. Colon
- D. Apostrophe
Correct Answer: B
Rationale: The sentence needs a comma before the conjunction 'but' to correctly join the two independent clauses 'The days seem long' and 'the nights seem even longer.' This comma helps to create a clear separation between the contrasting ideas in the sentence. Choice A (Period) is incorrect because a period would create two separate sentences rather than connecting them. Choice C (Colon) is incorrect as colons are used to introduce lists, explanations, or quotations. Choice D (Apostrophe) is incorrect as it is not needed in this sentence.
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.
Which word is not spelled correctly in the context of the following sentence? Everyone in the fraternity found the four boys' pranks sophomoric.
- A. Everyone
- B. fraternity
- C. boys'
- D. sophomoric
Correct Answer: C
Rationale: The word 'boys'' should be spelled as 'boys' in this context. The correct possessive form of the plural noun 'boys' does not require an apostrophe before the final S, which indicates possession. In this sentence, the intent is to show that the pranks belong to the four boys collectively, so the correct possessive form is 'boys' without the additional apostrophe.
What word is best to substitute for the underlined words in the following sentence? The doctor and I went over the doctor's and my notes.
- A. his
- B. their
- C. our
- D. mine
Correct Answer: C
Rationale: The word 'our' is the best substitute for the underlined words 'the doctor's and my' in the sentence. Using 'our' indicates joint possession, making the sentence more concise and natural.
Choice A, 'his', is singular possessive and does not reflect the joint ownership implied by the sentence. Choice B, 'their', is plural possessive and does not align with the singular subjects 'the doctor and I'. Choice D, 'mine', is possessive for the first person singular pronoun and does not convey the shared ownership of the notes by both individuals.
