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.

Correct Answer: B

Rationale: The correct preposition to use in this sentence to indicate the position of the fountain in relation to the driveway and the main entrance is 'between.' 'Between' conveys that the fountain is positioned centrally or in the middle of the driveway and the main entrance, making it the most suitable phrase to complete the sentence correctly. The other options do not accurately describe the fountain's position between two distinct locations, making them grammatically incorrect choices for this sentence.

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.

Correct Answer: B

Rationale: The correct sentence should be: 'Because of a major accident on the freeway, the emergency room was overcrowded.' A comma is needed after 'freeway' to separate the introductory dependent clause from the independent clause that follows. Choice A (Period) is incorrect as it would create two separate sentences. Choice C (Exclamation point) is incorrect as there is no exclamation in the sentence. Choice D (Semicolon) is incorrect as it is used to separate closely related independent clauses.

Correct Answer: D

Rationale: The word 'his' is the possessive form of the pronoun 'Mr. Menotti,' indicating that the belongings belong to him. Using 'her,' 'him,' or 'he' would not be grammatically correct in this context as they do not reflect the possession by Mr. Menotti. 'Her' would imply the belongings belong to his wife, 'him' is an objective pronoun, and 'he' is a subject pronoun, neither of which correctly shows possession.
