Correct Answer: D

Rationale: The correct answer is D: Although. This conjunction is used to introduce a contrast or concession. In this sentence, it sets up a contrast between the fact that the emergency room was not busy and the head nurse still not allowing anyone to end their shift early. It emphasizes the unexpected or contradictory nature of the situation. A: Because indicates causation, which does not fit the context of contrasting information in the sentence. B: Provided that suggests a condition for something to happen, but it does not convey the intended contrast in the sentence. C: As if is used to describe a hypothetical situation or comparison, which is not the case in the sentence. In summary, D is the correct answer because it effectively conveys the contrasting information in the sentence, while the other choices do not fit the context.

Correct Answer: B

Rationale: The correct punctuation needed in the sentence is a comma (Choice B). The comma is used to separate the dependent clause "Because of a major accident on the freeway" from the independent clause "the emergency room was overcrowded." This creates a clear and correct sentence structure. A period (Choice A) would create two separate sentences, which is not necessary in this case. An exclamation point (Choice C) is inappropriate as the sentence is not expressing excitement or strong emotion. A semicolon (Choice D) is not suitable as the clauses are not closely related or part of a list.

Correct Answer: C

Rationale: The correct answer is C: "and new tires." This phrase is misplaced because it disrupts the parallel structure of the sentence. The sentence is about the car's characteristics (white roof) and ownership (belongs to our friends). The phrase "and new tires" should follow the white roof to maintain parallelism. Choices A, B, and D are all correctly placed within the sentence and contribute to its clarity and coherence.

Correct Answer: B

Rationale: The correct answer is B: "whose." In the sentence, "whose" is used incorrectly because it is a possessive pronoun indicating ownership, but in this context, it should be "where." The doctor's diploma is not owned by the doctor, but it is located on the partition. The word "where" should be used to show the location of the diploma. A: "That" is used correctly as a demonstrative pronoun referring to the doctor. C: "Hung" is used correctly as the past tense of "hang" to describe the action of placing the diploma on the partition. D: "Partition" is used correctly to refer to the divider where the diploma is hung.

Correct Answer: C

Rationale: The correct answer is C: boys'. In this sentence, the possessive form of "boys" should be "boys's" to indicate that the pranks belonged to the four boys. The incorrect use of the apostrophe after "boys" in choice C makes it the misspelled word. "Everyone" (choice A), "fraternity" (choice B), and "sophomoric" (choice D) are spelled correctly in the context of the sentence.
