Correct Answer: B

Rationale: In this sentence, 'results' is the direct object of the verb 'awaited,' functioning as a noun. Hence, option B, 'Noun,' is correct. The students were eagerly waiting for what? The results - which makes 'results' a noun in this context. Choices A, C, and D are incorrect. 'Results' is not describing a verb, an adjective, or an adverb in the sentence; it is the object of the students' anticipation, indicating a noun.

Correct Answer: C

Rationale: The sentence portrays intense emotions and agitation through actions like 'slammed' and the description 'booming with anger,' indicating a tone of agitation. The tone is not playful as it's intense and angry, not formal as it lacks restraint and is emotionally charged, and not melancholy as it conveys anger and not sadness. Therefore, 'Agitated' is the most suitable choice to describe the tone.

Correct Answer: B

Rationale: The correct answer is B because it uses 'literally' to emphasize the magnitude of work, not to exaggerate a simple action. In this sentence, 'literally' is used to convey the idea that the person climbed a significant amount of paperwork, highlighting the challenging and overwhelming nature of the task. Choices A, C, and D use 'literally' inappropriately by exaggerating or using the word in a non-literal sense. In choice A, 'died laughing' is a common expression and not meant to be taken literally. Choice C describes a figurative expression, not a literal one. Choice D involves the supernatural, which is not a literal occurrence.

Correct Answer: A

Rationale: Option A correctly uses the past perfect tense to show an action that was completed before another past action. In this sentence, 'the party had already begun' indicates that the party started before 'I arrived.' This structure is typical of the past perfect tense. Choice B uses the past perfect tense but does not demonstrate the sequence of actions in the past. Choice C uses the future perfect tense, indicating completion of an action by a future time. Choice D uses the past perfect continuous tense, not the simple past perfect tense required by the question.

Correct Answer: A

Rationale: Colons are used to introduce a list or explanation that follows an independent clause. In this case, option A correctly uses a colon to introduce a list of snacks after an independent clause. Choice B lacks an independent clause before the colon, making it incorrect. Choice C is incorrect as it should have an independent clause before the colon. Choice D incorrectly uses a colon as a comma would be more appropriate to introduce the list of items.
