Which sentence uses the passive voice correctly?

Correct Answer: A

Rationale: Option A correctly uses the passive voice by placing the emphasis on the object (letter) that received the action (was written) rather than the subject performing the action. The phrase 'by Mary' indicates the agent who performed the action, making it a clear example of the passive voice structure. Choices B, C, and D are all in the active voice, where the subject performs the action directly on the object. In the context of identifying the correct usage of the passive voice, option A stands out as the only suitable example.

Correct Answer: D

Rationale: 'Nonetheless' is the correct word to complete the sentence as it emphasizes the continuation of the concert despite the contrary circumstance. 'Nevertheless' and 'however' are synonyms and indicate contrast rather than continuity. 'Therefore' implies a conclusion or result, which is not fitting in this context.

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: C

Rationale: The correct answer is 'Idyllic' because it accurately captures the peaceful and picturesque nature of the setting. The image of a lone cabin nestled among towering pines with smoke curling from its chimney into the crisp mountain air evokes a sense of tranquility and beauty. 'Bland' (choice A) is incorrect as it suggests something dull or uninteresting, which does not align with the vivid imagery described. 'Urban' (choice B) is also incorrect as it refers to a city or town setting, which is the opposite of the isolated cabin in the mountains. 'Sterile' (choice D) is incorrect as it conveys a lack of warmth and character, which is not reflective of the cozy and inviting atmosphere portrayed in the description.

Correct Answer: B

Rationale: The word 'growing' in the sentence 'He felt a growing sense of unease' is functioning as an adjective. It describes the sense of unease, indicating a characteristic of the sense rather than an action (verb), a person, place, thing, or idea (noun), or modifying a verb, an adjective, or another adverb (adverb). Therefore, 'growing' is an adjective in this context.
