Which of the following substitutions best captures the meaning of the underlined words in the sentence below? "She was perturbed by the loud noise coming from the construction site."

Correct Answer: A

Rationale: The word 'perturbed' in the sentence conveys a sense of being troubled, disturbed, or bothered by something. Therefore, the most suitable substitution is 'bothered by.' Option A correctly captures the feeling of being unsettled due to the loud noise. Choice B, 'excited about,' does not align with the negative connotation of 'perturbed.' Choice C, 'occupied exclusively with,' introduces a different concept unrelated to feeling troubled by the noise. Choice D, 'confused by,' does not accurately reflect the feeling of being troubled or bothered by the situation described in the sentence. Thus, 'bothered by' is the most appropriate substitution in this context.

Correct Answer: D

Rationale: The prepositional phrases in the sentence are 'as a class' and 'into small groups,' making choices (a) and (c) correct. The phrase 'when we arrive' is not a prepositional phrase but rather a subordinate clause indicating a time. Prepositional phrases typically begin with a preposition (as, into) and end with a noun, pronoun, gerund, or clause. Therefore, the correct answer is option D, as it correctly identifies the prepositional phrases in the sentence.

Correct Answer: C

Rationale: Choice C would be the best beginning for an essay on 'Scientists Debate: Global Climate Change' because it sets the stage for discussion by introducing the potential consequences of Earth heating up and inviting readers to consider the implications. It also highlights the expertise of scientists who have dedicated their lives to understanding climate change, positioning them as credible sources for further discussion on the topic. The other choices either focus on the existing debate without providing a broader context (A and D) or present a narrow view on whether climate change is real and human-caused (B) without delving into the broader implications and discussions within the scientific community.

Correct Answer: A

Rationale: Option A most effectively revises the introduction by clearly stating that English novelist Mary Shelley had an immeasurable impact on literature and popular culture through her conception of Dr. Frankenstein and the hideous monster he created. It maintains the original idea while improving clarity and coherence. Option B introduces confusion by implying that Dr. Frankenstein created the hideous monster when it was actually Mary Shelley who conceived both characters. Option C lacks the necessary conjunctions to make the sentence flow smoothly. Option D unnecessarily specifies the country of origin for Mary Shelley and does not maintain the focus on her impact on literature and popular culture.

Correct Answer: D

Rationale: The purpose of the parentheses in the sentence is to set off useful information that does not fit directly into the flow of the sentence. Parentheses are commonly used to provide additional details, explanations, or examples that are helpful but not essential to the main point of the sentence. In this case, the information about the Austro-Hungarian Empire is presented in parentheses to offer context but is not crucial to the main idea being communicated. Choices A, B, and C are incorrect as they do not accurately describe the function of parentheses in this context.

Correct Answer: B

Rationale: The correct answer is 'forgiven' as it is a past participle. A past participle is used to indicate an action that has already occurred in the past. In this sentence, 'forgiven' describes the state of Logan having forgiven Marianne. Choice A, 'telling', is a present participle, not a past participle, which is used for ongoing or continuous actions. Choice C, 'and', is a conjunction that connects phrases or words. Choice D, 'treat', is a verb in its base form, not a past participle.

Correct Answer: D

Rationale: Option D is the clearest revision as it expresses the student's concern directly through dialogue. The use of quotation marks provides clarity, and the student's worry about failing is stated clearly. The other options either lack clarity or contain grammatical issues. Option A introduces an unnecessary condition with 'unless' which changes the original meaning. Option B introduces a third-person perspective that is not present in the original sentence. Option C is awkwardly constructed and does not convey the student's concern effectively.

Correct Answer: B

Rationale: Option B provides a clear and grammatically correct explanation for why the majority of survivors came from first class - they were able to reach the deck fastest to get a seat on a lifeboat. The phrase 'Because of this' properly introduces the reason that follows. In Option A, a comma after 'Because' is unnecessary and disrupts the flow of the sentence. In Option C, 'Because this' is incomplete and lacks proper connection to the subsequent clause. Option D, similar to Option C, lacks clarity due to the absence of a full linking phrase. Therefore, Option B is the best choice as it conveys the explanation effectively and without grammatical errors.

Correct Answer: B

Rationale: The word 'extraneous' means something that is irrelevant or unnecessary to the main topic at hand. In the given sentence, 'extraneous' is used to describe details that are not related to the main findings of the study, indicating that they are unnecessary and irrelevant. Therefore, 'irrelevant' is the correct explanation. Choices 'sophisticated,' 'diligent,' and 'useful' do not convey the concept of being unnecessary or unrelated, making them incorrect in the context of the sentence.
