Which of the following choices would be the best beginning for an essay titled "Scientists Debate: Global Climate Change"?
- A. The Earth is heating up. The polar ice caps are melting, and whole species are going extinct while governments and scientists argue over rules and regulations.
- B. The argument seems to be about whether climate change is really happening and if so, who causes it. Some scientists argue that people are causing the change.
- C. If the Earth heats up, what will our new world look like? Scientists who have dedicated their lives to understanding climate change have projected a series of scenarios that could happen.
- D. While few people can understand all of the issues related to climate change, one thing is sure: scientists do not agree. There seem to be several different views on how to look at climate change data.
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.

Which of the following substitutions best captures the meaning of the word 'obsequious' in the sentence: 'The young apprentice was obsequious to his master, always eager to please'?
- A. showing deference
- B. poorly dressed
- C. reserved
- D. aggressive
Correct Answer: A
Rationale: The word 'obsequious' means excessively submissive or eager to please, often to the point of showing deference. In this context, 'showing deference' best captures the meaning, indicating respect or submission rather than being poorly dressed, reserved, or aggressive. 'Poorly dressed' (B) is unrelated to the meaning of obsequious. 'Reserved' (C) suggests a different behavior that is opposite to being obsequious. 'Aggressive' (D) is the opposite of obsequious and does not fit the context of the sentence.
What does the underlined word in the following sentence mean? 'The students' excitement about the beginning of summer vacation pervaded the whole classroom.'
- A. stood at attention
- B. spread throughout
- C. explained
- D. took note
Correct Answer: B
Rationale: The underlined word 'pervaded' in the sentence means 'spread throughout.' In this context, it conveys that the excitement of the students was felt and noticed everywhere in the classroom. Choice A, 'stood at attention,' does not align with the meaning of 'pervaded.' Choice C, 'explained,' and choice D, 'took note,' are also unrelated to the concept of the excitement spreading throughout the entire classroom.
In the words proactive, progress, and projecting, pro- is a(n) _______ and means _______.
- A. suffix; good/on top of/over
- B. prefix; before/forward/front
- C. affix; after/behind/in back of
- D. prefix; against/under/below
Correct Answer: B
Rationale: In the words proactive, progress, and projecting, 'pro-' is a prefix. A prefix is a morpheme added at the beginning of a word to modify its meaning. In this case, 'pro-' means before, forward, or front, indicating a sense of being proactive, making progress, or projecting ahead. Choice A is incorrect as 'pro-' is not a suffix. Choice C is incorrect as 'pro-' is not an affix that goes at the end or in the middle of a word. Choice D is incorrect as 'pro-' does not mean against, under, or below in the given context.
They were able to reach the deck fastest to get a seat on a lifeboat. Which of the following sentences is written correctly and provides a clear explanation?
- A. Because the majority of survivors came from first class, they were able to reach the deck fastest to get a seat on a lifeboat.
- B. Because of this, the majority of survivors came from first class, as they were able to reach the deck fastest to get a seat on a lifeboat.
- C. Because of this, the majority of survivors came from first class, they were able to reach the deck fastest to get a seat on a lifeboat.
- D. Because of this, the majority of survivors came from first class, as they were able to reach the deck fastest to get a seat on a lifeboat.
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.
Which of the following best explains the meaning of extraneous as it is used in the sentence? The report was filled with extraneous details that had nothing to do with the main findings of the study.
- A. sophisticated
- B. irrelevant
- C. diligent
- D. useful
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.
