Read the passage below and then choose the best answer to each question. Answer the questions on the basis of what is stated or implied in the passage.
Passage
Today's ubiquitous red-yellow-green electric traffic light, familiar to drivers worldwide, had its origins in train signals from the 1800s. These early signals all used red to signify "stop," but the choice and arrangement of the other two colors would surprise today's drivers: green was the color for "caution," and white was the color for "go." However, white proved to be a poor choice, because the red and green lights train engineers saw were produced by red and green filters covering white light bulbs (the "go" light had a clear filter). If a filter was broken or missing, the signal would appear as white and engineers might mistake "stop" or "caution" for "go," especially at night.
What does the passage suggest about the light bulbs used in the first train signaling systems?
- A. They were very fragile.
- B. They were all the same color.
- C. They were only illuminated at night.
- D. They were also used to signal automobile drivers.
Correct Answer & Rationale
Correct Answer: B
The passage indicates that the light bulbs in the first train signaling systems were designed to emit a specific color to convey signals, suggesting uniformity in color for clarity and safety. Option A is incorrect as the passage does not mention the fragility of the bulbs. Option C is misleading; while the bulbs may have been primarily used at night, the passage does not explicitly state that they were only illuminated then. Option D is also incorrect; the passage focuses on train signaling without reference to their use for automobile drivers. Thus, the emphasis on color highlights the importance of consistent signaling in train operations.

Is it always better to be original than to imitate or use the ideas of others? Plan and write a multi-paragraph essay (300-600 words) in which you develop your point of view on the above question. Support your position with reasoning and examples taken from your reading, studies, experience, or observations.
Correct Answer & Rationale
Correct Answer:
Originality fosters creativity and innovation, allowing individuals to express unique perspectives and solutions. It encourages critical thinking and personal growth, as developing one's ideas often leads to deeper understanding and mastery of a subject. Conversely, imitation can stifle creativity and limit personal expression. While learning from others can be beneficial, relying solely on their ideas may hinder the development of one's voice and perspective. Furthermore, excessive imitation can lead to plagiarism and a lack of authenticity, which are detrimental in academic and professional settings. In summary, while there is value in learning from others, prioritizing originality cultivates a richer, more diverse intellectual landscape.

In sentence 8 (reproduced below), which of the following best replaces 'they'? Rather than commuting long distances, they can use their home computers to maneuver simple wheeled robots around the head office
- A. high-tech engineers
- B. remote workers
- C. sophisticated robots
- D. employers
Correct Answer & Rationale
Correct Answer: B
Option B, "remote workers," accurately identifies the subject who would benefit from using home computers to control robots instead of commuting. This term directly relates to individuals who work from home, aligning with the context of the sentence. Option A, "high-tech engineers," is too specific and does not encompass all individuals who might work remotely. Option C, "sophisticated robots," incorrectly refers to machines rather than people, making it irrelevant in this context. Option D, "employers," shifts the focus from the workers to those who manage them, which does not fit the intended meaning of the sentence.

The author of Passage 1 would probably say that the claims in the last sentence of Passage 2 ("Someday... notice") are
- A. disappointing and inaccurate
- B. stimulating and insightful
- C. optimistic but vague
- D. alarming but truthful
Correct Answer & Rationale
Correct Answer: A
The claims in the last sentence of Passage 2 are likely viewed as disappointing and inaccurate because they may contradict the author's perspective in Passage 1, which emphasizes realism over idealism. Option B, "stimulating and insightful," misinterprets the author's critical stance; the claims are not presented as thought-provoking. Option C, "optimistic but vague," overlooks the author's likely skepticism towards vague claims that lack concrete support. Option D, "alarming but truthful," fails to capture the author's likely rejection of the claims as factual, indicating a more critical viewpoint.

The passage indicates that John Neville was
- A. the creator of the whiskey tax
- B. working for the government
- C. pardoned by the government
- D. a friend of George Washington's
Correct Answer & Rationale
Correct Answer: B
John Neville was indeed working for the government, specifically as a tax collector during the Whiskey Rebellion, which highlights his role in enforcing federal tax laws. Option A is incorrect; he did not create the whiskey tax but was involved in its implementation. Option C is misleading, as there is no indication in the passage that he was pardoned by the government. Option D is also wrong; while Neville may have had connections, the passage does not confirm him as a friend of George Washington. Thus, his official capacity as a government worker is the most accurate representation of his role.
