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.

The term "heliotropic" (sentence 5) most probably means
- A. having a flexible pulvinus
- B. flowering in the bud stage
- C. having brightly-colored flowers
- D. turning toward the Sun
Correct Answer & Rationale
Correct Answer: D
"Heliotropic" refers to the phenomenon where plants or flowers turn towards the Sun to maximize light exposure, which is essential for photosynthesis. This behavior is crucial for their growth and survival. Option A, "having a flexible pulvinus," describes a specific structural feature of some plants but does not capture the essence of heliotropism. Option B, "flowering in the bud stage," pertains to a developmental phase unrelated to sunlight orientation. Option C, "having brightly-colored flowers," focuses on visual attributes rather than movement towards light. Thus, only option D accurately reflects the meaning of heliotropic.

What is the passage primarily discussing?
- A. The achievement of Richard Pearse
- B. The problems of early airplanes
- C. The first flight in the United States
- D. The history of long-distance flight
Correct Answer & Rationale
Correct Answer: A
The passage primarily discusses the achievement of Richard Pearse, highlighting his significant contributions to aviation. His pioneering efforts are central to the narrative, showcasing his innovations and milestones. Option B focuses on the problems of early airplanes, which, while relevant, does not capture the primary focus on Pearse's accomplishments. Option C mentions the first flight in the United States, a separate historical event that is not the main topic of the passage. Option D addresses the broader history of long-distance flight, which encompasses many figures and events, but does not specifically center on Pearse's individual achievements.

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.

What does the passage imply about Jimmy Page?
- A. Page played the theremin in an unorthodox way
- B. Page wrote the song "Whole Lotta Love" for the theremin
- C. Page was primarily a guitarist, not a thereminist
- D. Page was a master of many instruments, including the theremin
Correct Answer & Rationale
Correct Answer: C
The passage suggests that Jimmy Page is primarily recognized as a guitarist, emphasizing his main role in music. Option A incorrectly implies that Page played the theremin in a notable manner, which is not supported by the text. Option B wrongly claims he wrote "Whole Lotta Love" specifically for the theremin, while the song is more associated with his guitar work. Option D suggests he was a master of multiple instruments, including the theremin, but the focus on his guitar skills indicates that this is not the primary takeaway. Thus, the passage highlights Page's identity as a guitarist.
