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.

According to the passage, why did the Peshtigo Fire receive little news coverage?
- A. The damage from the Peshtigo Fire was not as widespread as the damage from the Great Chicago Fire
- B. Because it was a forest fire, the Peshtigo Fire really did not affect too many people
- C. The Peshtigo Fire happened on the same day as a fire in a much bigger city
- D. Residents of Peshtigo never reported that the fire had occurred
Correct Answer & Rationale
Correct Answer: C
The Peshtigo Fire received little news coverage primarily because it coincided with the Great Chicago Fire, which captured the media's attention due to its larger urban impact. Option A is incorrect; while the damage was significant, the timing overshadowed it. Option B misrepresents the fire's impact, as it affected many residents despite being a forest fire. Option D is inaccurate; residents did report the fire, but their voices were drowned out by the focus on Chicago, highlighting the influence of media priorities rather than a lack of acknowledgment.

The retired government official spoke_______ about foreign policy and international trade.
- A. as knowing
- B. in knowledge
- C. knowledgeably
- D. knowledgeable
Correct Answer & Rationale
Correct Answer: C
Option C, "knowledgeably," is the appropriate choice as it is an adverb that describes how the retired government official spoke, indicating that he did so with knowledge and expertise. Option A, "as knowing," is grammatically incorrect in this context; it does not fit the structure of the sentence. Option B, "in knowledge," is awkward and does not function as an adverb, failing to appropriately modify the verb "spoke." Option D, "knowledgeable," is an adjective and does not correctly modify the verb, making it unsuitable for this sentence structure.

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.

The historic town library is just passed the intersection of Main Street and the more residential Frederick Street.
- A. passed
- B. pass
- C. past
- D. passing
Correct Answer & Rationale
Correct Answer: C
In this context, "past" is the appropriate choice as it refers to a location beyond a point—in this case, the intersection. - **A: passed** is the past tense of "pass," which does not fit the sentence's need for a preposition indicating location. - **B: pass** is the base form of the verb and does not convey the intended meaning of being beyond the intersection. - **D: passing** suggests an ongoing action, which is not suitable here as the sentence describes a static location relative to the intersection. Thus, "past" effectively communicates that the library is located beyond the intersection.
