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.

Why is the phrase "Amerigo the discoverer" (sentence 2) placed in quotation marks?
- A. To show that it is important
- B. To indicate that it is a direct quotation from a book
- C. To question whether Vespucci really discovered America
- D. To highlight the differences between the map and the book
Correct Answer & Rationale
Correct Answer: B
The phrase "Amerigo the discoverer" is placed in quotation marks to indicate that it is a direct quotation from a book, reflecting the specific wording used by the author. This helps readers recognize that the phrase is not the writer's own interpretation but a citation from another source. Option A is incorrect because quotation marks do not inherently signify importance. Option C misinterprets the purpose of the quotation marks, as they do not imply skepticism about Vespucci's discovery. Option D is also inaccurate, as the quotation marks focus on the phrase itself rather than any differences between a map and a book.

Our offices are located in an old building on the outskirts of campus that was formerly, a tavern.
- A. formerly
- B. formally
- C. formidably
- D. formality
Correct Answer & Rationale
Correct Answer: A
The word "formerly" accurately indicates that the building was previously a tavern, highlighting its past use. Option B, "formally," refers to official or ceremonial contexts, which does not fit the intended meaning. Option C, "formidably," suggests something impressive or intimidating, irrelevant in this context. Lastly, option D, "formality," denotes an official procedure or requirement, which is not applicable here. Thus, "formerly" is the only choice that correctly conveys the idea of a past state, making it the appropriate selection.

- A. The achievement of Richard Pearse
- B. The problems of early airplanes

- 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.
