Read the passage below and then choose the best answer to each question. Answer the questions on the basis of what is stated or impl the passage.
Passage
The first Tacoma Narrows Bridge, in Tacoma, Washington, opened to traffic on July 1, 1940. The bridge, which was intended to withstand high winds, collapsed four months later on November 7, 1940, due to a physical phenomenon known as aeroelastic flutter. Flutter is a self-feeding vibration that occurs when aerodynamic forces on an object couple with a structure's natural mode of vibration, producing rapid periodic motion. Thanks to the Tacoma collapse, engineers will never again overlook the problem of flutter: it has influenced the design of every great long-span bridge built since 1940.
The passage implies that the true cause of the bridge collapse was
- A. low-quality materials
- B. short-sighted design
- C. substandard craftsmanship
- D. unexpectedly high winds
Correct Answer & Rationale
Correct Answer: B
The passage suggests that the bridge collapse stemmed from a fundamental flaw in its design, indicating that the planning and engineering did not adequately account for structural integrity. Option A, low-quality materials, implies that the materials used were inferior, but the passage does not emphasize material quality as the primary issue. Option C, substandard craftsmanship, points to poor construction practices, yet the focus of the passage leans more toward design deficiencies rather than execution. Option D, unexpectedly high winds, suggests an external factor causing the collapse, but the passage attributes the failure to inherent design shortcomings rather than environmental conditions.

In 1952, Dwight Eisenhower was elected President of the United States, he won 55% of the vote.
- A. he won
- B. he had won
- C. with winning
- D. winning
Correct Answer & Rationale
Correct Answer: D
The phrase "winning" effectively conveys the action of Eisenhower's election in a succinct manner, emphasizing the achievement without the need for auxiliary verbs. Option A, "he won," is grammatically correct but less fluid in this context. It shifts focus to a completed action rather than the ongoing significance of his victory. Option B, "he had won," uses the past perfect tense, which implies a prior context that isn’t necessary here and complicates the sentence unnecessarily. Option C, "with winning," introduces an awkward prepositional phrase that detracts from the clarity and directness of the statement.

We can infer that the reason the glass tubes were bent was that
- A. the Paris Exposition display was considered unsatisfactory
- B. straight tubes are not as bright as bent ones
- C. it is difficult to form letters with straight tubes
- D. neon gas burns out quickly in straight tubes
Correct Answer & Rationale
Correct Answer: C
The bending of glass tubes is primarily linked to the ability to form letters and shapes, making option C the most logical choice. Bent tubes allow for the creation of recognizable letters, essential for signage. Option A suggests the display's quality influenced the design, but it lacks direct relevance to the functionality of the tubes. Option B implies that brightness is affected by the shape of the tubes, which is misleading; brightness is more about gas type and tube diameter than shape. Option D inaccurately claims that neon gas burns out quickly in straight tubes; gas longevity is not dependent on tube shape but rather on electrical conditions and gas quality.

In context, which of the following is the best way to revise and combine sentences 9 and 10 (reproduced below)? These robots are equipped with cameras and video screens. The robots allow the home-bound workers to attend meetings and interact more personally with their coworkers.
- A. These robots, while being equipped with cameras and video screens, allow the home-bound workers to attend meetings, interact more personally with their coworkers
- B. These robots are equipped with cameras and video screens, moreover, they allow the home-bound workers to attend meetings and interact more personally with their coworkers.
- C. Equipped with cameras and video screens, these robots allow the home-bound workers to attend meetings and interact more personally with their coworkers.
- D. In order to allow the workers to attend meetings and interact more personally with their coworkers, these robots are equipped with cameras and video screens
Correct Answer & Rationale
Correct Answer: C
Option C effectively combines the two sentences by starting with a participial phrase, "Equipped with cameras and video screens," which succinctly conveys essential information about the robots while maintaining clarity. This structure emphasizes the robots' capabilities and their purpose in a streamlined manner. Option A introduces unnecessary complexity with "while being," making the sentence less direct and harder to follow. Option B uses "moreover," which is inappropriate for connecting the two ideas and creates a run-on sentence that disrupts the flow. Option D alters the focus by suggesting that the robots are equipped solely for the purpose of allowing interaction, which misrepresents the original intent and adds unnecessary wording.

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.
