Passage
The remarkable heliotropism of sunflowers makes these flowers worthy of their name. At sunrise, most sunflowers in the bud stage face east. Over the course of the day, as the Sun crosses the sky from east to west, the flowers turn accordingly. This motion is performed by a flexible segment of the stem called the pulvinus. As the bud stage ends, the stem hardens and sunflowers cease to be heliotropic
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.

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.

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.

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.

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.
