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.

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.

The word "perceive" in sentence 3 of the passage most nearly means
- A. feel
- B. generate
- C. predict
- D. sense
Correct Answer & Rationale
Correct Answer: D
The word "perceive" in this context closely aligns with "sense," as it refers to the ability to become aware of something through one’s senses or intuition. Option A, "feel," suggests a more emotional or physical response, which does not fully capture the broader cognitive aspect of perception. Option B, "generate," implies creating something, which deviates from the idea of recognizing or understanding. Option C, "predict," relates to forecasting future events, rather than simply recognizing or interpreting current stimuli. Thus, "sense" best encapsulates the meaning of "perceive" in this instance.

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.
