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.

Beth was certain that tickets to the concert would sell quickly she ordered them online as soon the became available.
- A. quickly, she
- B. quickly, therefore
- C. quickly, so she
- D. quickly, then
Correct Answer & Rationale
Correct Answer: C
Option C, "quickly, so she," effectively connects Beth's belief about the tickets selling fast with her action of ordering them. The phrase "so she" indicates a cause-and-effect relationship, clarifying that her certainty motivated her decision. Option A, "quickly, she," lacks a clear connection between her belief and action, making the sentence feel incomplete. Option B, "quickly, therefore," is overly formal for this context and implies a logical conclusion rather than a direct action stemming from her belief. Option D, "quickly, then," suggests a sequence but does not imply causation, weakening the relationship between her certainty and her decision.

The following sentence would best fit immediately after which sentence in the second paragraph (sentences 3-6)? Meanwhile, the robots' eye and body movements mimic those of the human visitors they represent.
- A. Sentence 3
- B. Sentence 4
- C. Sentence 5
- D. Sentence 6
Correct Answer & Rationale
Correct Answer: C
The sentence about the robots’ eye and body movements aligns best with Sentence 5, which likely discusses how these movements enhance the interaction between robots and human visitors. This connection emphasizes the purpose of mimicking human behavior. Sentence 3 may introduce the robots but does not specifically relate to their movements. Sentence 4 might focus on a different aspect of the robots, such as their design or functionality, which doesn’t directly connect to the mimicry. Sentence 6 may conclude the paragraph, making it less suitable for introducing a detailed observation about movements. Thus, Sentence 5 provides the most relevant context for the new information.

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.

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.
