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.

Is it always better to be original than to imitate or use the ideas of others? Plan and write a multi-paragraph essay (300-600 words) in which you develop your point of view on the above question. Support your position with reasoning and examples taken from your reading, studies, experience, or observations.
Correct Answer & Rationale
Correct Answer:
Originality fosters creativity and innovation, allowing individuals to express unique perspectives and solutions. It encourages critical thinking and personal growth, as developing one's ideas often leads to deeper understanding and mastery of a subject. Conversely, imitation can stifle creativity and limit personal expression. While learning from others can be beneficial, relying solely on their ideas may hinder the development of one's voice and perspective. Furthermore, excessive imitation can lead to plagiarism and a lack of authenticity, which are detrimental in academic and professional settings. In summary, while there is value in learning from others, prioritizing originality cultivates a richer, more diverse intellectual landscape.

According to scientists, the seven separate continents of the world, in the far distant past, one vast land mass.
- A. the world, in the far distant past
- B. the world, being in the far distant past
- C. the world were, in the far distant past
- D. the world was, in the far distant past
Correct Answer & Rationale
Correct Answer: D
Option D accurately uses the verb "was," which agrees with the singular subject "the world." This structure clearly conveys that, historically, the continents formed one vast land mass. Option A lacks a verb, making it an incomplete thought. Option B incorrectly uses "being," which is not suitable in this context and disrupts the sentence's clarity. Option C uses "were," which does not agree with the singular subject and creates confusion about the subject-verb relationship. Thus, D is the only option that maintains grammatical correctness and clarity.

The author of Passage 1 would probably say that the claims in the last sentence of Passage 2 ("Someday notice") are
- A. disappointing and inaccurate
- B. stimulating and insightful
- C. optimistic but vague
- D. alarming but truthful
Correct Answer & Rationale
Correct Answer: A
Passage 1 likely emphasizes a critical perspective on claims that lack substantiation, making option A—disappointing and inaccurate—the most fitting choice. This aligns with a viewpoint that values factual accuracy and clarity. Option B, stimulating and insightful, misrepresents the author's likely skepticism towards unsupported claims. C, optimistic but vague, suggests a positive outlook that contrasts with the author's critical stance. D, alarming but truthful, implies an acceptance of the claims' validity, which contradicts the author's probable disapproval of inaccuracies. Thus, A best captures the author's likely viewpoint.

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.
