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.

The author includes and defines the words "gargouille" and "gurgulio" primarily to
- A. describe the physical appearance of gargoyles
- B. connect the name and function of gargoyles
- C. establish the geographical origin of gargoyles
- D. suggest the artistic and cultural value of gargoyles
Correct Answer & Rationale
Correct Answer: B
The inclusion and definition of "gargouille" and "gurgulio" serve to connect the names of these figures with their function as water spouts, emphasizing their practical purpose in architecture. Option A is incorrect as the definitions focus more on the names rather than physical descriptions. Option C is not supported, as the terms do not specifically indicate geographical origins but rather their meanings. Option D suggests a focus on artistic value, which is not the primary intent of defining these terms; the emphasis is on their functional role rather than their cultural significance.

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.

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.

Our math teacher claimed that calculus, despite its complexities, were as easy as any other subject.
- A. were as
- B. was as
- C. is to be
- D. to be
Correct Answer & Rationale
Correct Answer: B
In this context, the subject "calculus" is singular, so it requires a singular verb form. "Was as" correctly matches the singular subject, indicating that calculus is being compared to other subjects in the past. Option A, "were as," incorrectly uses the plural verb "were," which does not agree with the singular noun "calculus." Option C, "is to be," implies a future action or state, which does not fit the intended meaning of comparing past experiences. Option D, "to be," lacks a verb and does not form a complete thought, making it grammatically incorrect.
