Passage
Just downstream from its confluence with the Missouri River, near the town of Alton, Illinois, the Mississippi River is nearly one mile across. In contrast, there are sections of the river near its source (Lake Itasca in Minnesota), where the Mississippi spans less than 20 feet from its right bank to its left.
The passage is mainly discussing the Mississippi River's
- A. depth
- B. length
- C. width
- D. location
Correct Answer & Rationale
Correct Answer: C
The passage primarily focuses on the Mississippi River's width, detailing its varying measurements at different points along its course. This emphasis on width highlights its significance in navigation and ecology. Option A, depth, is not the main topic; while depth may be mentioned, it does not receive the same level of attention. Option B, length, is also a lesser focus, as the passage does not delve into the river's overall distance. Option D, location, is addressed but serves more as context rather than the central theme. Thus, width emerges as the key aspect discussed in the passage.

Which is the best version of the underlined portion of sentence 3 (reproduced below)? High-tech teams around the world are working on projects designed to enhance people's telepresence "their sense of physically being in a location even when they are actually thousands of miles away.
- A. (as it is now)
- B. telepresence', their
- C. telepresence.' Their
- D. telepresence' their
Correct Answer & Rationale
Correct Answer: A
Option A maintains the original structure and punctuation, effectively conveying the intended meaning without introducing errors. The phrase "telepresence" is correctly followed by a quotation mark, and the sentence flows logically. Option B incorrectly uses a comma instead of a period after "telepresence," which disrupts the sentence's clarity and structure. Option C improperly replaces the comma with a period, creating a fragment because "Their sense..." would then be a standalone sentence without proper connection to the previous thought. Option D lacks the necessary punctuation to separate the two ideas, resulting in a confusing and grammatically incorrect construction.

What does the passage suggest about the light bulbs used in the first train signaling systems?
- A. They were very fragile.
- B. They were all the same color.
- C. They were only illuminated at night.
- D. They were also used to signal automobile drivers.
Correct Answer & Rationale
Correct Answer: B
The passage indicates that the light bulbs in the first train signaling systems were designed to emit a specific color to convey signals, suggesting uniformity in color for clarity and safety. Option A is incorrect as the passage does not mention the fragility of the bulbs. Option C is misleading; while the bulbs may have been primarily used at night, the passage does not explicitly state that they were only illuminated then. Option D is also incorrect; the passage focuses on train signaling without reference to their use for automobile drivers. Thus, the emphasis on color highlights the importance of consistent signaling in train operations.

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.

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.
