(1) The dream of being instantly transported from one point on the globe to another has thus far been confined to the realm of science fiction. (2) However, thanks to technological advances, researchers are low closer than ever to making that dream- or at least a version of it- a reality
(3) 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. (4) Users of this developing technology can "visit" faraway destinations embodied in sophisticated robots. (5) The visitors wear goggles and suits with sensors that allow them to see and feel in real time what their robot avatars are experiencing. (6) Microphones, speakers, and headphones allow two-way communication with the people at the other end, providing the visitors with a true sense of physically being there
(7) Cruder forms of telepresence robots are already being used in some American offices, (8) Rather than commuting long distances, they can use their home computers to maneuver simple wheeled robots around the head office. (9) These robots are equipped with cameras and video screens. (10) The robots allow the home-bound workers to attend meetings and interact more personally with their coworkers
(11) A host of ethical issues must still be overcome before these technologies become widespread including concerns over whether telepresence robots might infringe on the privacy of users. (12) But the day when we can physically experience a place on the other side of the world without actually leaving home may not be that far off.
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.

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 is crucial for understanding the river's impact on surrounding ecosystems and human activities. Option A, depth, is mentioned but not the main focus, making it less relevant. Option B, length, while significant, does not capture the central theme of the passage. Option D, location, is addressed but serves more as context rather than the primary discussion point. Therefore, width is the key aspect highlighted throughout the text.

Why is the phrase "Amerigo the discoverer" (sentence 2) placed in quotation marks?
- A. To show that it is important
- B. To indicate that it is a direct quotation from a book
- C. To question whether Vespucci really discovered America
- D. To highlight the differences between the map and the book
Correct Answer & Rationale
Correct Answer: B
The phrase "Amerigo the discoverer" is placed in quotation marks to indicate that it is a direct quotation from a book, reflecting the specific wording used by the author. This helps readers recognize that the phrase is not the writer's own interpretation but a citation from another source. Option A is incorrect because quotation marks do not inherently signify importance. Option C misinterprets the purpose of the quotation marks, as they do not imply skepticism about Vespucci's discovery. Option D is also inaccurate, as the quotation marks focus on the phrase itself rather than any differences between a map and a book.

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.

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.
