(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.

Why does the author mention that only men signed the Mayflower Compact?
- A. To show the similarities between the Compact and the Constitution
- B. To suggest that the Compact was not a perfect model of government
- C. To indicate that men were better lawmakers than women
- D. To imply that only men were on board the Mayflower
Correct Answer & Rationale
Correct Answer: B
The mention of only men signing the Mayflower Compact highlights the limitations of this early governance document, suggesting it was not a perfect model of government. It reflects the societal norms of the time, where women's voices were excluded from formal political processes, indicating a lack of representation. Option A incorrectly suggests a direct comparison with the Constitution, which is not the focus. Option C perpetuates a gender bias that is not supported by the text. Option D misinterprets the context; while only men signed, it does not imply that only men were aboard the Mayflower, as historical records show women were present as well.

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.

The author uses a direct quotation (sentence 4) to
- A. present a skeptical opinion about Ardi
- B. provide eyewitness testimony about Ardi
- C. place Ardi in the context of other discoveries
- D. give a physical description of Ardi
Correct Answer & Rationale
Correct Answer: C
The use of a direct quotation in sentence 4 serves to place Ardi within the broader context of other significant discoveries, highlighting its relevance and importance in the field. This contextualization helps readers understand Ardi's significance in relation to other findings. Option A is incorrect; the quotation does not express skepticism but rather situates Ardi among other discoveries. Option B is also wrong, as the quotation does not provide firsthand eyewitness testimony. Lastly, option D is misleading; the quotation does not focus on a physical description of Ardi but emphasizes its contextual importance.

In sentence 8 (reproduced below), which of the following best replaces 'they'? Rather than commuting long distances, they can use their home computers to maneuver simple wheeled robots around the head office
- A. high-tech engineers
- B. remote workers
- C. sophisticated robots
- D. employers
Correct Answer & Rationale
Correct Answer: B
Option B, "remote workers," accurately identifies the subject who would benefit from using home computers to control robots instead of commuting. This term directly relates to individuals who work from home, aligning with the context of the sentence. Option A, "high-tech engineers," is too specific and does not encompass all individuals who might work remotely. Option C, "sophisticated robots," incorrectly refers to machines rather than people, making it irrelevant in this context. Option D, "employers," shifts the focus from the workers to those who manage them, which does not fit the intended meaning of the sentence.
