(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.

What is the passage primarily discussing?
- A. The achievement of Richard Pearse
- B. The problems of early airplanes
- C. The first flight in the United States
- D. The history of long-distance flight
Correct Answer & Rationale
Correct Answer: A
The passage primarily discusses the achievement of Richard Pearse, highlighting his significant contributions to aviation. His pioneering efforts are central to the narrative, showcasing his innovations and milestones. Option B focuses on the problems of early airplanes, which, while relevant, does not capture the primary focus on Pearse's accomplishments. Option C mentions the first flight in the United States, a separate historical event that is not the main topic of the passage. Option D addresses the broader history of long-distance flight, which encompasses many figures and events, but does not specifically center on Pearse's individual achievements.

The author of Passage 2 would most likely say that the opinion held by the "people" mentioned in the third sentence of Passage 1 ("Some people have declared") is
- A. accurate
- B. unsupported
- C. misguided
- D. amusing
Correct Answer & Rationale
Correct Answer: A
The opinion held by the "people" in Passage 1 is deemed accurate, as the author of Passage 2 likely aligns with the sentiment expressed. This suggests a shared understanding or validation of the viewpoint. Option B, "unsupported," is incorrect because the author likely provides evidence or reasoning that bolsters the opinion. Option C, "misguided," does not align with the author's perspective, which would not characterize the opinion as erroneous. Option D, "amusing," is inappropriate as it trivializes the opinion rather than acknowledging its validity.

The author of the passage does which of the following?
- A. Relates a personal anecdote
- B. Provides statistical data
- C. Quotes a named authority
- D. Challenges an official view
Correct Answer & Rationale
Correct Answer: C
The author quotes a named authority to lend credibility to their argument, enhancing the passage's persuasive impact. This approach allows the reader to see the author's position supported by established expertise. Option A is incorrect as there is no personal anecdote shared; the focus remains on authoritative sources. Option B is not applicable since the passage lacks statistical data, relying instead on qualitative support. Option D is also wrong; the author does not challenge an official view but rather reinforces their argument through the cited authority, maintaining a respectful stance towards existing perspectives.

What assumption does the author of the passage make?
- A. Gases produced by algae will be cheaper to produce than other gases.
- B. The Department of Energy is already using hydrogen-producing algae as a source of energy
- C. Mutant versions of algae will not be capable of the process of photosynthesis
- D. Readers do not associate the Department of Energy with algae research.
Correct Answer & Rationale
Correct Answer: D
The assumption that readers do not associate the Department of Energy with algae research suggests a gap in public awareness that the author aims to address. This perspective is crucial for framing the significance of the research discussed. Option A is incorrect as it makes a specific economic claim not supported by the passage. Option B incorrectly assumes the Department of Energy is currently using hydrogen-producing algae, which is not established in the text. Option C presumes that mutant algae cannot photosynthesize, but the passage does not provide evidence or context to support this claim. Thus, D accurately reflects the author's underlying assumption about public perception.
