(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 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.

The passage implies that the true cause of the bridge collapse was
- A. low-quality materials
- B. short-sighted design
- C. substandard craftsmanship
- D. unexpectedly high winds
Correct Answer & Rationale
Correct Answer: B
The passage suggests that the bridge collapse stemmed from a fundamental flaw in its design, indicating that the planning and engineering did not adequately account for structural integrity. Option A, low-quality materials, implies that the materials used were inferior, but the passage does not emphasize material quality as the primary issue. Option C, substandard craftsmanship, points to poor construction practices, yet the focus of the passage leans more toward design deficiencies rather than execution. Option D, unexpectedly high winds, suggests an external factor causing the collapse, but the passage attributes the failure to inherent design shortcomings rather than environmental conditions.

Although she had not grown up playing soccer, Jeanette was such an outstanding athlete, she scored more goals than any other member of the soccer team.
- A. athlete, she
- B. athlete, she had
- C. athlete that
- D. athlete that she
Correct Answer & Rationale
Correct Answer: D
Option D, "athlete that she," effectively introduces a defining clause that clarifies Jeanette's exceptional abilities. The word "that" connects her status as an athlete to her achievement, emphasizing the cause-and-effect relationship. Option A, "athlete, she," lacks a connector, making the sentence feel abrupt and incomplete. Option B, "athlete, she had," introduces unnecessary past tense that does not align with the context of her current achievements. Option C, "athlete that," is missing a crucial pronoun, making it grammatically incorrect. Thus, D provides the most coherent and grammatically sound structure.

Despite the difficulties he had encountered, the mountain climber had no fear when it ________ to high mountains.
- A. comes
- B. came
- C. has come
- D. had come
Correct Answer & Rationale
Correct Answer: B
Option B, "came," is appropriate here as it uses the simple past tense, which aligns with the context of the sentence about the climber's past experiences with high mountains. This tense indicates a completed action in the past, fitting well with "despite the difficulties he had encountered." Option A, "comes," is incorrect because it uses the simple present tense, which does not match the past context of the sentence. Option C, "has come," is also unsuitable since it implies a connection to the present, which does not align with the past experiences being discussed. Option D, "had come," suggests a past perfect tense that is unnecessary in this context, as the simple past suffices to convey the intended meaning.
