(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.
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.

The historic town library is just passed the intersection of Main Street and the more residential Frederick Street.
- A. passed
- B. pass
- C. past
- D. passing
Correct Answer & Rationale
Correct Answer: C
In this context, "past" is the appropriate choice as it refers to a location beyond a point—in this case, the intersection. - **A: passed** is the past tense of "pass," which does not fit the sentence's need for a preposition indicating location. - **B: pass** is the base form of the verb and does not convey the intended meaning of being beyond the intersection. - **D: passing** suggests an ongoing action, which is not suitable here as the sentence describes a static location relative to the intersection. Thus, "past" effectively communicates that the library is located beyond the intersection.

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.

The author of Passage 1 would probably say that the claims in the last sentence of Passage 2 ("Someday... notice") are
- A. disappointing and inaccurate
- B. stimulating and insightful
- C. optimistic but vague
- D. alarming but truthful
Correct Answer & Rationale
Correct Answer: A
The claims in the last sentence of Passage 2 are likely viewed as disappointing and inaccurate because they may contradict the author's perspective in Passage 1, which emphasizes realism over idealism. Option B, "stimulating and insightful," misinterprets the author's critical stance; the claims are not presented as thought-provoking. Option C, "optimistic but vague," overlooks the author's likely skepticism towards vague claims that lack concrete support. Option D, "alarming but truthful," fails to capture the author's likely rejection of the claims as factual, indicating a more critical viewpoint.

The retired government official spoke_______ about foreign policy and international trade.
- A. as knowing
- B. in knowledge
- C. knowledgeably
- D. knowledgeable
Correct Answer & Rationale
Correct Answer: C
Option C, "knowledgeably," is the appropriate choice as it is an adverb that describes how the retired government official spoke, indicating that he did so with knowledge and expertise. Option A, "as knowing," is grammatically incorrect in this context; it does not fit the structure of the sentence. Option B, "in knowledge," is awkward and does not function as an adverb, failing to appropriately modify the verb "spoke." Option D, "knowledgeable," is an adjective and does not correctly modify the verb, making it unsuitable for this sentence structure.
