(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 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 highlights its significance in navigation and ecology. Option A, depth, is not the main topic; while depth may be mentioned, it does not receive the same level of attention. Option B, length, is also a lesser focus, as the passage does not delve into the river's overall distance. Option D, location, is addressed but serves more as context rather than the central theme. Thus, width emerges as the key aspect discussed in the passage.

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.

In context, which of the following is the best way to revise and combine sentences 9 and 10 (reproduced below)? These robots are equipped with cameras and video screens. The robots allow the home-bound workers to attend meetings and interact more personally with their coworkers.
- A. These robots, while being equipped with cameras and video screens, allow the home-bound workers to attend meetings, interact more personally with their coworkers
- B. These robots are equipped with cameras and video screens, moreover, they allow the home-bound workers to attend meetings and interact more personally with their coworkers.
- C. Equipped with cameras and video screens, these robots allow the home-bound workers to attend meetings and interact more personally with their coworkers.
- D. In order to allow the workers to attend meetings and interact more personally with their coworkers, these robots are equipped with cameras and video screens
Correct Answer & Rationale
Correct Answer: C
Option C effectively combines the two sentences by starting with a participial phrase, "Equipped with cameras and video screens," which succinctly conveys essential information about the robots while maintaining clarity. This structure emphasizes the robots' capabilities and their purpose in a streamlined manner. Option A introduces unnecessary complexity with "while being," making the sentence less direct and harder to follow. Option B uses "moreover," which is inappropriate for connecting the two ideas and creates a run-on sentence that disrupts the flow. Option D alters the focus by suggesting that the robots are equipped solely for the purpose of allowing interaction, which misrepresents the original intent and adds unnecessary wording.

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.
