(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.

Why does the author place quotation marks around the word "patriotic" (sentence 2)?
- A. To acknowledge that Wrigley's gum, while associated with a patriotic gesture, is not actually patriotic
- B. To emphasize that Wrigley's gum helped American soldiers
- C. To show that American soldiers used the word patriotic to describe Wrigley's gum
- D. To indicate that the Wrigley Company changed the name of the product to include the word patriotic
Correct Answer & Rationale
Correct Answer: A
Quotation marks around the word "patriotic" suggest that the term is being used in a non-literal or ironic sense, indicating skepticism about its true meaning. Option A accurately reflects this by acknowledging that while Wrigley's gum is linked to a patriotic gesture, it may not genuinely embody patriotism. Option B incorrectly assumes that the emphasis is on the gum's supportive role for soldiers rather than questioning the term itself. Option C misinterprets the use of quotation marks, suggesting that soldiers coined the term, which is not the case. Option D mistakenly implies a product name change, which is irrelevant to the author's intent in using quotation marks.

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 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 1952, Dwight Eisenhower was elected President of the United States, he won 55% of the vote.
- A. he won
- B. he had won
- C. with winning
- D. winning
Correct Answer & Rationale
Correct Answer: D
The phrase "winning" effectively conveys the action of Eisenhower's election in a succinct manner, emphasizing the achievement without the need for auxiliary verbs. Option A, "he won," is grammatically correct but less fluid in this context. It shifts focus to a completed action rather than the ongoing significance of his victory. Option B, "he had won," uses the past perfect tense, which implies a prior context that isn’t necessary here and complicates the sentence unnecessarily. Option C, "with winning," introduces an awkward prepositional phrase that detracts from the clarity and directness of the statement.
