Question

read the excerpt from chapter two of windows to the universe: revolutions in astronomy.

in this model, the sun was at the center of the solar system, and earth, along with other planets, orbited around it (this idea was revolutionary, but it wasnt brand new-remember aristarchus?).

why does the author most likely ask
emember aristarchus\?

• to create a transition between the discussion of historical models and new contributions
• to emphasize the importance of revisiting prior knowledge to understand ideas
• to remind the reader that aristarchus was mentioned in the previous chapter
• to connect earlier information about aristarchus to the new idea being introduced

Explanation:

Analyze the context of the quote

The excerpt states: "In this model, the sun was at the center of the solar system, and Earth, along with other planets, orbited around it (this idea was revolutionary, but it wasn't brand new—remember Aristarchus?)."

Evaluate the author's purpose

The parenthetical remark "remember Aristarchus?" directly follows the assertion that the heliocentric model "wasn't brand new." This rhetorical question prompts the reader to recall previously introduced information about Aristarchus (who proposed a heliocentric model in antiquity) and link it to the "new" revolutionary model being discussed in Chapter Two.

Compare with the options

• Option 1 suggests a transition between historical models and new contributions, which is too broad.
• Option 2 focuses on "revisiting prior knowledge to understand ideas," which is overly generalized.
• Option 3 mentions reminding the reader he was in the "previous chapter," which is a mechanical detail rather than the primary rhetorical purpose of connecting the ideas.
• Option 4, "to connect earlier information about Aristarchus to the new idea being introduced," directly explains why the author prompts the reader's memory at this specific moment to show the idea is not brand new.

Answer:

• to create a transition between the discussion of historical models and new contributions
• to emphasize the importance of revisiting prior knowledge to understand ideas
• to remind the reader that Aristarchus was mentioned in the previous chapter
• to connect earlier information about Aristarchus to the new idea being introduced (Correct answer)
