Set 15: Rhetorical Synthesis (Advanced)

Explanation

Answer: D

PASSAGE

A student is writing about black holes. The student wants to explain what happens to objects near a black hole. Notes: - Black holes have gravity so strong that nothing can escape. - The event horizon marks the point of no return. - Objects are stretched by gravitational forces (spaghettification). - Black holes form from collapsed massive stars.

Which choice most effectively uses information from the notes to accomplish the student's goal?

A. Scientists have recently captured the first image of a black hole.
B. Black holes form when massive stars collapse at the end of their life cycle.
C. Black holes are among the most mysterious objects in the universe.
D. Objects approaching a black hole are stretched by intense gravitational forces, and once past the event horizon—the point of no return—nothing can escape the black hole's gravity.✓ Correct

Detailed Answer Explanation

This question asks you to effectively combine information to achieve a goal. The goal is what happens to OBJECTS near black holes. Stretching, event horizon, and no escape describe this. The correct synthesis will use relevant details from the notes in a logical, purposeful way. Focus on what the question asks you to accomplish, then choose the answer that best achieves that goal using the provided information. Effective synthesis requires selecting and combining the most relevant information to achieve a specific purpose. Not all provided notes may be equally useful. Focus on what best accomplishes the stated goal while maintaining logical coherence.

Key Evidence:

• "what happens to objects near a black hole"

• "gravity so strong that nothing can escape"

• "event horizon marks the point of no return"

• "Objects are stretched"

Why others are wrong: B (Explains formation, not what happens to objects nearby.), A (Not in notes; discusses observation, not object behavior.), C (General statement; doesn't explain object behavior.).
