Set 15: Rhetorical Synthesis (Advanced)

Explanation

Answer: A

PASSAGE

A student is writing about bioluminescence. The student wants to explain how organisms use light for survival. Notes: - Some fish use light to attract prey in dark ocean depths. - Fireflies flash to attract mates. - Certain squid produce light to camouflage against ocean surface light. - Bioluminescence is caused by chemical reactions in organisms.

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

A. Organisms harness bioluminescence for survival in diverse ways: deep-sea fish lure prey with light, fireflies flash to attract mates, and some squid use it for camouflage.✓ Correct
B. Bioluminescence is produced by chemical reactions within living organisms.
C. Deep-sea environments are completely dark, requiring unique adaptations.
D. Bioluminescence occurs in many species across different ecosystems.

Detailed Answer Explanation

This question asks you to effectively combine information to achieve a goal. The goal is how organisms USE light for survival. Luring prey, attracting mates, and camouflage are survival uses. 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:

• "how organisms use light for survival"

• "attract prey"

• "Fireflies flash to attract mates"

• "camouflage"

Why others are wrong: B (Explains cause of bioluminescence, not survival uses.), D (States distribution but not specific survival uses.), C (Not directly in notes; describes environment, not light uses.).
