Set 7: Rhetorical Synthesis (Intermediate)

Explanation

Answer: D

PASSAGE

A student is writing about soil health. The student wants to explain the consequences of soil degradation for food security. Notes: - 33% of global soils are degraded. - Degraded soil produces lower crop yields. - Soil formation takes centuries; loss happens quickly. - Healthy soil stores carbon and helps regulate climate.

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

A. Soil forms very slowly over centuries but can be degraded rapidly.
B. Healthy soil stores carbon and plays an important role in climate regulation.
C. Sustainable farming practices can help protect soil health.
D. With 33% of global soils already degraded and producing lower crop yields, food security is threatened—especially since soil takes centuries to form but can be destroyed quickly.✓ Correct

Detailed Answer Explanation

This question asks you to effectively combine information to achieve a goal. The goal is consequences for FOOD SECURITY. Degradation extent, lower yields, and irreversibility (centuries to form) explain food security threat. 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:

• "consequences of soil degradation for food security"

• "33% of global soils are degraded"

• "lower crop yields"

• "takes centuries; loss happens quickly"

Why others are wrong: A (States formation/loss timing but not food security link.), C (Not in notes; suggests solution, not consequences.), B (Discusses climate role, not food security.).
