Set 7: Rhetorical Synthesis (Advanced)
Explanation
PASSAGE
A student is writing about renewable energy storage. The student wants to explain the challenge of storing solar and wind power. Notes: - Solar and wind energy are intermittent—dependent on weather. - Current battery technology is expensive at grid scale. - Energy demand doesn't always match production times. - Some regions achieve 30% renewable energy usage.
Which choice most effectively uses information from the notes to accomplish the student's goal?
Detailed Answer Explanation
This question asks you to effectively combine information to achieve a goal. The goal is to explain the CHALLENGE. Intermittency, demand mismatch, and expensive batteries explain storage difficulties. 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:
• "explain the challenge"
• "intermittent—dependent on weather"
• "battery technology is expensive"
• "demand doesn't always match production"
Why others are wrong: D (Discusses popularity, not storage challenges.), C (Shows success, not challenges.), A (Discusses improvement, opposite of highlighting challenges.).
