Set 4: Rhetorical Synthesis

Explanation

Answer: A

PASSAGE

A student is writing about earthquakes. The student wants to explain what causes them. Notes: - Earthquakes occur along fault lines where tectonic plates meet. - Plates slowly move and build up pressure over time. - When plates suddenly slip, energy is released as seismic waves. - The Richter scale measures earthquake magnitude.

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

A. Earthquakes occur when tectonic plates at fault lines, having built up pressure over time, suddenly slip and release energy as seismic waves.✓ Correct
B. Scientists can now detect seismic activity around the world.
C. The Richter scale is used to measure the strength of earthquakes.
D. Earthquakes can cause significant damage in populated areas.

Detailed Answer Explanation

This question asks you to effectively combine information to achieve a goal. The goal is what CAUSES earthquakes. Plate movement, pressure buildup, and sudden slipping explain the cause. 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 what causes them"

• "tectonic plates meet"

• "build up pressure"

• "suddenly slip, energy is released"

Why others are wrong: B (Discusses detection, not cause.), C (Explains measurement, not cause.), D (Discusses effects, not cause.).
