Set 2: Command of Evidence

Explanation

Answer: A

PASSAGE

Chlorophyll is the pigment that gives plants their green color. It absorbs light most efficiently in the blue and red parts of the spectrum, but reflects green light. This reflected light is what our eyes perceive.

Based on the text, why do plants appear green?

A. They absorb green light for energy.✓ Correct

B. They produce green light through bioluminescence.

C. They reflect green light rather than absorbing it.

D. They absorb all colors of light equally.

Detailed Explanation

This question requires you to identify evidence that supports a claim. The text states that chlorophyll 'reflects green light' and 'this reflected light is what our eyes perceive.' The best evidence directly and explicitly supports the stated claim without requiring assumptions. Match specific textual details or data points to the claim being made. The correct answer provides clear, direct support. Strong evidence directly addresses the claim without requiring additional interpretation. When evaluating options, look for quotes or data that explicitly support the statement. Weak evidence may be tangentially related but doesn't provide direct proof.

Key Evidence:

• "reflects green light"

• "what our eyes perceive"

Why others are wrong: B (No mention of producing light.), C (This option is incorrect.), D (They absorb blue/red efficiently, not all equally.).
