Set 3: Command of Evidence (Intermediate)
Explanation
PASSAGE
Epigenetics studies how behaviors and environment can cause changes that affect the way genes work. Unlike genetic mutations, epigenetic changes are reversible and do not change DNA sequence. However, they can be passed to offspring, influencing gene expression across generations.
What is a key difference between epigenetic changes and genetic mutations?
Detailed Explanation
This question requires you to identify evidence that supports a claim. The text explicitly contrasts: 'Unlike genetic mutations, epigenetic changes are reversible and do not change DNA sequence.' 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:
• "reversible and do not change DNA sequence"
Why others are wrong: A (They explicitly do NOT change sequence.), B (This option is incorrect.), D (They CAN 'be passed to offspring.').
