Set 6: Cross-Text Connections
Explanation
PASSAGE
Text 1 Epigenetics is the study of how behaviors and environment can cause changes that affect the way your genes work. Unlike genetic changes, epigenetic changes are reversible and do not change your DNA sequence. Text 2 Lamarckism, a discredited theory, proposed that organisms can pass on traits acquired during their lifetime to offspring. Interestingly, some epigenetic markers can be heritable, suggesting that Lamarck was not entirely wrong, though the mechanism is different.
How does the modern discovery in Text 1 relate to the historical theory in Text 2?
Detailed Answer Explanation
This question asks you to compare perspectives from two passages. Text 1: Epigenetics (Env affects gene work). Text 2: Lamarck (Acquired traits heritable). Epigenetics = Heritable acquired traits today. Relation: Partial validation. Understanding how the authors relate to each other's views is essential. Identify whether they agree, disagree, or address different aspects of the topic. Focus on their specific claims and conclusions. When comparing texts, first identify each author's thesis or main argument. Then determine how these positions interact: do they complement each other, contradict each other, or address different aspects of the same issue? The relationship between texts reveals deeper meaning.
Key Evidence:
• "markers can be heritable"
• "Lamarck was not entirely wrong"
Why others are wrong: B (Mechanism different.), A (Doesn't change DNA.), D (Explicit link.).
