Set 4: Cross-Text Connections (Advanced)
Explanation
PASSAGE
Text 1 Antibiotic resistance is driven by natural selection. When bacteria are exposed to drugs, the susceptible ones die, leaving behind those with mutations that allow them to survive. These survivors then multiply. Text 2 Horizontal gene transfer accelerates this process. Bacteria can swap genetic material, including resistance genes, with their neighbors. This means a harmless bacterium can acquire resistance from a dangerous one without waiting for a new mutation.
How does Text 2 amplify the threat described in Text 1?
Detailed Answer Explanation
This question asks you to compare perspectives from two passages. Text 1: Selection/Mutation (Vertical). Text 2: Swap genes (Horizontal). Acceleration: Don't wait for mutation -> Faster spread. 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:
• "accelerates this process"
• "without waiting for a new mutation"
Why others are wrong: A (Bacteria.), C (Resistance.), D (Text 1 says they do.).
