Most Strongly SupportedDiff: Medium
Logic Breakdown
Passage Summary: Breaking up large forests into small chunks creates a perfect environment for mice that carry Lyme disease, which eventually gets passed to people by ticks.
Reasoning: Forest fragmentation creates small patches where white-footed mice thrive, and these mice are the primary carriers of Lyme disease bacteria, which ticks then transmit to humans.
Analysis: In this 'Most Strongly Supported' scenario, we are looking for a logical inference that connects the dots between the provided facts. We know that fragmentation leads to more mice, and more mice lead to a higher prevalence of the bacteria that cause Lyme disease. Therefore, it is highly likely that human populations living near fragmented forests face a higher risk of contracting the disease. Look for an answer that establishes this causal link between environmental changes and public health risks.

Correct Answer
D
If fragmentation elevates the main carrier’s density and Lyme disease is often transmitted to humans via ticks that obtain the bacteria from these mice, then efforts to stop fragmentation can reduce risk and thus can have a beneficial effect on human health. The phrasing “can have” is appropriately cautious.
