Logic Breakdown
Passage Summary: A biologist noticed butterflies are moving north as the weather gets warmer in the north, so she thinks the warming weather is what's making them move.
Conclusion: The shift in global climate is the cause of the checkerspot butterfly's northward migration.
Reasoning: There is a near-perfect correlation between the butterflies' movement and the northward shift of warm climate zones.
Analysis: This is a causal argument based on a correlation, which is always a bit risky in the world of logic. To strengthen the claim that climate causes the move, we want to eliminate other causes or show the correlation holds up in other ways. Since this is an 'EXCEPT' question, four answers will help prove the climate is the culprit, while the correct one will either be irrelevant or actually weaken the link. Look for an answer that doesn't provide a reason to believe climate is the specific driver of this butterfly migration.

Correct Answer
C
If the checkerspot butterfly can adapt easily to a wide range of temperatures and geographic conditions, then temperature shifts would be less likely to drive its distribution. That undercuts rather than supports the climate-based explanation, so it is the EXCEPT.
