Flawed Parallel ReasoningDiff: Hardest
Logic Breakdown
Passage Summary: Since plants grow better with more carbon dioxide and factories produce carbon dioxide, the author concludes that industrial pollution is a 100% good thing for farming.
Conclusion: Industrial activities, such as burning fossil fuels, are entirely helpful to the agricultural sector and its dependents.
Reasoning: Industrial activities increase atmospheric carbon dioxide, and studies show that higher carbon dioxide levels accelerate the process of photosynthesis in plants.
Analysis: This argument is a classic example of 'tunnel vision' logic. It identifies a single positive correlation—more CO2 equals faster photosynthesis—and uses it to claim the entire cause is 'purely beneficial,' conveniently ignoring any potential negative side effects like climate change or toxic runoff. To find the parallel, look for an answer choice that takes one narrow benefit of a complex phenomenon and concludes that the phenomenon is exclusively good, ignoring any possible downsides.

Correct Answer
B
It mirrors the structure: because exercise prevents various ills, it concludes no harm, and lots of good, can come from exercise. That is the same leap from “some benefits” to “purely beneficial.”
