Logic Breakdown
Passage Summary: A company president claims a new medical waste facility won't pollute the area because the waste itself is thoroughly disinfected by steam during the process.
Conclusion: The sterilization plant will not cause any pollution in the surrounding neighborhood.
Reasoning: The medical waste processed by the plant is sterile and cleaner than food from a clean kitchen after being treated with superheated steam.
Analysis: The president's argument contains a classic 'scope' error by focusing entirely on the cleanliness of the end product while ignoring the process itself. Even if the waste comes out pristine, the act of running the plant—using superheated steam, heavy machinery, or chemical byproducts—could still release pollutants into the air or water. For this argument to hold water, we must assume that the sterilization process itself doesn't generate its own pollution. Look for an answer that bridges this gap by asserting that the plant's operation is as clean as its output.

Unlock Full Passage14.The president's argument depends on which one of the following assumptions?
Correct Answer
B
The president assumes away pollution risks before sterilization. Negation test: if handling the waste before treatment does pose a pollution threat, then the plant’s operation could cause pollution, directly undermining the conclusion. So this assumption is necessary.
