Company spokesperson: Household Products magazine claims that our Filterator X water filter does not remove chemical contaminants in significant amounts.
Conclusion (implied rebuttal conclusion)
Filterer X water filter effectively removes chemical contaminants in significant amounts.
Evidence
Millions of Filterer X owners are satisfied with the product's performance.
Evaluate
We need to challenge the spokesperson's claim that the water filter effectively removes chemical contaminants based on owner satisfaction. We can do this by highlighting that consumer satisfaction isn't necessarily linked to the filter's actual ability to remove contaminants.
Goal
Find an answer choice that demonstrates why consumer satisfaction does not reliably indicate actual contaminant removal, thus weakening the argument made by the spokesperson.
