Flawed ReasoningDiff: Easy
Logic Breakdown
Passage Summary: A study found that only 35 people said they went to the doctor for headaches, but the doctors' records showed 105 headache appointments. The author concludes the patients must have forgotten their visits.
Conclusion: Many residents who visited a doctor for severe headaches must have forgotten that they did so.
Reasoning: A survey of residents found only 35 people reported seeking help for headaches, but medical records showed 105 total consultations for that condition.
Analysis: The author is falling for a classic 'units of measurement' trap by confusing the number of *people* with the number of *visits*. It is entirely possible that the 35 people who reported going to the doctor simply went an average of three times each, which would perfectly account for the 105 consultations. To identify the flaw, look for an answer that points out the author's failure to consider that a single person can account for multiple medical appointments. It's a bit like assuming 100 meals served at a restaurant means 100 different people ate there—some people just really like seconds.

Correct Answer
C
It points out the overlooked possibility that some people had more than one visit for the same condition, so 105 consultations need not involve more than 35 patients. This undermines the claim that many residents must have forgotten their visits.
