Flawed ReasoningDiff: Hard
Logic Breakdown
Passage Summary: A game show host claims humans and apes are equally good at investing because a single chimp beat five professionals in a one-month contest.
Conclusion: Humans are no more proficient at investing than apes are.
Reasoning: In a one-month experiment involving five stock analysts and one chimpanzee, the chimpanzee achieved a higher return on investment than any of the humans.
Analysis: This argument is a masterclass in drawing a massive conclusion from a tiny, unrepresentative sample. The host ignores the possibility that the chimp simply got lucky over a very short period, which is hardly enough time to judge investment skill. Since this is an 'EXCEPT' question, four choices will correctly identify these logical blunders, such as the small sample size or the failure to consider long-term trends. It's like saying a toddler is a better driver than a professional because the toddler won a single round of Mario Kart.

Correct Answer
B
The host’s claim compares outcomes (returns). It does not require showing that chimpanzees understand stock reports or make reasoned decisions; random picking could still yield high returns. Thus, the lack of evidence about chimp cognition is not a flaw in the host’s argument, making B the EXCEPT.
