Passage Summary: A researcher notices that people with certain mental health issues have specific brain waves. Since watching TV also triggers those brain waves, the researcher claims TV causes the mental health issues.

Conclusion: The researcher concludes that excessive television viewing increases the likelihood of developing a personality disorder.

Reasoning: Personality disorders are associated with higher levels of theta brain waves, and watching television is shown to increase those same brain waves.

Analysis: Analyze the gap between the premise and the conclusion. The argument commits a classic correlation-causation error by assuming that because two things share a symptom (theta waves), one must cause the other. It also fails to consider that the brain waves might be a result of the disorder rather than the cause. Look for an answer that points out the mistake of treating a shared characteristic as proof of a causal link.
