Passage Summary: People with VCRs go to the movies more than people without them, so the author concludes that the VCR is what's making them go to the movies more.

Conclusion: Owning a VCR causes people to attend movie theaters more frequently than they would otherwise.

Reasoning: There is a statistical correlation showing that people who own VCRs go to movie theaters more often than people who do not own them.

Analysis: This is a classic case of confusing correlation with causation. The author observes two things happening together—VCR ownership and theater attendance—and assumes the first causes the second. In the world of social dynamics, it's just as likely that a third factor, like being a 'movie buff,' causes a person to both buy a VCR and go to the theater. Look for an answer that identifies this failure to consider alternative causes or the possibility that the causal relationship is reversed.
