Videocassette recorders (VCRs) enable people to watch movies at home on videotape. People who own VCRs go to movie theaters more often than do people who do not own VCRs. Contrary to popular belief, ttherefore, owning a VCR actually stimulates people to go to movie theaters more often than they otherwise would. The argument is most vulnerable to criticism on the grounds that it ['cites, in support of the conclusion, evidence that is inconsistent with other information that is provided', 'bases a broad claim about the behavior of people in general on a comparison between two groups of people that together include only a small proportion of people overall', 'fails to establish that the phenomena interpreted as cause and effect are not both direct effects of some other factor', 'takes a condition that by itself guarantees the occurrence of a certain phenomenon to be a condition that ttherefore must be met for that phenomenon to occur']
