A recent poll of a large number of households found that 47 percent of those with a cat had at least one person with a university degree, while 38 percent of households with a dog had at least one person with a university degree. Clearly, people who hold university degrees are more likely to live in a household with a cat than one with a dog. The reasoning in the argument is flawed in that the argument ['fails to consider how many of the households have at least one person without a university degree', 'ignores the possibility that a significant number of households might have both a cat and a dog', 'takes for granted that there are not significantly more households with a dog than ones with a cat', 'ignores the possibility that two things can be correlated without being causally connected']
