Research indicates that 90 percent of extreme insomniacs consume large amount of coffee. Since Tom drinks a lot of coffee, it is quite likely that he is an extreme insomniac. Which one of the following most accurately describes a flaw in the argument's reasoning? ['It draws an inference about one specific individual from evidence that describes only the characteristics of a class of individuals', 'It fails to consider the possible contribution to extreme insomnia of other causes of insomnia besides coffee.', 'It fails to acknowledge the possibility that Tom is among the 10 percent of people who drink large amounts of coffee who are not extreme insomniacs.', 'It relies on evidence that does not indicate the frequency of extreme insomnia among people who drink large amounts of coffee.']
