Some have argued that body size influences mating decisions throughout all societies. Their argument rests largely on self-reports of university-age students and on analyses of personal advertisements in newspapers for dating partners.

Summarize Argument
Some people conclude that body size influences mating decisions throughout all societies. This conclusion is based on self-reports of university-age students and on analyses of personal ads for dating partners in newspapers.

Identify and Describe Flaw
The argument is based on a sample that might be unrepresentative. The preferences of university-age students and people who resort to personal ads for dating partners are probably not the same as the preferences of most other people in society.

A
concludes that one kind of event causes another kind of event without ruling out the possibility that both kinds of events are the result of a third kind of event
The conclusion does not assert that one event causes another kind of event. The conclusion concerns a feature (body size) that allegedly plays a role in mating decisions. Body size is not an event. Also, the premise doesn’t present a correlation between two events.
B
bases a conclusion on a sample that may be unrepresentative of the population about which the conclusion is drawn
The conclusion, about “all societies,” is based on reports from university-age students and analyses of personal ads in newspapers. There’s no reason to think these students and people who place personal ads are similar in their preferences to people generally in all societies.
C
concludes that an effect has only one cause in the face of evidence that the effect has multiple causes
The evidence does not suggest that there are multiple factors that play a role in mating decisions. The conclusion also does not assert that body size is the only influence on mating decisions.
D
uses a claim that applies only to entire societies to draw a conclusion about individual persons
The conclusion is not about individual persons. And the evidence does not apply to “entire societies.” The evidence concerns reports from university-age students and analyses of personal ads in newspapers.
E
draws a universal conclusion on the basis of a very small number of individual cases
We don’t know that there were only a “very small number” of individual cases. The stimulus doesn’t tell us how many self-reports or personal ads the conclusion is based on.
