QUESTION: 35

Nutritionist: Recent studies show that the height of the average American has increased 2 inches in the past 10 years, lending support to the view that modern foods stimulate growth. The argument would be strengthened by pointing out that

statistical studies were done on which foods were eaten
modern foods are unhealthy
all average heights are increasing
comparisons have been studied in control groups
there is no such thing as an average American

Answer(s): D

Explanation:

Options [modern foods are unhealthy] and [there is no such thing as an average American] weaken the argument, option [statistical studies were done on which foods were eaten] repeats the argument, and [all average heights are increasing] makes no sense, since" average height" is a single composite of all heights.

QUESTION: 36

Nutritionist: Recent studies show that the height of the average American has increased 2 inches in the past 10 years, lending support to the view that modern foods stimulate growth.

This argument would be weakened most by pointing out that

statistics don't lie
there are too many variables in this type of study
the generic background of the subjects was not investigated
the sample group used was small
some people's height decreased

Answer(s): B

Explanation:

Pointing out that "there are too many variables in this type of study" weakens the argument tremendously, because isolating the reason for the growth increase now becomes very difficult. Thus, we could not deduce that modern foods stimulate growth.
Option [the sample group used was small] is close, as it also weakens the argument, but it isn't specific enough. If [the sample group used was small] were "too small," then it would be an excellent answer.
