Self-study
In a recent study, a group of subjects had their normal daily caloric intake increased by 25 percent. ████ ████████ ███ ████████ ██ ███ ████ ██ ████████ ███████ █████ ██ ███████ ████████ ███ ███████ ███████ ████████████ ███████ ██ ██ ███████ ██ █████ ██████ █████ ███████ ███████ ███ ████████ ██████ ████ ███ ████ ███ ██████ ██ ███ ██████ ███ ███ ██████ ██ ████ ███ ██████ ███ ███ ████ ███ ████ ███████
Summary
One group of subjects increased their daily caloric intake by 25 percent solely by consuming alcohol. Another group of subjects, instead of increasing their caloric intake, substituted 25 percent of their existing caloric intake solely by consuming alcohol. All subjects gained body fat, and the amount of body fat gained was the same for both groups.
Strongly Supported Conclusions
The number of calories a person consumes is not the only factor contributing to body fat gain.

Which one of the following ██ ████ ████████ █████████ ██ ███ ███████████ ██████
a
Alcohol is metabolized ████ ███████ ██ ███ ████ ████ ███ █████ █████ ██ ███████
This answer is unsupported. We don’t know from the stimulus how quickly alcohol is metabolized. Moreover, we don’t know from the stimulus how different rates of metabolization affect a person’s amount of body fat.
b
In the general ███████████ ███████ ██ ███ ███████ █████ ██ █████ ██ ████ ████
This answer is unsupported. We don’t know from the stimulus whether alcohol is the primary cause. We know that it may be a cause, but to say it is the primary cause is too strong.
c
An increased amount ██ ████ ███ ████ ███ ███████████ █████ █ ██████ █████
This answer is unsupported. The stimulus does not mention the weight of any of the people in the groups. The stimulus solely focuses on amount of body fat, which may or may not correlate with weight gain.
d
Body fat gain ██ ███ █████████ ██████ ██ ███ ██████ ██ ████████ ███ █████████
This answer is strongly supported. The first group increased their caloric intake and the second group’s caloric intake remained the same yet both groups gained body fat. Therefore, body fat gain is not dependent solely on a person’s caloric intake.
e
The proportion of ████████ ████ ███████ ██ █ ████ ██ ████ ███████████ ███ ████ ███ ████ ████ ███ ███ █████ ████████ ████ ████████
This answer is anti-supported. Both groups in the stimulus gained the same amount of body fat.
