Summarize Argument: Counter-Position
Certain researchers concluded that, on average, 50-year-olds are more altruistic than 20-year-olds. This conclusion was based on a study in which twice as many 50-year-olds as 20-year-olds, out of a sample of 100 of each group, reported sometimes donating blood.
The author concludes that there’s reason to be skeptical of the researchers’ conclusion. This is because many people hesitate to admit that their behavior doesn’t fit what society expects. (The implication is that there’s another explanation for the disparity in reported blood donations.)

Describe Method of Reasoning
The author presents an alternative hypothesis to explain the disparity in reported blood donations. Maybe the 50-year-olds exaggerated?
A
showing that the data are based on an unrepresentative sample
There’s no comment about the background/features of people who were part of the study. What the author’s suggesting is that we can’t trust the “reports.” This doesn’t mean the samples were unrepresentative.
B
offering an alternative explanation of some of the data
The author suggests that one reason the 50-year-olds might have reported donating blood at a higher rate than the 20-year-olds reported doing so is that many 50-year-olds might not have wanted to admit that they didn’t donate.
C
showing that one cannot directly observe altruism
The author could believe that it’s possible to directly observe altruism (for ex., we see someone give away a ton of money for free). The author doesn’t show that this is impossible to observe. What she suggeests is that some 50-year-olds might be lying about donating blood.
D
criticizing the motives of the researchers
The author doesn’t say anything about the motives of the researchers. She simply comments on an alternative explanation for the results of the study.
E
offering a specific counterexample
The author doesn’t bring up a 50-year-old who didn’t donate, or a 20-year-old who did. (These aren’t “counterexamples” anyway, since you can’t have a counterexample to an average or a general tendency, which already allow for exceptions.)
