Self-study
Voting records regularly show that people over 65 vote in the highest percentages while young adults are least likely to vote. This indicates that citizens are becoming increasingly disconnected from the political system with each passing generation.
20.
The argument's reasoning is questionable in that the argument
a
compares an early stage of one generation to a later stage of another
The argument compares an early stage of one gen. (the young adults’ generation) to a later stage of another (the older people’s generation). This opens the possibility that the disparity in voting is due to the stage of the gen., not a difference between one gen. and another.
b
fails to take into account the relative sizes of the generations compared
The sizes of the generations are irrelevant, because the argument concerns explanations for a disparity in the likelihood of voting. People over 65 are more likely to vote than young adults. The comparative number of each group doesn’t affect how we interpret this disparity.
c
provides evidence for a phenomenon without providing an explanation of the phenomenon
The author does try to provide an explanation of the disparity in voting rates — this is the purpose of the author’s conclusion. (C) therefore doesn’t accurately describe what happens in the argument.
d
confuses the cause of an effect with the effect itself
(D) describes potential reverse causation. But it doesn’t make sense to think that one’s likelihood to vote or one’s level of political engagement could cause one to age or cause one to be part of a generation.
e
overlooks the possibility that voting patterns among age groups will change in the future
The author doesn’t overlook this possibility; in fact the author believes that each generation will be more and more politically disconnected. So the author could very well accept that for each age, future people of that age will be less likely to vote.
