Voting records regularly show that people over 65 vote in the highest percentages while young adults are least likely to vote.
Conclusion (this indicates that)
Citizens are becoming increasingly disconnected from the political system with each passing generation.
Evidence
People over 65 vote in the highest percentages while young adults are least likely to vote.
Evaluate
The author's evidence presents a Curious Comparison -- why is it that people over 65 have the highest percentage of voting whereas young adults have the lowest percentage of voting?
His conclusion assumes one possible Causal Explanation -- each new generation is less connected to the political system, so they don't feel as strong an urge to vote.
We always react to this Curious Fact / Explanation type of argument with the same two pressure points: - Alternative Explanations for the curious fact (how else could we explain why higher percentages of older people than younger people vote?)
- Plausibility of the Author's Explanation (do we have any other evidence that today's generation is less connected to the political system than previous generations were?)
When we see Curious Fact / Explanation arguments on Flaw, the correct answer is almost always about Alternate Explanations.
A different way to explain the voting difference between old and young might just be that the old people are retired and can watch cable news all day and have no problem voting on random Tuesdays, whereas young people are busy and have to go to work or have enough of a social life that they don't pay any attention to politics.
The conclusion isn't saying . It's saying,
Goal
Look for an answer complaining that the author failed to consider some alternate explanation for the difference in voting habits.
