According to the official results of last week’s national referendum, 80 percent voted in favor of the proposal. But those results must be rigged. Everyone I know voted against the proposal, which is clear evidence that most people voted against it.

Summarize Argument
The author concludes that the results of last week’s referendum must be rigged. The results indicated that 80 percent voted in favor of the proposal. But the author believes most people must have voted against it, because everyone the author knows voted against it.

Identify and Describe Flaw
The author overlooks the possibility that the people the author knows are not representative of the people who voted in the national referendum.

A
The argument uses evidence drawn from a sample that is unlikely to be representative of the general population.
The author relies on evidence concerning how the people he knows voted. But there’s no reason to believe that the people the author knows are representative of the voters in the national referendum.
B
The argument presumes the truth of the conclusion that it sets out to prove.
(B) describes circular reasoning. But the author’s conclusion — that the results are rigged — is not a restatement of the premise, which is that everyone the author knows voted against the proposal.
C
The argument rejects a claim by attacking the proponents of the claim rather than addressing the claim itself.
There are no proponents of a claim that the results of the referendum aren’t rigged.
D
The argument fails to make a needed distinction between how people should have voted and how they actually voted.
Nothing in the argument concerns how people “should” have voted. The author doesn’t argue that people should have voted for or against the proposal.
E
The argument defends a claim solely on the grounds that most people believe it.
The author does not state that most people believe the results are rigged. So the author does not support his conclusion on the grounds that most people believe it.
