The argument suggests that the increase in voter turnout among individuals aged 18 to 25 in the 2004 local election was due to candidates making more of an effort to appeal to these younger voters. To weaken this argument, we need to find information that suggests an alternative reason for the increase in turnout. Let's evaluate each of the answer choices:
A. The candidates for city council were ages 55, 72, and 64.
- This information does not directly address the increase in voter turnout among individuals aged 18 to 25. It focuses on the candidates' ages, which may not be relevant to the argument.
B. The turnout among voters between the ages of 35 and 44 was 42% in 2004.
- This information provides data about a different age group (35 to 44), which is not directly related to the 18 to 25 age group mentioned in the argument. It doesn't weaken the argument.
C. Turnout among African-Americans between 18 and 25 decreased from 2000 to 2004.
- This information is relevant to the 18 to 25 age group mentioned in the argument, but it doesn't necessarily weaken the argument. It suggests a decrease in turnout among a specific subgroup, but it doesn't explain the overall increase in turnout or provide an alternative reason for it.
D. The polls stayed open later on Election Day in 2000.
- This information relates to the 2000 election, not the 2004 election mentioned in the argument. It doesn't address the increase in voter turnout in 2004 and doesn't weaken the argument.
E. In 2004, a referendum on lowering the legal age for purchasing alcohol to 18 was on the ballot.
- This information is relevant to the 2004 election and the age group in question (18 to 25). It provides an alternative reason for the increase in turnout in 2004, as the presence of such a referendum might have motivated more young people to vote. Therefore, it weakens the argument by suggesting another cause for the higher turnout.
So, the correct answer is (E) because it provides an alternative explanation for the increase in voter turnout among individuals aged 18 to 25 in the 2004 local election.
