The two correct answers about the assumptions a writer can make about the audience for this essay are:
- They are mostly teenagers.
- They have a range of opinions about voting.
These assumptions align with the context of the essay prompt, which focuses on the importance of registering to vote when individuals turn 18, suggesting the audience is likely to include young people who are approaching or have recently reached voting age. Additionally, given the topic of voting, it's reasonable to assume that the audience may hold varying perspectives on the issue.
