Name one right guaranteed by the First Amendment.

The First Amendment of the United States Constitution guarantees several fundamental rights that are essential to a democratic society. One of these rights is the right to assemble, which protects individuals' ability to gather peacefully for various purposes, such as protests, meetings, or celebrations. This right ensures that citizens can express their views collectively and advocate for causes they believe in without fear of government repression. The protection of peaceful assembly is a critical aspect of civic engagement and democratic discourse, reflecting the broader principles of freedom of expression and association that the First Amendment embodies.

In contrast, the other options refer to rights protected by different amendments or legal provisions. The right to bear arms is guaranteed by the Second Amendment, the right to vote falls under various laws and amendments addressing voting rights (like the Fifteenth or Nineteenth Amendments), and the right to a speedy trial is ensured by the Sixth Amendment. Each of these rights plays a vital role in American democracy, but the right to assemble is specifically enshrined in the First Amendment.
