What is one right guaranteed by the First Amendment?

The First Amendment of the United States Constitution guarantees several fundamental rights, one of which is the right to freedom of speech. This right ensures that individuals have the ability to express their thoughts, opinions, and ideas without fear of government censorship or punishment. This protection is foundational to the functioning of a democratic society, as it allows for a marketplace of ideas where differing viewpoints can be discussed and debated.

The other choices listed pertain to rights protected under different amendments. The right to bear arms is found in the Second Amendment, the right to a speedy trial is addressed in the Sixth Amendment, and the right against self-incrimination is part of the Fifth Amendment. While all of these rights are important, freedom of speech specifically falls under the protection of the First Amendment, making it the correct answer to the question.
