Answer:
D) a more informed society is considered one long-term result of the constitutional protection of free speech. The First Amendment of the US Constitution guarantees the right to free speech, which has helped promote the exchange of ideas and opinions, and has allowed individuals to express their views and challenge the status quo without fear of retribution. This has led to a more diverse and informed society, where a wide range of viewpoints and opinions are expressed and debated, contributing to a more robust democracy.
