A more thorough explanation:

The Exercise Clause, also known as the Free Exercise Clause, is a provision in the United States Constitution (Amendment I) that prohibits the government from interfering with people's religious practices or forms of worship.

For example, if a person's religion requires them to wear a certain type of clothing or head covering, the government cannot make a law that prohibits them from doing so. Similarly, the government cannot force someone to participate in a religious activity that goes against their beliefs.

The Exercise Clause is important because it protects people's freedom to practice their religion without fear of government interference or persecution.
