The statement that best analyzes how Lemon v. Kurtzman clarified the meaning of the First Amendment is:
It set the standard for what it meant for government to violate the Establishment Clause.
This case established the Lemon Test, which is used to determine whether a law or government action violates the Establishment Clause by evaluating if it has a secular purpose, does not advance or inhibit religion, and does not result in excessive government entanglement with religion.
