Questions: The Supreme Court has struck down a. Bible readings in school b. meditation in school c. prayer in school d. a moment of silence in school

The answer is c. prayer in school

The Supreme Court has addressed the issue of Bible readings in public schools, particularly in the case of Abington School District v. Schempp (1963), where it ruled that mandatory Bible readings in public schools were unconstitutional. However, this is not the most commonly referenced case when discussing the prohibition of religious activities in schools.

Meditation, when practiced in a secular manner, has not been struck down by the Supreme Court. The Court's decisions have focused more on religious activities rather than secular practices like meditation.

The Supreme Court has specifically ruled against organized prayer in public schools in the landmark case Engel v. Vitale (1962). This decision held that it is unconstitutional for state officials to compose an official school prayer and encourage its recitation in public schools.

The Supreme Court has addressed moments of silence in schools, particularly in Wallace v. Jaffree (1985). The Court struck down an Alabama law that mandated a moment of silence for "meditation or voluntary prayer" because it was seen as an endorsement of religion. However, moments of silence that are genuinely neutral and not intended to promote prayer have not been universally struck down.
