In Stone V

In Stone v. Graham (1980) , the Supreme Court ruled that

A) a Kentucky law requiring that the Ten Commandments be posted in all public schools violated the establishment clause.
B) an Alabama law authorizing a one-minute period of silence for voluntary prayer in the public schools was constitutional.
C) because the State Board of Regents in New York had written a nondenominational prayer, it could be used in the public school classrooms at the start of each day.
D) student­led prayer, using the school's public address system, before public school sporting events was constitutional.
E) churches or other religious groups cannot run schools.
