Which of the following issues did the Bill of Rights leave unresolved? Whether individual states can establish a religion Whether the federal government can regulate a religion Whether individual states can require a religious test or oath Whether the federal government can control a religion in the military

Whether individual states can require a religious test or oath

Explanation:

The Bill of Rights protected the right to freedom of religion for public officials, stipulating that no public official should be subjected to a religious test or oath, but that he should swear an oath to the constitution. It also prohibited the federal government from establishing these tests or oaths to the population. However, the Bill of Rights did not impose this same ban on individual states, and many of them imposed religious tests and oaths for holding public offices, limiting individuals who could or might not hold those offices.
