McGrath, that must have been a pretty brief glance. The survey was from the Pew Forum on Religion and Public Life. They say, "The ... survey covered a wide range of topics, including the beliefs and practices of major religious traditions as well as the role of religion in American history and public life." The consitutional questions addressed people's knowledge the First Amendment of the U.S. Constitution, which is about the relationship between government and religion, among other things:

"Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances."

The questions about teaching about religion in public school concerned peoples' understanding of how the First Amendment is interpreted/applied.

(Amos, I'm working on your comment.)
