As I read that assignment it appears that there are a list of statements including one that says "There is a God" and another that says "The ugliest sea creature is the manatee." The directions then indicate the students are to indicate whether the statement is either a factual claim (FC), Commonplace Assertion (CA), or Opinion (O). Based on those directions I'm not entirely sure how we get the idea that these students were made to literally deny the existence of God.
