premise: It was sent out with no name on it, but it is under the heading "Standing Committee on Privileges, Standing Rules and Orders," which is scheduled to meet today, November 23, at 4:30 p.m. The agenda has five items on it, four of which have nothing to do with a question of privilege.
hypothesis: Standing Committee on Privileges, Standing Rules and Orders does not have anything to do with the letter.
reason: Standing Committee on Privileges, Standing Rules and Orders was the only thing written on the letter or envelope so the answer is incorrect.
