premise: In a theater company, four two-day workshops—Lighting, Production, Rehearsals, and Staging—are conducted over the course of five days, Monday through Friday. The workshops are conducted in a manner consistent with the following constraints: The two days on which a given workshop is in session are consecutive. On each of the five days, at least one, but no more than two, of the workshops are in session. The workshops on Production and Rehearsals begin no earlier than the day immediately following the second day of the workshop on Lighting. If the workshop on production is the only workshop in session on Friday, which one of the following must be false?
hypothesis: The workshop on Lighting is in session on the same two days as is the workshop on Staging.
