premise: Exactly three films—Gambhir, Haseen, and Lehenga—are shown during a film club's festival held on Thursday, Friday, and Saturday. Each film is shown at least once during the festival but never more than once on a given day. On each day at least one film is shown. Films are shown one at a time. The following conditions apply: On Thursday Haseen is shown, and no film is shown after it on that day. On Friday either Gambhir or Lehenga, but not both, is shown, and no film is shown after it on that day. On Saturday either Gambhir or Haseen, but not both, is shown, and no film is shown after it on that day. If Lehenga is shown exactly three times, Haseen is shown exactly twice, and Gambhir is shown exactly once, then which one of the following is a complete and accurate list of the films that could be the first film shown on Thursday?
hypothesis: Gambhir, Lehenga
