Read the information carefully and answer the questions below.
A weekly television show routinely stars six actors, Jeevan, Karan, Lalit, Manish, Nishant, and Omkar. Since the show has been on the air for a long time, some of the actors are good friends and some do not get along at all. In an effort to keep peace, the director sees to it that friends work together and enemies do not. Also, as the actors have become more popular, some of them need time off to do other projects. To keep the schedule working, the director has a few things she must be aware of:
1. Jeevan will only work on episodes on which Manish is working.
2. Nishant will not work with Karan under any circumstances.
3.Manish can only work every other week, in order to be free to film a movie
4. At least three of the actors must appear in every weekly episode.
