premise: The members of two committees, a planting committee and a trails committee, are to be selected from among seven volunteers—F, G, H, J, K, L, and M. The following conditions govern the composition of the committees: Each committee must have at least three members. F cannot be on the same committee as K. If K is on a committee, J must also be on that committee. M must be on at least one of the committees. The two committees must have at least one member in common. If K is on both committees and L is also on both committees and if the planting committee has exactly three members, then which one of the following must be true?
hypothesis: M is on the trails committee.
