Exactly six photographers are available�Frost, Gonzalez, Heideck, Knutson, Lai, and Mays�but not all have to be assigned. No photographer can be assigned to both ceremonies. The following constraints apply:
Frost must be assigned together with Heideck to one of the graduation ceremonies.
If Lai and Mays are both assigned, it must be to different ceremonies.
If Gonzalez is assigned to the Silva University ceremony, then Lai must be assigned to the Thorne University ceremony.
If Knutson is not assigned to the Thorne University ceremony, then both Heideck and Mays must be assigned to it.
Which one of the following, if substituted for the constraint that if Knutson is not assigned to the Thorne University ceremony, then both Heideck and Mays must be assigned to it, would have the same effect in determining the assignment of photographers to the graduation ceremonies?
If Knutson is assigned to the Silva University ceremony, then Heideck and Mays cannot both be assigned to that ceremony.
If Knutson is assigned to the Silva University ceremony, then Lai must also be assigned to that ceremony.
Unless Knutson is assigned to the Thorne University ceremony, both Frost and Mays must be assigned to that ceremony.
Unless Knutson is assigned to the Thorne University ceremony, Heideck cannot be assigned to the same ceremony as Lai.
Unless either Heideck or Mays is assigned to the Thorne University ceremony, Knutson must be assigned to that ceremony.
