premise: A government needs to assign new ambassadors to Venezuela, Yemen, and Zambia. The candidates for these ambassadorships are Jaramillo, Kayne, Landon, Novetzke, and Ong. One ambassador will be assigned to each country, and no ambassador will be assigned to more than one country. The assignment of the ambassadors must meet the following constraints: Either Kayne or Novetzke, but not both, is assigned to one of the ambassadorships. If Jaramillo is assigned to one of the ambassadorships, then so is Kayne. If Ong is assigned as ambassador to Venezuela, Kayne is not assigned as ambassador to Yemen. If Landon is assigned to an ambassadorship, it is to Zambia. Which one of the following CANNOT be true?
hypothesis: Novetzke is assigned as ambassador to Zambia.
