premise: A publisher is planning to publish six cookbooks—K, L, M, N, O, and P—over the course of the next year. Each cookbook will be published in one of two seasons—fall or spring—subject to the following conditions: M and P cannot be published in the same season as each other. K and N must be published in the same season as each other. If K is published in the fall, O must also be published in the fall. If M is published in the fall, N must be published in the spring Which one of the following, if substituted for the condition that if M is published in the fall, N must be published in the spring, would have the same effect in determining the schedule for the publication of the cookbooks?
hypothesis: If N is published in the spring, M must also be published in the spring.
