Hello @ame1,

Let's go through the rules. What else has to happen if N is published in the fall?

1. K must also be in the fall.

F: N K

2. If K is published in the fall, then so is O.

F: N K O

This demonstrates why O cannot be published in the spring.

@ravi how can L go in spring?
If N then K
if K then O
if N(fall) then M(spring)
if M(spring) then P(fall)
where is room for L to go in fall?
