Hi Roppo,

I'd be happy to jump in and help! So in this question, we are told that P is sixth. Because of rule 2, we can deduce that L must be seventh. And because of rule 4, we can deduce that M must come before P, thus ensuring the M - J - K chain must occur. That just leaves H and O. We know from rule 1 that H must come sometime after J, and the only thing we know about O is that it has to come sometime before P. But since P is already sixth, we know that O can go anywhere in slots 1 - 5.

A) Because O can go anywhere, it doesn't have to be true that J is released earlier than O. O can go before J no problem. For example: O M J H K P L

B) H has to come after J and before P, but there's nothing forcing K before H. H can go before K without issue. The example in (A) shows this.

C) CORRECT. Because M must come before J and J must come before H, it does in fact have to be true that M comes before H.

D) Again, O can go anywhere in slots 1-5, so M doesn't have to go before O. It can go after no problem. This example in (A) shows this.

E) Once again, O can go anywhere in slots 1-5, so O doesn't have to go before H. For example: M J H O K P L

Hope this helps!
