Ls-->Nr + Nr-->Os = Ls-->Os (combination of rules 3 + 4)
Ls-->Pr + P--r>Os = Ls-->Or (combination of rules 3 + 5)

I've looked at it 4 times and can't figure out what I am missing. Does this mean Ls is not possible or am I messing up my conditionals? Help, please..?

you're def right. Ls isn't possible.

OK, cool. Thanks for the link. You would think if they are going do something like that they would atleast insert a "which of the following can never be placed in S" question so you atleast know you're missing something. They are just plain mean people.

haha i hear you. i agree that they are plain mean, but not for that reason.

they actually do ask about something really similar to Ls never happening, though.

they ask which two can't ever both be on R simultaneously - answer: N and P. Ls causes Nr and Pr, so there you go.
