Before we look at the question, let's make sure our game setup is good.
We have 4 chess games and 6 players, so we know there will be some repeats. The pieces are L, N, O, P, S, and T.
_ _ _ _ _ _ _ _
We know T isn't in 1 or 3, so T has to be in 2 or 4. The two slots in both 2 and 4 are interchangeable because the slots represent the players in the game.
L plays in 4
_ _ _ L _ _ _ _
We know that N is only in one game and it isn't with P
NP not together and N doesn't repeat
S plays in 2 games, 1 just before and just after O plays
SOS
We can split the game into two boards, putting the SOS next to L and then another where SOS overlaps with L
SOSL _ _ _ _
_ _ _ L _ S O S
In the second board, T must go in 2 because 4 is totally occupied
_ T _ L _ S O S
We know N and P can't be together, so they have to split 1 and 3
N T P L _S O S
or
P T N L _ S O S
The other position has to be L since it's the only player available to fill in the spot in 1
P T N L L S O S
Since we know N and O don't repeat, we know that either L, P, or T must repeat so that we fill out all 8 slots.
In looking at the top board, it's still very open, so we just need to keep in mind the rules for it.
SOSL _ _ _ _
The question tells us that T is in 4. This means we're looking at the first game board since T is in 2 in our second one.
SOSL _ _ _T
With (A), N could definitely be in 2. We could put P in 3 and L in 1.
(B) is wrong because there's only 1 O allowed, and it's already occupying 2.
(C) is wrong because there are 2 S pieces on our board already and they're in 1 and 3.
(D) is wrong because T is with L, so N can't be with L
(E) is wrong because T is with L, so P can't be with L
SOSL _ _ _T
Hope this helps. Let us know if you have any more questions!
