If L is to the right of M, and N is to the left of L, we can deduce that H is sitting opposite M.

Given that M is between N and O, and P is opposite M, R must be next to O in the arrangement.

With M between N and O, and P opposite M, N will be to the left of P.

The arrangement is Q-P-R. Therefore, P is sitting next to R.

With R between S and T, and U opposite R, T will be to the right of U.

Given that T is next to U and V is opposite T, W must be next to V.

With T to the left of U, and V opposite T, Y must be to the right of U in the arrangement.

Since X is between Y and Z, and W is opposite Y, the only person who can be next to W is Z.

Since X is between Y and Z, Z's left must be X in the circular arrangement.

Since Z is opposite X, and X is next to Y, Y must be next to Z.

Since Z is opposite Y and X is next to Y, the only person who can sit next to Z is B.

Since P is between Q and R, the arrangement can be visualized as Q-P-R. If S is opposite P, then T and U must be next to S. Thus, R is next to S.

If P is third to the left of Q, then counting clockwise, R is immediately right of P. Therefore, S must be opposite Q.

Starting from Q, if P is third to the left, we can determine R's position. R's position can then help us find the person directly opposite R, which is Q.

By placing Q at a position, we can determine P's position. R's position can then be calculated, leading to the conclusion that T is opposite Q.

Team C has the highest score since A < C.

The only arrangement that satisfies the condition of Z being between X and Y is X, Z, Y.

Since A is at one end and B is to the right of A, it is clear that A is to the left of B.

Since S is to the left of U and T is to the right of U, S must be to the left of T.

All statements are true based on the seating arrangement.

Since A is in chair 1, B in chair 2, and C in chair 3, B is indeed sitting in the middle.

Since Book C is to the right of Book D, it must be true that Book D is to the left of Book C.

Since A is to the left of B and C is to the right of D, we can infer that A must be to the left of C, but we cannot determine the exact positions of D and B relative to each other.

Without knowing the specific positions of Books C and D relative to A and B, we can only infer that A is to the left of C, but not the other options.

The arrangement H, I, J, K, L, M satisfies the condition of H being to the left of I and J being to the right of I.

Since P is to the left of Q and R is to the right of S, it is possible for R to be to the right of Q depending on the arrangement of the other individuals.

Since P is to the left of Q and R is to the right of Q, Q must be in the middle.

Since J is between K and L, L is sitting next to K.

Given J is between K and L, and M is opposite K, we can conclude that P is next to L.

If J is three places away from K, there are two people sitting between J and K.
