If W, X, Y, and Z are all positive numbers, is the value of W - X greater than the value of Y - Z?

(1) W and X are each greater in value than either Y or Z.

(2) W + Z = X + Y.

1) W > Y or Z; X > Y or Z (what about the relation between Y and Z)
-- Not sufficient

2) W-X = Y-Z
-- Sufficient (W-X is not greater than Y-Z but equal)

We understand you answer B, it's better if you declare it too from your very end. Thanks
