From statement I, X is two boxes above T. Y is one box below T. Only three boxes are between W and Y. W is below Y. U is one box above W. We get: From statement I alone, we get Y is kept three boxes above U. From statement II, R is the third box from the bottom. Only three boxes are between R and S. T is one box above Y, which is one box above V. U is below V. We get:
