IMO A -
From the question stem, we can figure out that if 'y' has to be a fraction,then 'x' has to be a fraction too..
Stmt 1 - x^2 is a fraction.
This implies 'x' has to be a fraction.
Hence 'y' will also be a fraction
Sufficient
Stmt 2 - X>Y
Insufficient.

IMO - D
statement 2 - we can conclude that x != y because x > y
therefore x and not equal to 1. Now there is only one possibility 0 < x < 1.
