1) The only two prime numbers within that range are 53 and 59. X can be 54, 55, 56, 57, 58. X can have 5 values. Sufficient

2) W=1, Y=7, X could be 2, 3, 4, 5, 6--> 5 values
W=1.5, Y=7.5, X could be 2, 3, 4, 5, 6, 7 --> 6 values.
Insufficient.

Answer is A (though it's tricky! I almost jumped the gun and said D. Remember, we don't know if Y and W are integers!)
