Hi,
I am reviewing the questions from the Official Practice Test 1. Can anybody help me understand question 3? (data sufficiency)
Is |x|>|y|?
(1) \(x^2>y^2\)
(2) x>y
Thank you!

I'm unsure why statement 1 is insufficient
Absolute value determines how far a number is from zero on the number line. Squaring ensures both numbers are on the same side of zero (the positive side). This shouldn't be affected by 0<a<1, fractions, negatives etc

because x and y, depending whether they lie between (0, 1) or (1 , inf) change the answer.
The statement is not sufficient.
