Is P > |Q|
a. P^2 > Q^3
If P = 1 and Q = -3
P^2 > Q^3 (1 > -27) and P < |Q|

If P = 4 and Q = -3
P^2 > Q^3 (16 > -27) and P > |Q|.
We get two different answers(Yes and NO). Hence Insufficient.
b. P > Q
If P = 1 and Q = -3
P > Q (1 > -3) and P < |Q|

If P = 4 and Q = -3
P > Q (4 > -3) and P > |Q|
We get two different answers(Yes and NO). Hence Insufficient.
Using statements 1 and 2
If P = 1 and Q = -3
P > Q (1 > -3),P^2 > Q^3 (1 > -27) and P < |Q|

If P = 4 and Q = -3
P > Q (4 > -3),P^2 > Q^3 (16 > -27) and P > |Q|

We get two different answers(Yes and NO). Hence Insufficient. Answer E

Thanks -- when p is 4 & q is -3 => absolute of q > p, isnt it?
