22-A
23-B

22- anything greater than 3 will yield a positive answer according to 1 while 2 is inconclusive

23- in 1, a or b could be negative or positive and different. 2 makes sure that a and b are equal and also bear the same sign

22-1. k can be < 3, say, when 1 < k < 2, (k-1)(k-2)(k-3) > 0.

E is the answer

E and B is the OA. Paul Halle explainations makes sense since it doesn't say anywhere that k has to be integer.

Neither of the statements is sufficient:

k = 1.5 is the example.

2 alone is sufficient:

a^3 = b^3 => for real numbers a and b a = b. => ab = a^2 = b^2.
