What is the value of N?

In order the answer to be B it should be as follows:

(1) (N + 5)^3> 0 --> n+5>0 --> n>-5, not sufficient to determine single numerical value of n.

(2) (N - 5)^2≤ 0 --> as square of a number is always non-negative (zero or positive), then (n-5)^2 can not be less than zero thus it must equal to zero: n-5=0 --> n=5. Sufficient.

MichelleSavina please check the questions for typos when posting.
