k is an integer. k=?

1) k^2 < 16
here, k maybe a positive or negative integer. Insufficient

2) -60 < k^3 < -20
k can only be (-3) by trial and error method of placing negative integers in place of k in this equation. Sufficient.

K is negative as cube of number gives negative
Only value k=-3 qualifies for this case

I put E as an answer because I thought at -3.5 could also be an answer since -3.5^2 < 16 And -3.5^3 is also smaller than -20....

Why does K have to even be an integer ?
