(B) Statement 2 alone should be sufficient.

From question p >= -5

From Statement 1: p ≤ -4 .so p= -4, -5. Insufficient

From statement 2: p < -4 and p > 4. so p =-5 and p > 4. InSufficient.

Combining 1 and 2: p= -5.

IMO C.

B for me. From question stem, we get p > = -5. From B we get p < -4. Hence p must be -5

From the question stem we get p >= -5

statement 1: P<= -4 , so p can be either -4 or - 5 => insufficient

statement 2 p<-4 or p>4, so p can be either -5 or any integer greater than 4 (4 is excluded ) - insufficient.

If we combine the statements we get that p is -4 or -5 (statement 1) and p less (but not equal) to 4. So the correct answer, I assume, should b C -> p can be only -5 if we combine the 2 statements together

So -> C

B is sufficient. p cannot be greater than 4 as question stem states - If p^3 >=-125...

Sorry but can you explain why p cannot be greater than 4?

from the question stem: p >= -5
and 4 >= -5 is true

It has to be C.

(1) 3p + 16 ≤ 4
(2) p^2 > 16


Good luck ! :D
p > -5

(1) p < -4, x could be -5 or -4
(2)-4 > p or p > 4. I don't get either why everyone automatically excludes p>4. It seems to me that p>4 is also a solution set to p>-5

(-4)^3 = -64 which is bigger than -125...

I agree on C.
