(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.
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.
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
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.

B is sufficient. p cannot be greater than 4 as question stem states - If p^3 >=-125...bullzeye wrote:From the question stem we get p >= -5

Sorry but can you explain why p cannot be greater than 4?
from the question stem: p >= -5
and 4 >= -5 is true
from the question stem: p >= -5
and 4 >= -5 is true

It has to be C.

Good luck !
(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...crackgmat007 wrote:B is sufficient. p cannot be greater than 4 as question stem states - If p^3 >=-125...bullzeye wrote:From the question stem we get p >= -5

I agree on C.
