Simple quantitative comparison
OK, I was going thru a very common book for QC, which I find on multiple websites:
"501 Quantitative Comparison Questions"
One such website is
If you look at question 18 on page 3, it compares
( p squared ) with - (p squared)
The and explanation that book gives is as follows:
A : Any number squared is positive. Therefore, p squared is positive and - p squared is negative. A positive number is always greater than a negative number. Quantity A is greater
I see that they overlooked the fact that p could be 0 in which case both sides will be equal. So it should actually be D (cannot be determined conclusively).
Just wondering, how could they miss this important fact or am I missing something (?)

yes, the answer provider forgot to include zero as a possible value for p ... given solutions are not always correct. It happens.
