Is 1/p > [r/(r^2 + 2)]?
(r^2 + 2)/p > r?
(r^2 - rp + 2)/p > 0?
[r(r-p) + 2]/p > 0?
This statement is true when r(r-p) + 2 and p have the same sign, ie they are both positive or both negative. But we'll see whether we can simplify this with information from the statements.
Statement 1) p=r, or (p-r)=0
[r(0) + 2]/p > 0?
2/r > 0? r > 0? Is r positive?
We still do not know the sign of r, so this statement is insufficient alone.
Statement 2) r > 0
We still have no information on p, so this statement is insufficient alone.
Combined) our modified question stem from statement 1: r > 0? is confirmed by statement 2.
Sufficient.
IMO C
