Using the number line below, choose all the statements that are correct if p < 0 and q < 0, where p and q are rational numbers.

-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10

The inequality p - q < 0 is possible because -5 - (-4) = -1.
The inequality p + q > 0 is possible because -5 + (-5) = 10.
The inequality p + q < 0 is possible because -5 + (-5) = 0.
The inequality p - q > 0 is possible because -4 - (-5) = 1.
The inequality p - q < 0 is possible because -5 - (-5) = -10.
The inequality p + q < 0 is possible because -5 + (-5) = -10.
