My reasoning

Here we do not know anything about sign of p, q, r and s

A
no info about q
Insuff

B
no info about p
Insuff

A+B
add both inequalities
p+q > 2(r+s)

now we can not assume that p+q is greater than r+s
bcoz the (r+s) can be negative also

let me try with an example

p+q = -1.5
r+s = -1

now
p+q > 2(r+s)
but
p+q < r+s

You will certainly not, just have enough confidence in yourself.

Good Luck!!!
