Re: w>x>0>y>z [#permalink]

I agree

If we take the inequality by chunk we do know that

\(w>x>0\)

and they are positive

\(0>y>z\)

And they are negative

However we do know the magnitude of the numbers

Could be anything

For example

w=10 nd x=3

y=-3 and z=-4

w+y=7

x+z=-1

The answer is A

BUT if we have

w=10 and y -3 we have w+y=7

and x=9 and z=-2 and x+z=7

And the answer is C

I agree that it is D the OA
