Question

The constant warfare between the independent Sumerian kingdoms _______.

A. Weakened them all.
B. Strengthened them all.
C. Created permanent alliances.
D. Resulted in the spread of disease.

Answer 1

The person above me is right, it is A

Answer 2

My best guess is A

Step-by-step explanation:

It's kind of the most reasonable answer. Obviously it wouldn't make them stronger, because they're losing men not getting more, alliances didn't really exist since all the city - states were separate, and diseases would not be spread through war.

I'm very sorry if I'm wrong!
