Discovery of streets arranged in a grid-like
pattern and a system of pipes for moving water in
Harappa and Mohenjo-Daro suggest that these
ancient river valley cities in South Asia had
(1) organized governments
(2) subsistence-based economies
(3) polytheistic beliefs
(4) rigid social classes
This discovery suggests that these ancient river valley cities in South Asia had "(1) organized governments," since the construction of such things often needs central control and an organized planning structure.
