Why did farmers need to develop a system to control their water supply?

just like a paragraph about it : )

Farmers needed to control the water supply because too much water or too little water would kill the crops (too much would flood the fields and too little would lead to a drought)

the correct answer is batering

would be the one having to do with paine talking about how the colonies are so "close" to independence anyway, since he viewed that only rational next step at this point being revolution.
