How many staff members are senators allowed to employ

That depends. I read one time how every year they employ around 115 to 190 staff members. I hope this helps you! :)

To solve their problems, mesopotamians used irrigation, a way of supplying water to an area of land. to irrigate their land, they dug out large storafe basins to hold water supplies these ditches brought water to the feilds. to protect their feilds from flooding, farmers built up the banks of the tigris and euphrates.hope ths !
