of office. Your duties are to distribute food, direct farming, and buy and sell land
as needed to support your people. Watch out for rat infestations and the resultant
plague! Grain is the general currency, measured in bushels. The following will help
you in your decisions:
(a) Each person needs at least 20 bushels of grain per year to survive.
(b) Each person can farm at most 10 acres of land.
(c) It takes 2 bushels of grain to farm an acre of land.
(d) The market price for land fluctuates yearly.
Rule wisely and you will be showered with appreciation at the end of your term. Rule
poorly and you will be kicked out of office!'''
