Calendars were developed for many reasons. Which of the following did not prompt the development of a calendar?
a. Farmers needed to know when to plant their crops.
b. People needed to be able to predict the annual floods.
c. Emperors needed a way to control their subjects.
d. Priests wanted to keep track of special days.
"c. Emperors needed a way to control their subjects" was not generally a way that calendars developed, since many despotic rulers actually wanted their subjects to be less informed, not more.
