Read the excerpt from The Time Traveler’s Guide to Elizabethan England.

Rich landowners do not normally sell their grain immediately after the harvest is in, when prices are low; instead they store it until the numerous small-scale producers have sold all theirs and prices go up again. Pig farmers keep their flitches of bacon back in storage until they can get a better price for them later in the winter. Such tactics are made even more profitable by the unhappy fact that harvests can fail, causing local—and sometimes national—food shortages.

What inference can be made about both rich landowners and pig farmers, based on this excerpt?

A. They often ran out of food supplies before the end of winter came.
B. They were the only food suppliers for Elizabethan England all year long.
C. They cared more about making a profit than charging fair prices.
D. They made little profit from the food they supplied to their communities.
