Marla was rummaging through some boxes in the attic and found a stack of letters her great-grandfather wrote when he was stationed in North Africa during World War II. One of the letters included these lines: “Last week we almost ran out of fuel. Most of our training was cancelled. This week we received double the usual amounts. I guess it’s feast or famine around here.”

Using the context of the letter as a clue, what does the phrase feast or famine mean?

A
It’s difficult to complete training without enough fuel.

B
You should maintain extra supplies around at all times.

C
Things sometimes go from one extreme to another.

D
The soldiers were starving because there wasn’t enough food.
