In an effort to save energy and, thus, money,
many people keep their electric freezers halfempty
at all times, using them to store
prefrozen foods bought at a store and nothing
else. Yet freezers that are half-empty usually
consume more energy than they would if they
were kept fully stocked.

Which of the following, if true, contributes
most to an explanation for the apparent
discrepancy described above?

A)A person who normally maintains a halfempty
freezer would save a considerable
amount of money by using a freezer that
is half as large.
B)An electric freezer can operate efficiently
only if chilled air is free to circulate
within the freezing compartment.
C)A given volume of air in a freezer requires
much more energy to be maintained at a
temperature below freezing than does
an identical volume of frozen food.
D) The door of a full freezer is likely to be
opened more often, and for a longer
period of time, than is the door of a halfempty
freezer.
E)On average, it takes less energy to keep
food frozen than it does to get it from
room temperature to a frozen state.
