Read the following passage and choose the best option to complete the
blank or answer the question.
Since water is the basis of life, composing the greatest part of the tissues of
all living things, the crucial problem of desert animals is to survive in a
world where sources of flowing water is rare. And since
man's inexorable necessity is to absorb large quantities of water at frequent
intervals, he can scarcely comprehend that many creatures of the desert pass
their entire lives without a single drop.
Uncompromising as it is, the desert has not eliminated life but only those
forms unable to withstand its desiccating effects. Nomoist-skinned, water-
loving animals can exist there. Few large animals are found: the giants of the
North American desert are deer, the coyote, and the bobcat. Since desert
country is open, it holds more swift-footed, running, and leaping creatures
than the tangled forest. Its population is largely nocturnal, silent, filled with
reticence, and ruled by stealth. Yet they are not emaciated. Having adapted
to their austere environment, they are as healthy as animals anywhere in the
world.
The secret of their adjustment lies in a combination of behavior and
physiology. None could survive, if, like mad dogs and Englishmen, they
went out in the midday sun, many would die in a matter of minutes. So most
of them pass the burning hours asleep in cool, humid burrows underneath
the ground, emerging to hunt only by night. The surface of the sun-baked
desert averages around 150 degrees, but 18 inches down the temperature is
only 60 degrees.
