VII/ Read the passage and choose the best answer
The word ‘desert’ conjures up an image of a hot, dry and arid landscape. There are many different kinds of deserts. In general,
a place where the water evaporation rate exceeds the amount of annual rainfall is usually classified as being a desert. Therefore,

deserts are not necessarily subject to hot temperatures. ‘Hot’ deserts experience high temperatures during the day all year round
while ‘cold’ deserts have relatively hot summers and extremely cold winters.
Deserts cover about one-fifth of the earth’s land area. Desert plants like cacti are not abundant, neither is animal life. Animals
that live in the desert have adaptations to cope with the lack of water, the sudden changes of temperatures and the shortage of food.
To avoid daytime heat, many of them are nocturnal; they burrow beneath the surface and emerge at night to eat. Many desert
animals do not have to drink at all because they get all the water they need from their food. Most of them are small.
46. A desert is ___________.
A. either hot or cold B. neither hot nor cold
C. a place with extreme temperatures. D. a temperature zone
