VIII. Read the following passage then choose the best answer to the questions below.

Most people think of deserts as dry, flat areas with little vegetation and little or no rainfall, but this is

hardly true. Many deserts have varied geographical formations ranging from soft, rolling hills to stark,

jagged cliffs, and most deserts have a permanent source of water. Although deserts do not receive a high

amount of rainfall – to be classified as a desert, an area must get less than twenty-five centimeters of rainfall

per year – there are many plants that thrive on only small amounts of water, and deserts are often full of

such plant life.

Desert plants have a variety of mechanisms for obtaining the water needed for survival. Some plants,

such as cactus, are able to store large amounts of water to last until the next rainfall. Other plants, such as

the mesquite, have extraordinarily deep root systems that allow them to obtain water from far below the

desert’s arid surface.
