C. READING
I. Read the passage and choose the best answer.
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 veried 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 yeat –
there are many plants that thrive on only small amount of water, and deserts are often full of such plant life.
Desert plants have a veriety of mechanism for obtaining the water needed for survival. Some plants,
such as cactus, are able to store large amount of water in their leaves oe stems; after aa rainfall these plants
absorb a large supply of water to last until the next rainfall. Other plants, such as the mesquite, have
extraodinarily deep root systems that allow them to obtain water from far below the desert’s surface.
