Read the passage carefully and choose the correct answer.
A desert is a hostile, potentially deadly environment for unprepared humans. In hot deserts, high temperatures cause rapid loss of water due to sweating, and the absence of water sources with which to replenish it can result in dehydration and death within a few days. In addition, unprotected humans are also at risk from heatstroke.
Humans may also have to adapt to sandstorms in some deserts, not just in their adverse effects on respiratory systems and eyes, but also in their potentially harmful effects on equipment such as filters, vehicles and communication equipment. Sandstorms can last for hours, sometimes even days.
Despite this, some cultures have made hot deserts 'their home for thousands of years, including the Bedouin, Tuareg tribe, and Pueblo people. Modern technology, including advanced irrigation systems, desalinization and air conditioning, has made deserts much more hospitable, In the United States and Israel for example, desert farming has found extensive use.
In cold deserts, hypothermia and frostbite are the chief hazards, as well as dehydration in the absence of a source of heat to melt ice for drinking. Falling through pack-ice or surface ice layers into freezing water is a particular danger requiring emergency action to prevent rapid hypothermia. Starvation is also a hazard; in low temperatures the body requires much more food energy to maintain body heat and to move. As with hot deserts, some people such as the Inuit have adapted to the harsh conditions of cold deserts.

Read the passage carefully and choose the correct answer.
Approximately one-third of the Earth's land surface is desert, arid land with meager rainfall that supports only sparse vegetation and a limited population of people and animals. Deserts have been portrayed as fascinating environments of adventure and exploration. These arid regions are called deserts because they are dry. They may be hot. They may be cold. They may be regions of sand or vast areas of rocks with occasional plants.
Deserts are natural laboratories in which to study the interactions of wind and sometimes water on the arid surfaces of planets. They contain valuable mineral deposits that were formed in the arid environment or that were exposed by erosion. Because deserts are dry, they are ideal places for human artifacts and fossils to be preserved. Deserts are also fragile environments. The misuse of these lands is a serious and growing problem in parts of our world.
There are many animals in the desert. Some are very large, like the kangaroo or the gazelle. Both are big and have to travel long distances for water at a spring, or an oasis. Another fairly large animal is the addax. The addax is a desert antelope. They live in the Sahara Desert. All addaxes are herbivores. There are less than 200 of them left because of hunting and tourists. Some animals crawl along. Examples of these are snakes and lizards. Snakes rarely drink water; they get their moisture from other prey that they eat. So do others, like the kangaroo rat. Lizards are commonly found in the desert. They stay out of the sun and move as little as possible. There are also other animals in the desert. The fennec lives in northern Africa in the Sahara Desert. They are a relative of the fox. They eat mice, small birds, lizards, and insects. When necessary, they will eat fruit. One more desert animal is the jerboa. The jerboa is a small, long distance jumper that lives in the desert. They are free drinking animals and they eat plants, seeds, and bugs.

a. are rare in the world 	b. are more arid more populous
c. are all hot all the time 	d. may be both hot and cold
The word They refers to ________.
a. deserts 	b. natural laboratories 	c. planets d. mineral deposits
Which is not true about deserts?
a. arid 	b. hot 	c. humid 	d. dry
According to the second paragraph, ________.
a. we should use desert land properly to avoid serious problems
b. we can exploit as much fossil as possible in deserts
c. there are no erosion in deserts
d. deserts are ideal places for growing land
The last paragraph expresses that ________.
a. none of animals can survive in deserts
b. hunting and tourists cause the decreasing of addaxes in the Sahara Desert.
c. snakes in deserts need more water than any other species
d. addaxes are the most populous species in deserts

Advanced skills or devices are required to navigate through such landscapes and (46) _____ travelers may die when supplies run (47) ______ after becoming lost. In addition, sandstorms or blizzards may cause disorientation in severely-reduced visibility.
