XI.Read the following passage, choose the best answer for each question followed.

Since the world has become industrialized, there has been an increase in the number of animal species that have either become extinct or have neared extinction. Bengal tiger, for instance, which once roamed the jungles in vast number, now only about 2,300 and by the year 2025, their population is estimated to be down to zero. What is alarming about the case of the Bengal tiger is that this extinction will have been caused almost entirely by poachers who according to some sources, are not interested in material gain but in personal gratification. This is an example of the callousness that is part of what is causing the problem of extinction. Animals like Bengal tigers as well as other endangered species are a valuable part of the world’s ecosystem. International laws protecting these animals must be enacted to ensure their survival and the survival of our planet.

Countries around the world have begun to deal with the problem in various ways. Some countries, in order to circumvent the problem, have allocated large amounts of land to animal reserves. They then charge admission to help defray the costs of maintaining the parks and they often must also depend on world organizations for support. With the money they get, they can invest in equipment, and patrols to protect the animals. Another solution that is an attempt to stem the tide of animal extinction is an international boycott of products made from endangered species. This seems fairly effective but it will not, by itself, prevent animals from being hunted and killed.

Two of the most dangerous storms which affect America are hurricanes and tornadoes. They are very much feared by anyone who may live in the path of their destruction.

Every year homes are destroyed by their fury and often lives are lost. Most people who live near the coast are forced to evacuate their homes and to move to safer areas until the storm passes. Floods are caused along the coasts by both the heavy rain and a storm tide that is considerably above normal water level. The high winds, coastal flooding and heavy rains associated with a hurricane cause enormous damage.

Hurricanes usually develop between July and October. Once they hit land they carry tremendous power with driving rain and wind.

Tornadoes are violent low - pressured storms. These storms occur most often during the summer months and are noticeable by their strong wind and lack of rain. The sky turns black as dust is sucked up into the air. Tornadoes are capable of lifting quite heavy objects from the ground. They can pick up trees and cars right into the air and even uplift heavier objects such as homes and railway cars.

Both hurricanes and tornadoes cause millions of dollars worth of damage to life and property every year. Today they can be predicted more easily than in the past, but they cannot be stopped or ignored.
