Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the best answer to each of the questions from 36 to 42.

In the distance, an enormous, menacing-looking tornado can be seen. Luckily, the area has been evacuated and there is no one to be seen. Then, out of the blue, a few kilometres away a van appears and races down the road straight towards the tornado. Both in their twenties, Joe Hammond and his wife Emma are heading for it. Their purpose is to monitor various characteristics of a tornado, such as its speed, direction, and temperature. The storm chasers are planning to plant themselves directly in the path of the tornado to amass as much information as they can.

Joe and Emma are dedicated storm chasers. They began to chase storms as university students, and in recent years they have been travelling vast distances around the USA in their efforts to locate tornadoes. Bizarre as it may sound, they are not the only people to do it. During the tornado season, hundreds of people cross Tornado Alley, an area between South Dakota and Texas. Their vehicles are almost unrecognisable, as they are concealed underneath an assortment of electronic equipment and contain all manner of communication devices.

When asked why people are so fascinated by tornadoes, Joe said some tornado chasers relish the challenge, while others might just love the exhilaration of being in a treacherous situation. Some experienced chasers have even turned their hobby into a business and set up travel agencies offering tourists trips which guarantee a ringside view of the twisters. It seems, however, that people like Joe and Emma also make a pivotal contribution to the study of tornadoes.

The fact is, although there are about a thousand tornadoes in the USA each year, meteorologists still do not fully comprehend why they happen. This is partly because the research done by radars in laboratories is not as efficacious as mobile equipment deployed directly at the scene. Thus, some research meteorologists even go storm chasing themselves. It seems that the thrill, combined with a desire to understand nature, is the reason why people like Joe and Emma chase tornadoes.
