More than two hundred years ago, the term “environmental pollution” was quite strange to people. They lived healthy, drank pure water, and breathed fresh air. Nowadays, the situation is quite different. People all over the world are worried about things that are happening to the environment. Actually it is man that is destroying the surroundings with many kinds of wastes. Everybody knows that motorbikes and cars emit dangerous gases that cause poisonous air and cancer, but no one wants to travel on foot or by bicycle.

Read the following passage and mark the teller A, B, C, or D on your answer sheet to indicate the correct answer to each of the following questions.

People sometimes call Mercury the morning star or evening star. Mercury is half the size of the earth. Because it is much lighter, it has much less gravity. If you can visit Mercury in a spaceship, you will find it a strange world. Its low gravity makes you feel very light. If your weight on earth is 100 pounds, your weight on Mercury is only 27 pounds. Looking at the sun from Mercury, you can see that it’s much more brilliant than it is seen from the earth. And the yellow centre of the sun appears three times bigger from Mercury. On the lighted side, Mercury’s temperature is about 300 degrees centigrade. But the dark side is extremely cold, 150 degrees below zero so Mercury is probably the coldest as well as the hottest of the planets.
