A green house is a building made of glass which is used for keeping warm when the outside temperature is low. In a similar way there are several gases in the atmosphere (mixture of gases that surround the earth) which trap the heat produced by the sun and prevent it from escaping. These gases are known as "greenhouse gases". And the way in which they trap heat in the atmosphere is called the "greenhouse effect". This is not simply air pollution. Most of the main greenhouse gases exist naturally in small amounts in our atmosphere, and without them the earth would be 30 degrees colder and human life would not exist. In other words, the greenhouse effect is a natural course which is to some degree helpful to us. The problem is that in the last century and a half, we have been putting too many of these gases into the earth's atmosphere by burning large quantities of coal and oil and by cutting down forest. The rapid increase in greenhouse gases is making the world warmer. The world's temperature has already gone up by half a degree this century, and the sea level has risen by 10 centimetres. If the amount of carbon dioxide in the atmosphere doubles, there will probably be a rise in the earth's temperature of between I and 4degC;. This may seem a small increase, but it would be enough to cause major changes in geography and agriculture. Large areas of the world would be flooded, and some areas would become dry and unable to produce crops. It is important, too, to consider that there may be a delay of about 30 years in the greenhouse effect. This means that we are probably experiencing only now the effect of the gases put into the atmosphere before the 1960s. Since then, our use of these gases has greatly increased. Suppose the earth's temperature rose by 3 degrees, _ . A) great harm will be done to mankind B) the sea level would go up by 10 centimeters C) all the land in the world would be flooded D) crops would be unable to grow on the earth

(Question)
One of the most difficult questions to answer is how much a job is worth. We naturally expect that a doctor's salary will be higher than a bus conductor's wages. But the question becomes much more difficult to answer when we compare a miner with an engineer, or an unskilled man working on an oil-rig with a teacher in a secondary school. What the doctor, the engineer and the teacher have in common is that they have devoted several years to studying in order to obtain the necessary qualifications for their professions. We feel instinctively that these skills and these years should be rewarded. At the same time we recognize that the work of the miner and the oil-rig laborer is both hard and dangerous, and that they must be highly paid for the risks they take. Another aspect we must take into consideration is how socially useful a man's work is. Most people would agree that looking after the sick or teaching children is more important than, say, selling second-hand cars. Yet it is almost certain that the used-car salesman earns more than the nurse and the schoolteacher. Indeed, this whole question of just rewards can be turned on its head. You can argue that a man who does a job which brings him personal satisfaction is already receiving part of his reward in the form of a so-called "psychic wage", and that it is the man with the boring, repetitive job who needs more money to make up for the soul-destroying repetitiveness of his work. It is significant that the jobs like nursing and teaching continue to be poorly paid, while others, such as those in the world of sport or entertainment, carry financial rewards out of all proportion to their social worth. Although the amount of money that people earn is largely determined by market forces, this should not prevent us from seeking some way to decide what is the right pay for the job. A starting point would be to try to decide the ratio which ought to exist between the highest and the lowest paid. The picture is made more complicated by two factors: firstly by the... Why do people naturally expect that doctors should be well-paid? A) Their work requires greater intelligence. B) They are under constant pressure at work. C) They work harder than most other people. D) They have studied for years to get qualified.
