*Question*
I'm taking a test and have to guess the right answer to the question after the article. Article: We can't deny that trees are useful to man in three very important ways: they provide him with wood and other products, they give him shade, and they help to prevent drought and floods. Unfortunately, in many parts of the world man has not realized that the third of these services is the most important. In his eagerness to draw quick profit from the trees, he has cut them down in large numbers, only to find that without them he has lost the best friends he had. Two thousand years ago a rich and powerful country cut down its trees to build warships, with which to gain itself an empire. It gained the empire but, without its trees, its soil became hard and poor. When the empire fell to pieces, the country found itself faced by floods and starvation. Even though a government realizes the importance of a plentiful supply of trees, it is difficult for it to persuade the villager to see this. The villager wants wood to cook his food, and he can earn money by making charcoal or selling wood to the townsman. He is usually too lazy or too careless to plant and look after trees. So unless the government has a good system of control, or can educate the people, the forests will slowly disappear. This does not only mean that the villagers' sons and grandsons have fewer trees. The results are even more serious. For where there are trees ,their roots break the soil up, allowing the rain to sink in and also bind the soil, thus preventing it being washed away easily, but where there are no trees, the soil becomes hard and poor. The rain falls on hard ground and flows away on the surface, causing floods and carrying away the rich topsoil, in which crops grow so well. When all the topsoil is gone, nothing remains but worthless desert. Question: Sooner or later the forests will disappear _ Options: A: unless people are taught the importance of planting trees B: unless people stop cutting down their trees C: unless a county has a plenty supply of trees D: unless the government punishes those who cut trees instead of planting trees

*Question*
I'm taking a test and have to guess the right answer to the question after the article. Article: The smell of fresh air is becoming something of a distant memory, thanks to our increasing use of fragrance . From air fresheners to scented candles, we live in a world of scent. Recent figures show seven in ten people use air fresheners or scented candles to keep our homes smelling sweet. Yet recent records suggest that perfumed products could affect our health, causing problems including allergies , headaches and asthma . One leading expert believes nearly a third of people suffer health effects from being exposed to scents. A major problem is so-called "contact" allergy--where perfumes and scented products cause eczema when they come into contact with the skin. About one in 20 is thought to be affected by fragrance allergy. "Often it may not be immediately obvious that you have developed a fragrance allergy," says Dr. Baron. "You don't react immediately. Gradually, as you are exposed more and more, the body increases its reaction, until it becomes noticeable to you." People with pre-existing eczema are particularly vulnerable . "The eczema worsens in areas in contact with perfumes," says Dr. Baron. "But even those without allergies can be at risk of fragrance allergy." You can become suddenly allergic to perfumes and personal care products that you have been using for years. "Even if you know which fragrance causes a problem, it can be difficult to avoid, as most personal care products -soap, shampoo, sun cream and washing powder--contain fragrances," says Dr. Baron. And strong scents can also cause headaches. Fragrances activate the nose's nerve cells, stimulating the nerve system associated with head pain. To minimize risk, sufferers are advised to minimize the contact. "Fragrance suggest cleanliness - yet people are smelling a potentially dangerous chemical mixture," says Anne Steinemann, professor of the University of Washington. "We often use them to mask one problem - as with air fresheners - but create a greater one - adding poisonous chemicals to the air." Question: What is the text mainly about? Options: A: The world trend of using fragrance. B: The benefits of using non-fragranced products. C: The health problems caused by fragrance D: The ways of removing allergy.
