Write a multi-choice question for the following article: Article: In South America, the rich soil of the Amazon River basin in Brazil is known as "black gold". Scientists found that the secret of this rich soil was charcoal . Local people made it from animal bones and tree branches. They mixed the charcoal with the soil about 1.500 years ago. Now, scientists in the United States have done a modern demonstration. They say charcoal fertilization offers a revolutionary way to improve soil quality for hundreds or even thousands of years. Mingxin Guo and his team at Delavare State University heated tree leaves, corn stalks , small pieces of wood and poultry waste into "biochar" . They reported their findings at a recent meeting of the American Chemical Society in New Orleans. Biochar could be good news for farmers with poor soil and hungry populations to feed. Professor Guo says it could even help against global warming. Intensive farming and overuse of chemical fertilizer give out carbon dioxide into the atmosphere. Biochar does the opposite, he says. It traps carbon in the ground. The researchers planted winter wheat in containers of soil in a greenhouse -- some with biochar, some without. Professor Guo says the wheat grows much better in the pots with biochar. The soil was added two percent charcoal to. But he says even a one percent treatment will increase productivity. The results demonstrated that biochar can increase organic matter in soil. Loss of nutrients in soil is an increasing problem worldwide as farmers try to grow more food for growing populations. Next, the team will carry out a five-year study of biochar with spinach , green peppers and tomatoes. Mingxin Guo says he learns about the "black gold" in Brazil from a magazine story. He explains that it was discovered in the jungle, in the area where waters flow to the Amazon, in the 1960's. But it was not until recent years that scientists began to bring public attention to it.

Write a multi-choice question for the following article: Article: The past fifty years or so have seen the gradual disappearing of animals from this earth, fishes from the sea, trees and plants from the land. Many factors result in this on pleasant phenomenon . Among them, hunting is the main factor that endangers wild life. Some people kill wild life for sport. They take pleasure in collecting heads and hides. Yet others specialize in commercial hunting like killing whales. Apart from this, the rapidly growing human population threatens wild life on land, too. Towns expand and roads have to be built, so forests are burnt and trees are cut down. It seems that man needs every inch of land within his reach, so he moves on to the natural habitat of wild life. Tigers lions and leopards slowly die off without the food arm shelter that the forests provide. In addition, rapid urbanization means industrial expansion. Very often, poisonous chemicals, industrial wastes and oil are dumped into the rivers and seas. Fish and birds are threatened. Man depends greatly on animals for survival. He needs their flesh, hides and furs. Thus, man cannot, to without wild life; or he himself would die out. The public should be made aware that it would be better to shoot the animals with a camera than with a gun. In this way, they can preserve and help wild life to continue living rather than to remove all signs of it. Man must learn to farm the sea as he does the land. He should control the amount and the frequency of his catch. Man also needs to build reserves, and to pass laws to stop the killing of animals, especially those that are already rare. To keep the present animal kingdom, the least that man can do is to clean the seas and to prevent pollution.

Write a multi-choice question for the following article: Article: Compassion is a desire within us to help others. With effort, we can translate compassion into action. An experience last weekend showed me this is true. I work part-time in a supermarket across from a building for the elderly. These old people are our main customers, and it's not hard to lose patience over their slowness. But last Sunday, one aged gentleman appeared to teach me a valuable lesson. This untidy man walked up to my register with a box of biscuits. He said he was out of cash , had just moved into his room, and had nothing in his cupboards. He asked if we could let him have the food on trust. He promised to repay me the next day. Icouldn't help staring at him. I wondered what kind of person he had been ten or twenty years before, and what he would be like if luck had gone his way. I had a hurt in my heart for this kind of human soul, all alone in the world. I told him that I was sorry, but store rules didn't allow me to do so. I felt stupid and unkind saying this, but I valued my job. Just then, another man, standing behind the first, spoke up. If anything, he looked more pitiable. "Charge it to me," was all he said. What I had been feeling was pity. Pity is soft and safe and easy. Compassion, on the other hand, is caring in action. I thanked the second man but told him that was not allowed either. Then I reached into my pocket and paid for the biscuits myself. I reached into my pocket because these two men had reached into my heart and taught me compassion.
