Read the following article and select the best answer. Article: Increasingly, over the past ten years, people--- especially young people -have become aware of the need to change their eating habits, because much of the food they eat, especially processed food , is not good for the health. As a result, there has been a growing interest in natural foods: foods which do not contain chemical additives and which have not been affected by chemical fertilizers , widely used in farming today. Natural foods, for example, are vegetables, fruit and grain which have been grown in soil that is rich in organic matter. In simple words, this means that the soil has been nourished(...) by unused vegetable matter, which provides it with vitamins and minerals. This in itself is a natural process compared with the use of chemicals and fertilizers, the main purpose of which is to increase the amount--but not the quality--of foods grown in commercial farming area. Natural foods also include animals which have been allowed to feed move freely in healthy pastures . Compare this with what happens in the mass production of poultry :there are battery farms, for example, where thousands of chickens live crowded together in one building and are fed on food which is little better than rubbish. Chickens kept in this way are not only tasteless as food; they also produce eggs which lack important vitamins. There are other sides of healthy eating which are now receiving increasing attention from experts on diet. Take, for example, the question of sugar. This is actually unnecessary food. It is not that sugar is harmful in itself. But it does seem to be addictive: the quantity we use has grown steadily over the last two centuries and in Britain today each person consumes an average of 200 pounds a year! Yet all it does is provide us with energy, in the form of calories. There are no vitamins in it, no minerals, and no fibre. Question: People have become more interested in natural foods because _ . - they want to keep healthy - they want to taste all kinds of foods - natural foods are more delicious than processed foods - they want to return to nature
they want to keep healthy

(Question)
Read the following article and select the best answer. Article: Did you ever wonder how some of your favorite foods, products or toys came about? Believe it or not, they may have been an accident, or a failure of some other intention. Below, we found three mistakes we're thankful for turned out to be what they are. 1. Most historians hold that the Chinese invented fireworks in the 9th century when they discovered how to make gunpowder. Story has it that a Chinese cook accidentally mixed together what were then considered common kitchen items and noticed they burnt. When put tightly in a bamboo tube and lit, it blew up. 2. In May of 1886, a law led John Pemberton, a pharmacist , to rewrite the formula for "Pemberton's French Wine Coca," his popular headache treatment. Containing sugar instead of wine as a sweetener, the outcome became something for Coke, which was later mixed with carbonated water. His bookkeeper suggested the name Coca-Cola because he thought the two C's would look good together, which is how what we call Coca-Cola, a world -wide drink came into being. 3. During World War II, scientists at the University of Birmingham invented the magnetron--an important heat-producing part of the microwave oven . While working for Raytheon Corporation after the war, the American engineer Percy Spencer was testing the magnetron when a chocolate bar in his pocket melted. He went on to test other foods including popcorn kernels, and found it to be a much more efficient way to cook. In 1947 Raytheon came out with the first restaurant microwave oven, which was six feet tall and weighed 750 lbs.
