Question: Write a multi-choice question for the following article, with the given choices and answer: Article: Suppose you are reading a book. Suppose, too, you suddenly close your eyes. Can you still see the book? "Of course not," you will say. But can you tell why? You would probably say, "When I close my eyes my eyesight cannot get out of my eyes to get to the book. " But this explanation is wrong. You cannot see any object unless light from that object gets into your eyes. Some of the things you see give off light of their own. The sun, the stars, a lighted lamp are examples of that can be seen by their own light. Such things are luminous. Most of the things you see are not giving off light of their own. They are simply reflecting light that falls on them from the sun or some other luminous body. The moon, for example, does not give off any light of its own. It is non-luminous. You see it because sunlight falls on it and some of it reflects in your direction. So moonlight is only second-hand sunlight. When you look at a book, it sends to your eyes some of the light which falls on it, and you see the book. If light could be kept out from where you are so that there would be no light for the book to reflect, then you could not see the book even with your eyes wide open. Light travels so fast that the time in which it travels from the book you are reading to your eyes is so short as if there were no time at all. Light reaches us from the moon, which is about 380,000 kilometres away, in only a little more than a second. Options: A 380,000 B 300,000 C 400,000 D 190,000 Answer: B 300,000 Question:
Answer: Light travels about _ kilometres per second.

Many people on the island had a disease called beri-beri. He was going there to try and find a _ . At first, Eijkman thought some kind of germ caused beri-beri. He raised some chickens. He didn't eat them, but made experiments on them. The local people were quite surprised at that. One day he noticed that his chickens became sick when they were fed the food most Javanese ate -- refined white rice . When he fed them with unrefined rice, also known as brown rice, they recovered. Eijkman realized that he had made an important discovery -- that some things in food could prevent disease. These things were named vitamins . The Javanese were not getting enough vitamins because they had actually removed the part that contains vitamins. Later, other diseases were also found to be caused by the lack of vitamins in a person's food. Today many people know the importance of vitamins and they make sure they have enough vitamins from the food they eat. If they don't, they can also take vitamin pills. Options: A eat vitamin pills B eat more meat C eat some chicken D eat more rice Answer: A eat vitamin pills Question:
