user: Question: Write a multi-choice question for the following article: Article: Man still has a lot to learn about the most powerful and complex part of his body -- the brain. It may be surprising to learn that it isn't age that makes you lose your memory. The reason could be that you have a "lazy" memory, not an old one. Like your body your memory improves with exercise. Once given plenty of exercise, the brain keeps its power. Before discussing how to improve the memory, let's look at how the brain works. There are two sides to the brain, the left and the right. The right side deals with the senses (what we see, hear, feel and smell). It's the creative and imaginative side. The left side is concerned with logic. It analyzes information and puts it in order. Some recent research suggests that we remember everything that happens to us. The problem most of us has is recalling events. Most forgetting takes place immediately after learning. An hour after learning something new, more than 50% has been forgotten. After a month, 80% has been forgotten, and so on. This shows revision is very important. If you revise new material you have learnt, you remember much more. So it's of vital importance to revise newly learned material often, and have frequent breaks. We best remember what we learn at the beginning of a learning period and at the point where we stop. After the break, revise what was learned before the break and then continue learning the new material. These breaks should happen every 20 or 45 minutes. Other experiments have shown the brain needs time to "digest" what has been learned. The time necessary for this is 5 to 10 minutes. After the break, the memory will have absorbed what it has just learned, and more will be remembered. During this period it is important to exercise the right side of the brain, because the left side is used during the learning period. Therefore you should relax. Listening to music, breathing in fresh air, and looking at a picture are all ways of using the other side of the brain. So when you are studying alone, make a plan which shows when to have breaks...

Question: Write a multi-choice question for the following article: Article: More than 2,400 years ago, a sickness struck Athens. The disease is said to have killed up to one third of all Athenians, including their leader Pericles. The huge loss of life  helped to change the balance of power between Athens and its enemy, Sparta, in the ancient world. Historians say the sickness began in what is now Ethiopia. They say it passed through Egypt and Libya before it entered Greece. Knowledge of the disease has come mainly from the writings of the ancient Greek historian Thucydides, who survived it. So what caused the fall of Athens? Now, a study based on genetic  testing says it was probably typhoid   fever.  Greek researchers announced the results. Journal of Infectious Diseases published the findings online last week. Researchers from the University of Athens tested human remains from an ancient burial place in the Greek capital. The researchers collected genetic material from teeth. They say tests found genetic evidence similar to that of the modern-day Salmonella  . Manolis Papagrigorakis led the University of Athens team. He says the findings throw light on one of the most debated mysteries in medical history. Typhoid fever is a life-threatening disease that is common today in developing countries. Experts say there are more than 21,000,000 cases each year.  Typhoid can be spread by food or drink that has been handled by a person infected with the bacteria  that causes it. Bacteria in human waste can pollute water supplies. So water used for drinking or to wash food can also spread the infection. Hand washing is important to reducing the spread of typhoid. And there are vaccines   that can help prevent it. Some people recover but continue to carry the bacteria. These carriers can get sick again. And they may continue to infect others. Doctors can do tests to make sure the bacteria has left the body.
Answer: Question: How many ways of spreading the typhoid bacteria are mentioned in the text?Options:A 3.B 4.C 5.D 6.Answer:A

Question: Write a multi-choice question for the following article: Article: Half of the world's population is affected by Asian monsoons , but monsoons are difficult to predict. American researchers have put together a 700-year record of the rainy seasons, which is expected to provide guidance for experts making weather predictions. Every year, damp air masses,known as monsoon,produce large amounts of rainfall in India, East Asia, Northern Australia and East Africa. All this wet air is pulled in by a high pressure area over the Indian Ocean and a low pressure area to the south. According to Edward Cook , a weather expert at Columbia University in New York., the complex nature of the climate systems across Asia makes monsoons hard to predict. In addition, climate records for the area are too recent and not detailed enough to be of much use. Therefore, he and a team of researchers spent more than fifteen years traveling across Asia, looking for trees old enough to provide long-term records. They measured the rings, or circles, inside thousands of ancient trees in more than 300 places. Rainfall has a direct link to the growth and width of rings on some kinds of trees. The researchers developed a document they are calling a Monsoon Asia Drought Atlas. It shows the effect of monsoons over seven centuries, beginning in the 1300s. Professor Cook says the tree-ring records show periods of wet and dry weather. "If the monsoon basically fails or is a very weak one, the trees affected by monsoons at that location might put on a very narrow ring. But if the monsoon is very strong, the trees affected by that monsoon might put on a wide ring for that year. So, the wide and narrow ring widths of the chronology that we developed in Asia provide us with a measure of monsoon variability." With all this information, researchers say they can begin to improve computer climate models for predicting the behavior of monsoons. "There has been widespread famine and starvation and human dying in the past in large droughts. And on the other hand, if the monsoon is particularly heavy, it can cause extensive...
