Article: According to some predictions, human beings will die out in 2012. Nearly all people think it's impossible, but there are some more earthquakes in recent years. Animals can predict the weather or other natural events. It may sound strange, but farmers living in the countryside think so. For hundreds of years , they have observed animals. "Animals ' behavior can be connected to future weather conditions or events." They say. For example, if cows lie down, a rainstorm is coming. There are many traditional stories connecting animals and natural events. Many people think that these stories don't have scientific evidence( ) at all. Scientists, however, are beginning to take another look at some of these ideas. A Japanese earthquake researcher named Kiyoshi Shimamura noticed an increase in dog bites a short time before earthquake hit. Then he did research on twelve public health centers in Kobe, Japan. These health centers treated people after the 1995 earthquake . He got some interesting information about the month before the big earthquake: treatment for animals' bites had increased . In fact, aggressive behavior in dogs, such as biting and barking loudly , jumped 60 percent. There are also other changes in animals' behavior before the earthquake. For example, fish began swimming together in large groups , but only in the middle of the water and not near the edges. Birds flew away from their nests for many days, leaving their eggs unprotected . These animals' behavior suggests that animals may be able to predict natural events better than people. Question: What would cows behave before a rainstorm? Yes or no, is the answer "Lying down"?
No

Article: Most of us probably live without vegetables, but a world without chocolate? Now that would be hard! According to chocolate makers it could happen if we don't act soon. There are two main causes of the chocolate shortage --- chocolate's growing popularity and less production of cocoa, the plant from which chocolate is made. With more and more people in India and China loving chocolate, not much can be done about the first cause. Therefore, the only thing we can do is to increase cocoa production. However, new plant diseases and little rain in Ivory Coast and Ghana, the world's largest producers, have reduced cocoa production by 40 percent in the past 10 years. What's worse, many cocoa farmers in Africa and other cocoa-producing countries like Indonesia and Venezuela are changing to easier-to-grow crops such as corn or rubber. This way, the farmers can make more money. To prevent more farmers from changing, researchers at the newly opened International Cocoa Control Centre, in the UK, are trying to create new cocoa plants that are stronger and faster growing. But first they must make sure the new plants are safe to grow. This takes a long time. First, each new plant is stored at the Control Centre for six months to make sure it is healthy. It is then planted in the Centre's fields, studied and tested for another two years. Only after scientists are certain that they're disease-free, will the plants be sent to farmers in West Africa or wherever else they are needed. To create new stronger types of cocoa, scientists at the Centre are combining the best parts from different cocoa plants. Though the world is facing a serious chocolate shortage, there is now hope! Question: In which countries has chocolate become more popular in recent years? Yes or no, is the answer "China and India."?
No
