Read the article and select the best answer. Article: In the 1500s, South American fishermen said that the sea became warmer every few years. They gave this special event a Spanish name 'El Nino', meaning 'the baby'. It is called 'the baby' because it arrives around Christmas. El Nino is a huge area of warm water in the middle of cold water in the Pacific Ocean. It happens every two to seven years. It moves around the ocean and becomes bigger and smaller at different times. This warm water affects the weather. It is always raining over El Nino. El Nino contains a lot of energy. Scientists think this energy is formed when wind comes from the northern half of the world. The winds blow across warm sea water in the south. When the strong wind hits the warm water, violent weather happens. Scientists think that El Nino existed for many thousands of years. El Nino affects every person in the world because it affects the entire world's weather. It can bring the rain that farmers need. It can bring storms that destroy homes. It can mean that fishermen cannot catch fish, and it can bring floods. There is nothing we can do about El Nino. It is an event of nature. We can help the world's weather by trying to stop the greenhouse effect and air pollution. The most important job for scientists is to learn how to predict when El Nino is going to bring dangerous weather. Then, people can try to prepare for storms, floods and droughts. New technology like satellite pictures and temperature measuring equipment can help. Still, it is very hard to say when or where El Nino will cause damage. Question: We can help the world's weather by _ . Options: A: finding out more about El Nino B: being careful during the floods C: driving cars D: stopping the greenhouse effect

Paper money also took him by surprise, since it was not yet in use in the West at that time. Homes were heated with "black stones... which burn like wood." These stones were coal, and most of the Europeans knew little about it then. After 17 years in China, Marco and his family finally returned to Venice in 1292. After he returned home, Marco completed a book about his trip, full of facts about his wonderful experiences in China. Question: The Polos finally got to China in _ .
