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 _ . Yes or no, is the answer "stopping the greenhouse effect"?

No

Article: Whenever the house gets quiet, Mrs. Smith knows just where to find her 6-year-old daughter Maria: lost in the world of stories. "I like to read every time of the day," said Maria, a student at Creel Elementary School in Australia. Maria's headmaster, Mrs. White, wants each of her 850 students and their families to learn the love of reading this year. She wants reading at home to become an activity of choice in every family, even during holiday breaks. "I truly realize reading should be an important part of everyone's life, and nothing should stop it." said Mrs. White. "The aim we want most of all is to help children understand they can enjoy reading, as well as practice their skills," said Hannas, an education researcher. He suggested parents take their children to the library and allow them to pick out books that interest them. Each night, students take home two books to read with their parents or other family members. They have to return the books the next day with a signed note from their parents showing that the books were read, and have passing tests that check how well they understand the books. "We're trying to get parents into the habit of reading with their kids." said the headmaster. "Nothing is better than sitting on a sofa with your child and reading and laughing." Through books, Mrs. Smith, a parent, said she's able to give her two daughters more experiences than she could. "I think reading opens all the doors and creates imaginations in children," she said, "I think if you read well, you can succeed in anything in life." Question: To make sure how well the students understand the books, the school has to _ . Yes or no, is the answer "give the students tests"?
(Answer)
No
