She found that 80% of the students thought sitting on the balls helped them pay more attention to what they were learning. The teacher, Pisa Witt, felt so strongly about the use of balls as chairs, she started Witt Fitt. This company encourages the use of the balls. And the company educates not only teachers but also students on how to use them. "Our products are used in 24 states, three provinces in Canada, Puerto Rico and Japan," says Witt, " Research shows that sitting on the balls makes them sit up straighter . You can slouch on a ball," says Witt, "but it feels bad." Because the students are moving, their blood increases.

Write a multi-choice question for the following article: Article: Sometimes life gets a little dull. What used to be fun and different becomes boring. That is the time to look for something new. It is the time for a big idea to get your mind off everyday life. So why not search for extraterrestrial intelligence? Or even better, why not get your computer to do it for you? Over two million people have joined the Search for Extraterrestrial Intelligence(SETI)project. Based in California, the SETI project analyzes information taken from a giant radio telescope based in South America. Its task is to look for signals from outer space that might prove that life exists on other planets. Processing this information is far too big a job for one computer. So the SETI project workers divide the work among volunteers who visit their website. Each computer gets some information to work out from the SETI network through the Internet. This process is often known as "meta-computing". It is a wonderful thought. You are sleeping, eating a meal or going out with friends. All this time, your computer is searching the stars for signs that might show something is out there trying to get in touch. Volunteers are proud of being involved in the SETI project. It shows that they understand the potential of computing. They know that it is more than just a way of working or playing games. Meta-computing may also be creating intelligence as well as looking for _ . This idea is based on the theory that human intelligence is created by the way in which different parts of the brain communicate with each other. As the saying goes, "The whole is more than the sum of its parts." People who join the SETI project sometimes wonder whether their computer will become part of a huge network that has learned to think for itself.

Write a multi-choice question for the following article: Article: Warm water freezes more quickly than cold water. Sir Francis Bacon said that almost four hundred years ago. But few people believed him until 1970. In that year Canadian scientist Geoge Kell proved the English physicist was right. Dr Kell filled one open bowl with cold water. He filled another with warm water. He put both bowls to the same low temperature. The warm water froze first. The lack of covers on the bowls was the secret . Some of the warm water changed into vapor. It evaporated into the air. This meant that less of the warm water was left to freeze. And so the warm water froze faster than the cold water.
Ans: Question: Warm vapor can't freeze faster if the bowls are _ .Options:A fullB coveredC put outsideD changedAnswer:B
