Write a multi-choice question for the following article: Article: Half the world's population could face a shortage of food by 2100 due to climate change, a new report by US scientists warns. Rapid global warming is likely to reduce crop production in the tropics and subtropics , according to Professor David Battisti of the University of Washington. "The most extreme summers of the last century will become common," he says. "We must immediately create crops that can bear heat and drought if we are to adapt in time," he writes in Science journal. "The stresses on global food production from temperature alone are going to be huge," said Mr. Battisti. "And that doesn't take into account water supplies stressed by the higher temperatures." He worked with Professor Rosamond Naylor on Food Security and the Environment, to examine the influence of climate change on the world's food supplies. They predict there is a greater than 90% probability that by 2100, the average growing-season temperatures in the tropics and subtropics will be higher than any temperatures recorded there to date. "We are taking the worst of what we've seen historically and saying that in the future it is going to be a lot worse unless there is some kind of adaptation," said Professor Naylor. "This is a powerful reason for us to invest in adaptation, because it is clear that this is the direction we are going in terms of temperature and it will take decades to develop new food crop varieties that can better bear a warmer climate." "In the tropics, the higher temperatures could be expected to cut production of the primary food crops by 20-40%," the researchers said. Rising temperatures are also likely to reduce soil moisture , cutting production even further. Three billion people live in the tropics and subtropics now, and their number is expected nearly to double by the end of the century. "You are talking about hundreds of millions of additional people looking for food because they won't be able to find...

Write a multi-choice question for the following article: Article: The book, Aliens Ate My Homework, is set in a small town in the United States. By the way the characters talk to each other and the description of items from their daily lives, I think the story takes place within the last 10 years. It is a story about a boy named Rod Allbright who goes to school like any other normal kid. Unfortunately, the class bully always picks on him because he is overweight. While he's working on a school project for the science fair, tiny aliens come, crashing through his bedroom window in a spaceship. They have come to the earth to get another alien, an evil one named BKR. He is known in other galaxies for his cruelties. Rod gets bullied throughout the entire novel. The bully's name is Billy Becker, who is also called BKR! Rod does not discover that Billy is a bad alien until later on. This book has lots of action and the main character is fun to read about. The most exciting part is when the aliens and Rod find out that BKR is Billy Becker and they skip school and go to search his house. They get caught when BKR comes home from school. He traps them in a storing device where he keeps his alien items. They break free of the device and escape from his house with some difficulty. Rod Allbright is fun to read about because he can never tell a lie. This gets him into trouble when the aliens eat his homework and he can't make up an excuse for the teacher. The main idea that the author shares is that there could be other galaxies out in the universe with intelligent life forms who could be almost the same as humans. In this book, the aliens are just like humans in the way they think even though they look different and have a different language. I have learned that if you are nice to people they will be nice in return. This is proven in the book because Rod is nice to the aliens and they return the favor.

Write a multi-choice question for the following article: Article: A disastrous competition is going on in England, with billions of dollars and hundreds of lives in danger. OK, that's not true. But competitors from around the world gathered on Thursday to compete for the title of 2012's World's Biggest Liar. Each participant is given up to five minutes to make up the best lie in the competition, which was started in honor of 19th-century Bridge Inn owner Will Ritson, who was reportedly famous for his lies. Competitors gather at the Bridge Inn every year for the competition, a small pub in northwestern England. Anyone can take part in the competition. Well, almost anyway; the reporters note that lawyers and politicians are banned, who is said to enjoy "an unfair advantage" in the proceedings . A study published this past July in the journal Evolution & Human Behavior found that nearly all lies are detectable through visible facial muscle reactions in the person telling a lie. "Thus, while interpersonal deception often is highly successful, signs of hidden emotional states are communicated clearly to the informed observer," the study concluded. A churchman of Carlisle reportedly holds what may be the greatest lie of all time in the competition, simply stating, "I have never told a lie in my life." In 2003, Abrie Krueger of South Africa became the first non-Brit to win the competition. Ironically, Krueger was accused by some of cheating. In 2006, comedian Sue Perkins became the first female to win the competition, telling a tale about people riding camels to work as a result of climate change. Last year's winning entry came from Glen Boyland, who told a lie about competing in a snail-racing competition with Prince Charles.
