input question: Write a multi-choice question for the following article, with the given choices and answer: Article: With rising food prices, growing population and environmental problems, many people are worrying about how we will feed ourselves in the future. Don't worry. Scientists are trying to find some answers. Some scientists believe insects will become a staple of our diet. Insects provide as many nutrients as ordinary meat and a great source of protein , they also cost less to raise than cows and use less water. About 1,400 species are suitable as food for humans. Many people have already eaten insects as a part of their diet. Locusts are popular in Africa, wasps are a dish in Japan, and crickets are eaten in Thailand. The Dutch government is preparing for insect farms and has invested one million euros into research. In the future, land and fresh water will be in short supply. It is possible that people need to find a reliable food source in the ocean. Scientists have already found one at the bottom of the food chain---seaweed. It has long been a staple in Asia, and countries including Japan have huge seaweed farms. Such farms can easily work in other countries and be very successful. The great thing about seaweed is that it grows at an amazing rate. It's the fastest growing plant on earth. Scientists are also working in the lab to solve the problem of food shortage. A few years ago, European scientists successfully produced lab meat, also known as cultured meat. They grew muscle tissue using stem cells taken from cows. The experiment was funded by NASA to see if lab meat was a food astronauts could eat in space. In 20 years' time , lab meat is likely to become a popular dish of our diet. According to research, growing meat in a lab rather than slaughtering animals can greatly reduce greenhouse gases, along with energy and water use. People can also reduce fat from the meat and add nutrients. Options: A Two B Three C Four D Five Answer: B Three Question:???

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: "Fish stories" are stories of the greatest fish that a fisherman has almost caught, but for some reason, the fish always get away. Usually, these stories do not have much truth to them. One of the biggest fish stories in history was about a whale. In 1891, a ship hunting for whales in the South Atlantic Ocean found a very large whale. While the hunters were trying to kill the whale, it sank two small boats. One man drowned, and another man, James Bartley, was lost in the ocean. However, after the hunters finally killed the whale, they cut open the whale's stomach and found Mr Bartley inside. He was not dead! Several weeks later, Mr Bartley seemed to have gotten over his terrible experience. The only thing he could remember was that while he was inside the whale, it was very hot. The liquid from the whale's stomach had turned all of his skin snow white. Mr Bartley had to live with the effect from the whale for the rest of his life. Today, many people have heard about the strange experience of Mr Bartley and do not buy it. Not one real fact has been found to prove that the events ever took place described by the sailors. No scientist or newspaper reporter was ever able to talk to Mr Bartley, and all of the stories told in magazines about Mr Bartley's experience were explained by other sailors on the boat. Mr Bartley was probably not even a real person at all. In 1928, after the captain of the whaling ship had died, one man asked the captain's wife about Mr Bartley's story. The wife said that no man who had sailed on her husband's ship was ever swallowed by a whale. However, this has not stopped James Bartley's story from being repeated, and many people today still believe that it is true. Options: A The ocean water. B The whale's teeth. C The heat inside the whale. D The liquid in the whale's stomach. Answer: D The liquid in the whale's stomach. Question:???
