input question: Write a multi-choice question for the following article, with the given choices and answer: Article: George Washington Carver showed that plant life was more than just food for animals and humans. Carver's first step was to analyze plant parts to find out what they were made of. He then combined these simpler isolated substances with other substances to create new products. The branch of chemistry that studies and finds ways to use raw materials from farm products to make industrial products is called chemurgy. Carver was one of the first and greatest chemurgists of all time. Today the science of chemurgy is better known as the science of synthetics . Each day people depend on and use synthetics made from raw materials. All his life Carver battled against the disposal of waste materials, and warned of the growing need to develop substitutes for the natural substances being used up by humans. Carver never cared about getting credit for the new products he created. He never tried to patent his discoveries or get wealthy from them. He turned down many offers to leave Tuskegee Institute to become a scientist in private industry. Thomas Edison, inventor of the electric light, offered him a laboratory in Detroit to carry out food research. When the United States government made him a collaborator in the Mycology and Plant Disease Survey of the Department of Agriculture, he accepted the position with the understanding that he wouldn't leave Tuskegee. An authority on plant disease--especially of the fungus variety--Carver sent hundreds of specimens to the United States Department of Agriculture. At the peak of his career, Carver's fame and influence were known on every continent. Options: A It mainly tells us about Gorge Washington Carver, a great chemurgist. B It mainly tells us about chemurgy. C It mainly tells us about the research made in Tuskegee. D It mainly tells us about the development of making synthetics. Answer: A It mainly tells us about Gorge Washington Carver, a great chemurgist. Question:???

Write a multi-choice question for the following article, with the given choices and answer: Article: A friend of mine was fond of drawing horse. He drew the horses very well, but he always began the tail. Now it is the Western rule to begin at the head of the horse, that is why I was surprised. It struck me that it could not really make any difference whether the artist begins at the head or the tail or the belly or the foot of the horse, if he really knows his business. And most great artists who really know their business do not follow other people's rule. They make their own rules. Every one of them does his work in a way peculiar( ) to himself; and the peculiarity means only that he finds it more easy to work in that way. Now the very same thing is true to literature. And the question, "How shall I begin?" only means that you want to begin at the head instead of beginning at the tail or somewhere else. That is, you are not yet experienced enough to trust to your own powers. When you become more experienced you will never ask the question, and I think that you will often begin at the tail -- that is to say, you will write the end of the story before you have even thought of the beginning. Options: A How to draw a horse B How to write a story C How to make your own rules D Trust to your own powers Answer: D Trust to your own powers Question:

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: Ceaseless technology. A punishing workweek. That to -do list that keeps multiplying. It is no wonder many of us find it difficult to have a sufficient amount of sleep. But will sleeping more on the weekend make up for hours of lost snoozing ? One sleep expert, W. Christopher Winter raised the question. Sleeping binge Getting eight hours of shut-eye each night is generally recommended, but many people don't. As the week rolls from Monday to Friday, they accumulate a sleep debt. Spending a few extra hours in bed on a Saturday morning, people assume, will help them " catch up" on lost sleep. They're likely right, " Nobody knows how long the horizon is, probably a few nights, but studies show that recovery sleep in the short term does work," says Dr. Winter, a member of the American Academy of Sleep Medicine. Sleep banking Recent data suggests that banking sleep in advance of a long night can actually offset upcoming sleep deprivation . If you knew you were going to have to stay up all night on a particular day, for example, you could sleep for 10 hours a day for multiple days before the event, and be fine, Dr. Winter says. Just plan ahead. Routine naps A scheduled nap is healthier than catching up on or banking sleep. " Because sleep extension can make you feel groggy , I always recommend a short nap [if a person feels they need it ], at the same time, every day," says Dr. Winter. He adds that 25 minutes is ideal. " When you schedule a short nap, your body anticipates it and slows down, without falling into a deep dream sleep," he says. That refreshing, scheduled break is better than an occasional weekend lie-in. " The body likes routine," he says, " When it's prepared, it works more efficiently." Options: A a nap have no effect on work B a nap have effect on work C recovery sleep does work D recovery sleep doesn't work Answer: C recovery sleep does work Question:
A: Research shows that in the short term _ .

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: The cost of college textbooks has risen sharply from 2002 to 2014. As a result, students have to look for other less expensive options , such as renting books. Now, they find another way, that is, using textbooks on the Internet, uploaded by other students. It is hard to know how popular this practice will be, but many college students around the country are uploading their expensive college textbooks onto the Internet, so that other students can download them for free and avoid the big fees. A year ago, a student wrote a blog called Children of the Stars about a professor who insisted that students buy the newest edition of a specific sociology book for more than $200 and didn't allow them to purchase an older paperback edition of the same book for $5. The student wrote, "The newest edition of the book is so expensive. Fortunately, we found the electronic one online, which is very cheap. This is why we downloaded. " The blog is followed by a list of websites where people can download books. Curious about how varied the selection of books was and how easy it was to download them, Vocativ.com decided to do an experiment. The workers of it picked five typical and important courses of freshmen and tried downloading all these textbooks on the websites offered by the student who wrote Children of the Stars. They typed the titles of these textbooks into a computer, and found them immediately. Within minutes, they had four textbooks on their hard drive. It is illegal to upload or download copyrighted materials without permission, but students still do it due to its advantages. Besides, schools haven't taken action to stop it. Options: A Downloading textbooks was easy. B Downloading textbooks was illegal. C Downloading textbooks was expensive. D Downloading textbooks was impossible. Answer: A Downloading textbooks was easy. Question:
