input question: Write a multi-choice question for the following article: Article: Have you heard of snake robots? Scientists and doctors are already using tiny snakes that coil through the human body armed with sharp surgical tools to perform operations on hearts, prostate cancer, and other diseased organs. The snake robots that carry tiny cameras, scissors and forceps, and even more advanced sensors are being developed. The next generation of the robots will be wireless, and will explore inside your body on their own--- not attached to any cables. For now, they are powered by cables that humans control. Experts say the day is coming when some robots will roam around the body on their own. But the experts in robotics say the new creations work best when they are designed for very specific tasks. Howie Choset has been researching and building robots, particularly snake robots. He believes that his snake robot and others like it can help reduce medical costs by making complex surgery faster and easier. Choset says his new design is smaller and more flexible than earlier models. The size of surgical robots allows surgeons to operate with far less damage to the body, helping the patient heal faster. Choset has also built larger snake robots designed for search and rescue, or just exploration. They can climb poles and trees and then look around through a camera in the head and slither through places that humans cannot reach. " We sent our snake robots into these caves in the Red Sea to look for evidence of ancient Egyptian ships," he said. " To me, archeology is like search and rescue, but everyone has been dead for 5,000 years." The doctors are very excited about the potential for surgical robots to do things that humans can't do. The variety of sensors available for surgical robots keeps expanding. As they get smaller, maybe one day they will be able to test chemicals or blood in the body, or even the electrical connections in nerves.???

input question: Write a multi-choice question for the following article: Article: Neither rain nor snow nor the dark of night can separate Tennessee postal carrier "Mailman Mike" from his 4-and-a-half-year-old friend Carter Lawson - or keep them from their appointments. For the past nine months, the two have teamed up every day in the preschooler's Knoxville neighborhood for a few minutes of delivering mail together and chatting with fellow neighbors. Lawson wants to be a mail carrier when he grows up, and in an inspiring story, his mom told us how mailman Mike Crenshaw has been a role model to her son. "Anyone could just be like 'Go away, kid', but Mike has really gone out of his way to talk with Carter," said Cassie Lawson of the United States Postal Service carrier. Little Carter even got his own uniform to match Mike's. "It's been really cute. I just couldn't believe he got a full mailman's costume," the postal service employee said. "Every letter carrier has stops he looks forward to and this is the one I look forward to every day," said Mike. "He's the end of my day, and the best part of my day. Not because it's the end, but because he's such a cute little guy." The man and the little boy's connection isn't a surprise to Fredric Rolando, president of the National Association of Letter Carriers. "Kids respond to mailmen because letter carriers are a friendly, uniformed part of the neighborhood who bring something to their house every day, and are someone they come to recognize and trust," Rolando said. "It's the same for the elderly, but in addition, letter carriers may be the only person they communicate with all day."???

input question: Write a multi-choice question for the following article: Article: Harry Houdini was a man who astonished and attracted many people during his life. Whether he was escaping from a locked box or making things disappear and reappear, he surely was entertaining. People thought that he must truly have some supernatural powers, but in fact, what Harry really had was drive. Harry was born in Budapest, Hungary, in 1874. His real name was Ehrich Weiss, the third of five children. His family moved to Wisconsin not long after his birth and when he was nine, he was tying ropes all over his backyard and learning amazing tricks to show his friends and neighbors. He visited the local locksmith, and when he had reached his teens he could pick almost any lock that was made. He also learned how to do card tricks. He and his brother, Theo, would often entertain at local parties and clubs for extra money. When Ehrich was 16, he came across a book that would actually change his life: the biography of France's greatest magician, Jean Eugene Robert-Houdin. It showed Ehrich that his hobby of magic and tricks could also be a career. Immediately, he changed his name to Harry Houdini. He and Theo headed out to make a living as magicians. In 1893, they performed at the Chicago World's Fair, and after that they traveled around giving magic shows for anyone willing to listen and pay. Theo grew restless, however, as the jobs became scarce, so he left. His timing was perfect since Harry had just fallen in love with a lovely woman named Bess who was just the right size for slipping in and out of the trunk they used in their magic tricks. They married immediately and then off they went, traveling with circuses and other road shows. Harry learned more and more tricks and spent much of his time reading and studying all kinds of locks, especially handcuffs. However, no matter what tricks they did or how hard they tried, Bess and Harry were not doing well. They tried to sell their shows for seven years and finally, in desperation, they went to Europe.
