input question: Write a multi-choice question for the following article, with the given choices and answer: Article: A classic joke goes like this: A nurse rushes into an exam room and says, "Doctor, doctor, there's an invisible man in the waiting room." The doctor says, "Tell him I can't see him." Pretty simple, right? Here's how I tell it: "A nurse--her name is Joyce--feels a presence in the waiting room. She looks around but sees nothing. She jumps up from her desk, carefully replaces her chair, and runs down the lavender-hued hallway to the doctor's office. She knocks on the door. No response. He's not there. Where can he be? She continues down the hall, admiring a lithograph of an 18th-century Mississippi paddleboat along the way." By this time, my audience has left, but I soldier on. "She bursts into the exam room and says, 'Doctor, doctor!' The doctor, I should mention, is a urologist with a degree from Ohio State, which is where my nephew ..." You get the idea. I'm an embellisher. I can't leave a simple gag alone. I'm not the only joke-challenged member of the family. My sister's worse than I am. Her problem: She can't remember them. "'A nurse rushes into an exam room and says...'Uh, let me start all over again. 'A nurse rushes into a waiting...'No, it's not the waiting room. She just came from the waiting room. Let me start all over again. 'A doctor rushes into...' No, wait..." My uncle's different. He's guilty of taking a perfectly fine joke and selling it as the second coming of Oscar Wilde, "Okay, this is a good one. Ready? No, really, ready? Okay, fasten your seat belts. Ready?'A nurse...'Got it? A nurse? Okay, ready?'A nurse rushes into an exam room and says, "Doctor, doctor, there's an invisible man in the waiting room."' Now, this is where it gets funny. Ready?" No one is ever ready, so they leave before he gets to the punch line. My father's on Wall Street, so he hears all the jokes before they hit the Web. And he lets you know he knows them all by telling you all of them. He also knows that most people don't like jokes. So he slips them in under the radar: "I was chatting with Ben Bernanke the other day....

Write a multi-choice question for the following article, with the given choices and answer: Article: A smart phone is a mobile phone built on a mobile operating system, with more advanced computing abilities than a common phone. The first smart phones enabled the users to send and receive emails. Later models added the function of portable media players, pocket video cameras, and GPS navigation units to form one multi-use device. Many modern smart phones also include touchscreens and web browsers that display web pages. A recent report says we spend an average of two hours and 40 minutes each day looking at a smart phone. That doesn't mean making calls, but playing phone games and browsing the Web. Nowadays we always find people checking emails in a restaurant, taking a picture of the food when it arrives, or checking a message during a conversation instead of traditional communication. It's no secret that our lives are being affected by our smart phones _ . However, this phenomenon has never been presented so vividly as in the short YouTube film I Forgot My Phone. Despite only being online for a few days, it's already been viewed more than 10.5 million times. Whether it will be screened in the cinema remains to be seen. Ironically, YouTube's data show that the site gets a billion views per day from mobile devices, so a lot of those people watched it on their phones. The short film, written by and starring actress Charlene Deguzman, shows groups of people in various social situations, the majority of whom are absorbed in their phones instead of the world around them. To a certain extent, we all do it. Options: A check emails B send messages C find the destination D watch a video Answer: B send messages Question:

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Robert Louis Stevenson was born in Edinburgh in Scotland in 1850. He had to end his college studies because his health was poor. He began to travel, looking for a place that was good for his health. And he wrote about his travels. Inland Voyage(1878) was about journeys by canoe on the rivers and canals of Belgium and France. Travels with a Donkey in the Cevennes followed it in next year. People loved his travel books, and they also found his poems beautiful. In 1879 he travelled to California in a very uncomfortable ship and then by train across the United States to San Francisco. He married in California, but his poor health made him and his wife travel again. Readers of his travel books and poetry were surprised when Treasure Island came out in 1883. It was not at all like his earlier writing, but both children and grown-ups loved it. Treasure Island was finished in Switzerland. Stevenson then continued to travel. He loved the islands of the southern Pacific Ocean, and he found that his health was better there. In the end, he and his wife made their home in Samoa. It was there that he wrote Kidnapped(1886), the story of David Balfour and Alan Breck. It was followed (but not immediately) by Catriona, which continues the story of David Belfour and tells of other exciting adventures of David and Alan, and of David's love for Catriona Drummond. In between the two stories about David Belfour came another surprising book, the "thriller" called The Strange Case of Dr Jekyll and Mr Hyde. Stevenson died in Samoa in 1894, and he is buried there.
