Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: As for older people, some of the applications are hard to use because they didn't grow up with them. They don't have simple models of how it should work. They don't know what to do when it doesn't work. I think there is huge potential, so I have designed some for them. The ability to connect to friends, who remember the same movies, news and music, is really important, especially as people get older. They end up in retirement homes and they aren't always close to their friends. Allowing the network to help them connect with friends and family members is a really powerful thing. My wife likes using the Internet, although it took me years to get her to use e-mail. She was born with normal hearing, but lost it when she was three years old. She was totally deaf for many years until 53 when she got ear implants .They work really well. That is a big change for her. Before then, her friends couldn't call her on the phone, so they insisted that she use e-mails to communicate with them. The younger people don't even think of this as technology. It's just there, and they use it .There's been a very interesting change in communication styles between the old and the young .A woman named Sharryturkle wrote about this phenomenon .There are some kids who are now in their teens and are tending not to make phone calls. And they think of e-mail as old-fashioned and slow. The reason why teens don't make phone calls seems to be that they don't know what to say. When they call they often pause for a while. On the other hand, texting is considered proper, and it's OK if you don't answer. You might have been distracted .It's not considered rude, but it's considered unusual if you're in this kind of voice conversation and simply stop talling. Options: A didn't like to talk on the phone B didn't know how to use the phone C couldn't move or meet with her friends D was deaf and couldn't hear others on the phone Answer: D was deaf and couldn't hear others on the phone Question:

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: How can you hear your friends' voices when they are far away and you can't make a long--distance call? Besides the web camera system with your computer, we have a new high-tech way to solve the problem and ease your pain of missing them. The Japanese company Combiwith created a system-- . It makes people in pictures speak! The "talking picture" has a special pen. It is actually a pen-shaped scanner. It can scan information in special--made pictures. A connected player will then play the information out loud. First, you need to take a picture and record what you want to say with the company. The company will then make special barcodes onto your picture(you can't see those codes). Those codes are your voice and your words. When you hold up the pen to scan your picture with barcodes, a player connected to the pen will start to play. It plays things you've recorded. That way the invention makes the "you" in the picture speak! Do you want your friends and families talking out of pictures? Have them make pictures like that, and you can hear them whenever you want, only with the "talking picture" system. The system can play messages for up to 12 minutes. "The pictures would be useful for those who hope to hear the voice of someone living far away," said Mayumi Fuji, a spokeswoman for the company. "Grandparents, for example, longing to know about their grandchildren, would be happy to hear their voice when they see the picture," Fuji said. But it is troublesome to go to the company for taking a special picture first. And, it is much more expensive than using a telephone. The photo with barcodes costs between 17,040 and 17,990 yen (160 and 169 dollars). The larger picture you want, the more you pay. Now, just raise a finger, lonely people can have their loved ones speak out of pictures. But, whether the "talking picture" is practical or not, let's wait and see. Options: A The picture can play what's been recorded as if the person in the picture "talks". B You can have a talk with the person in the picture whenever you want to. C The picture can tell you wonderful stories to ease your pain. D The picture can tell what's on your mind when you are looking at it. Answer: A The picture can play what's been recorded as if the person in the picture "talks". Question:???
output answer: What does "talking pictures" mean according to this article?

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Many adults enjoy a cup of coffee to have extra energy on a sleepy morning, and astronauts are no exception. But having a drink in space isn't as easy as it is on the earth. You have to come up with a whole new way to drink, and that' s what scientists are trying to do. "The coffee would be very hard to control in a normal cup," said physics professor Mark Weislogel. "You' d have to shake the cup toward your face and hope that some of the hot liquid floats toward your mouth. When it comes to guessing what liquids will do in new systems, we are often in the dark. " Weislogel believes that creating a big zero - gravity cup would help improve the lives of astronauts in space, so he and other researchers per formed a series of experiments with liquids on the International Space Station (ISS) to see how they move upwards on surfaces in zero gravity. In one of the tests, they placed two surfaces very close together to create a very narrow tunnel. They wanted to see if liquid would easily flow up the tunnel. In another test , the researchers tried to figure out the best angle to place the narrow tunnel at so that the liquids would travel along the corners. The end result is a cup that doesn't look like a normal coffee cup at all. One side of the cup has a very sharp angle and, in zero gravity, the liquid naturally "flows" up that angled side of the cup, right up to the drinker' s lips. The zero-gravity coffee cup is currently being tested on the ISS by astronaut Don Pettit, who worked with the researchers and helped them invent it. " As you sip , more liquid keeps coming , and you can enjoy your coffee in a weightless environment - clear down to the last drop, " said Pettit, who thinks that future humans on Mars will be using this kind of cup to drink during celebrations ! Options: A When humans will drink coffee on Mars. B How humans will drink coffee in zero gravity. C How experiments lead to unexpected patents. D When a normal cup can be used in space. Answer: B How humans will drink coffee in zero gravity. Question:
