input question: Write a multi-choice question for the following article, with the given choices and answer: Article: "How are you?" is a nice question. It's a friendly way that people in the USA greet each other. But "How are you" is also a very unusual question. It's a question that often doesn't need an answer. The person who asks "How are you?" hopes to hear the answer " Fine", even if the person's friend isn't fine. The reason is that "How are you?" isn't really a question and "Fine" isn't really an answer. They are simply other ways of saying "Hello" or "Hi". Sometimes, people also don't say exactly what they mean. For example, when someone asks "Do you agree?" the other person might think, "No, I disagree. I think you're wrong..." But it isn't very polite to disagree so strongly, so the other person might say "I'm not sure." It's a nicer way to say that you don't agree with someone. People also don't say exactly what they are thinking when they finish talking with other people. For example, may talks over the phone finish when one person says "I've to go now." Often, the person who wants to hang up gives an excuse "Someone's at the door." "Something is burning on the stove." The excuses might be real, or not. _ The excuse is more polite, and it doesn't hurt the other person. Whether they are greeting each other, talking about an idea, or finishing a talk, people don't say exactly that they are thinking. It's an important way that people try to be nice to each other, and it's part of the rule of the game of language. Options: A Always say what you mean B Don't disagree with people C Never say exactly what you're thinking D Be polite Answer: D Be polite Question:???
output answer: The rule of the game of language is probably " _ ".

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: Is your TV connected to the Internet? What about your chair or your fridge? It is possible that they are not. But in the future, most things in your home may be connected, as the so-called "Internet of things" is developing. The Internet of things may be coming sooner than you think. It is reported that during his speech earlier this year, Samsung CEO BK Yoon spent a lot of time talking about the Internet of things. He said that five years from now,every Samsung product will be part of the Internet of things, whether it's a washing machine or a vacuum cleaner . So, how do household objects that are part of Internet of things work? Well, think of a usual chair. When connected to the Internet, the chair warms up when it knows that the user has just walked into the room and is feeling cold. An Internet-connected camera, like a smart-home camera, could help people feel safer in their homes. It can recognize people's faces, and even can see when someone passes by in the dark. Then it can send you a message on your smartphone to let you know who's there. If the person is someone you don't know, it can tell you that, too. But according to MIT Technology Review, whether companies are connecting dog food bowls or security systems to the Internet, there may be problems. For example,many early connected-home devices don't have much built-in security, which means they could be hacked ,In addition, it could be difficult to get these devices to work together because they are made by different companies. To fight this, many companies have joined the Open Interconnect Consortium, which had 45 members by late 2014. So, picture this: you walk in through the front door of your home. The temperature changes to make you feel comfortable after a long day at school. Your favorite music starts playing for you. Do you think that this would be a good thing? It may happen sooner than you think. Options: A Companies which produce connected-home devices haven't joined together. B Connected-home devices may not work together and can easily get hacked. C Companies have difficulty connecting security system to the Internet.' D These new devices are produced by different companies. Answer: B Connected-home devices may not work together and can easily get hacked. Question:
Answer: What's the problem about the Internet of things?
