input question: Write a multi-choice question for the following article: Article: Howling is a behavior commonly observed among a wolf pack . As pack animals, wolves work together to hunt and rely on howling as an important means of communication among each other. There are different explanations of a wolf's howl and it appears that there may be more to discover. One theory is that wolves howl to bond better together. It's almost as if howling together helps the pack stay together, perhaps something similar to people feeling a sense of involvement with each other when singing a song together. But this theory may be wrong, explains Fred H. Harrington, a professor who studies wolf behavior. Indeed, there have been times when wolves have been seen one moment howling in a chorus, and the next, quarreling among each other. It appears that usually the lowest-ranking members of the pack may actually be "punished" for joining in the chorus at times. So is howling a way to strengthen a social bond or just a way to reconfirm status among its members? --Why do wolves howl for sure? What is clear, however, is that howling is often used among packmates to locate each other. Hunting grounds are distant and it happens that wolves may separate from one another at times. When this happens, howling appears to be an excellent means of gathering. Howling, interestingly, is a contagious behavior. When one wolf starts to howl, very likely others will follow. This is often seen to occur in the morning, as if wolves were doing some sort of "roll call" where wolves all howl together to report their presence.???

input question: Write a multi-choice question for the following article: Article: "I can't live without my mobile phone!" is what I often hear people say as they talk about how mobiles have become an essential part of their lives. The all so common sight of heads bent, eyes staring at mobile screens and fingers busy tapping away repeats itself across major cities around the world. Whenever there is a moment to spare while on the train, taxi or waiting in a queue, people busy themselves with their mobile phones. Some people believe our unhealthy obsession with mobile phones is destroying how we appreciate the little things in life or miss the moments that matter. The truth is that technology overall should be seen as just a tool to improve our lives. Mobile phones have certainly had a great influence on our lives, but I truly believe it is for the better. It's changed the way we communicate, whether for work or play. We are now less constrained by time and geographical location. With my mobile phone, I can dial into conference calls while stuck in a traffic jam, or reply to urgent e-mails while on the go. I can send a text message or share photos and videos with friends who aren't living in the same country. My phone calendar keeps my life organized, and even Facebook, Twitter, and instant messaging are now accessible from mobile phones! The mobile revolution isn't just changing the lives of urbanities like myself. I know of a young Bangladeshi woman named Shompa Akhter who is crazy about fashion and design. She dreamt about starting her own business and she did just that, opening a shop in Kushtia featuring her own creations. Dealing with supplies in different towns was a problem for Shompa --- purchase orders had to either be hand delivered or mailed out to supplies. Shompa also found it tough publicizing her business to potential customers outside her town. But once she learnt to operate the mobile phone, she was addicted. The 25-year-old businesswoman now stays in touch easily with her suppliers. Mobile e-mail is a blessing in her life. Who would have thought that mobility could...???

input question: Write a multi-choice question for the following article: Article: Here below we will talk about the American expressions using the word "Dutch". Many of the "Dutch" expressions heard in American English were first used in England in the seventeenth century. Britain used to be called "empire on which the sun never sets",which gained its supreme power mostly by its naval( )military forces. The period of the Anglo-Dutch Wars was a time of fierce naval competition between England and the Netherlands. At that time, the British used "Dutch" as a word for something bad, or false, or mistaken. A "Dutch agreement" was one made between men who had drunk too much alcohol. "Dutch courage" was the false courage produced by the effects of drinking alcohol. And "Dutch leave" was what a solider took when he left his base without permission. Some of these old expressions are still used today with a little different meaning. "Dutch treat" is one example. Long ago, a Dutch treat was a dinner at which the invited guests were expected to pay for their own share of the food and drink. Now, Dutch treat means that when friends go out to have fun, each person pays his own share. Another common expression heard a few years ago was "in Dutch", which simply referred to the country then. Nowadays, if someone says to you, you are in Dutch, they are telling you that you were in trouble. An important person, a parent or teacher perhaps, is angry with you. Some of the Dutch expressions heard in American English have nothing to do with the Dutch people at all. In the 1700s, Germans who moved to the United States often were called Dutch. This happened because of mistakes in understanding and saying the word "Deutsch", the German word for German. Families of these German people still live in the eastern United States, many in the state of Pennsylvania. They are known as the Pennsylvania Dutch. During the American Civil War, supporters of the northern side in the central state of Missouri were called Dutch, because many of them were German settlers. In California, during the Gold Rush, the term Dutch was used...???

input question: Write a multi-choice question for the following article: Article: What is your favorite color? Do you like yellow, orange, or red? If you do, you must be an active person who enjoys life. Do you like blue? Then you are probably quiet, shy, and would rather follow than lead. Colors do influence our moods . A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress brings warmth and cheer to the saddest winter day. On the other hand, black is depressing . There was a black bridge over the Thames River, near London. The number of people who killed themselves on that bridge used to be larger than on any other bridge in the area -- until it was repainted green. Light and bright colors make people not only happier but also more active. In the factory, the workers will work better, harder, and have fewer accidents when their machines are painted orange rather than black.???
