input: Please answer the following: Write a multi-choice question for the following article: Article: Ever since man began to use the telephone, there have been new problems arising from the carrying of messages. At first, each message was carried by a pair of overhead wires. As a result, telephone exchanges were soon surrounded by thousands of wires. The wires were then replaced by cables ,each containing many pairs of wires. Each cable is capable of carrying many messages. These cables, laid underground, replaced the overhead wires. The more _ telephone services have become, the more demand for these services has increased, particularly the demand for long-distance services. In China, for example, this growth is now over 30% every year. Long-distance telephone exchanges are usually in crowded cities, where is not easy to lay new labels for expanding services. The use of radio to send telephone message and to link all telephone exchanges makes it possible to get rid of overhead wires and some underground cables. Now man has invented the microwave system ( ). In a microwave system messages from various places can be brought together, and then they are sent out and received by radio. After that, the messages are split into their original form. Finally, they are sent to the places where they are going to be sent.

Please answer this: Write a multi-choice question for the following article: Article: For most city people, the elevator is an unremarkable machine that inspires none of the enthusiasm or interest that Americans afford trains, jets,and even bicycles. Dr. Christopher Wilk is a member of a small group of elevator experts who consider _ a misunderstanding. Without the elevator, they point out, there could be no downtown skyscrapers or tall buildings, and city life as we know it would be impossible. In that sense, they argue,the elevator's role in American history has been no less significant than that of cars. In fact, according to Wilk?the car and the elevator have been locked in a "secret war" for over a century, with cars making it possible for people to spread horizontally ,and elevators pushing them toward life in close groups of towering vertical columns. If we tend to ignore the significance of elevators, it might be because riding in them tends to be such a brief, boring, and even awkward experience^one that can involve unexpectedly meeting people with whom we have nothing in common, and an unpleasant awareness of the fact that we're hanging from a cable in a long passage. In a new book, Lifted, German journalist and cultural studies professor Andreas Bernard directed all his attention to this experience, studying the origins of elevator and its relationship to humankind and finding that riding in an elevator has never been a totally comfortable experience. "After 150 years, we are still not used to it", Bernard said. "We still have not exactly learned to cope with the mixture of closeness and displeasure." That mixture, according to Bernard, sets the elevator ride apart from just about every other situation we find ourselves in as we go about our lives. Today,as the world's urban population explodes,and cities become more crowded, taller, and more crowded, America's total number of elevators--900,000 at last count, according to Elevator World magazine's "2012 Vertical Transportation Industry"are a force that's becoming more important than ever. And for the people who really, really...

input question: Write a multi-choice question for the following article: Article: India is traditionally a tea-drinking country. But, it is now gaining a new taste for coffee. This has led international coffee companies to consider opening businesses in the huge market. Local business people are also hoping to profit from the country's tea-drinking habits. They want to open new stores that offer tea. It is ten thirty in the morning in India. Two cafes are within meters of each other, near a college in New Delhi. And they are selling a lot of tea. Their main customers are undergraduate students. "We have a lot of break between classes, so whenever we get time, we just go and we enjoy ourselves. It's a lot of fun , especially when you are with people you enjoy spending time with." In the past ten years , cafes have become increasingly popular in India. The country's huge young population have quickly taken to the coffee culture. Coffee stores have spread from major cities like New Delhi and Mumbai to smaller towns.

Indians drink eight times more tea than coffee. They have been drinking tea for more than one hundred and fifty years.
