Yet the dream remains alive: if all men speak the same language, they can do anything.L.L.Zamenhof from Poland was among the men who this dream.He developed Esperanto between 1877 and 1885. As the most successful man-made world language, it is spoken by over two million people around the world.Last month, the World Esperanto Congress , dealing with language rights, ended in Sweden.The 2004 conference will be held in Beijing.Most Esperanto speakers are in Central and Eastern Europe and in East Asia, particularly Chinese mainland. Esperanto has two advantages.First, it's easy.Each letter has exactly one sound and there are just 16 basic grammar rules.The second advantage is that it belongs to no one country.But Esperanto has only reached a small number of people compared with natural languages widely used around the world-such as English or Chinese.While these languages are deeply connected with their nations and cultures, Esperanto doesn't have this background. Will Esperanto really become a global language? It remains a question. Options: A More people speak English than Esperanto. B Esperanto words are easier to spell. C Esperanto has fewer grammar rules. D Esperanto is not supported by any country or culture. Answer: D Esperanto is not supported by any country or culture. Question:

The time difference between two zones is one hour. You can have days with more than twenty-four hours and days with fewer than twenty- four hours. You can have weeks with more than seven days and weeks with fewer than seven days. If you make a five-trip across the Atlantic Ocean , your ship come into a different time zone every day. As you come into each zone, the time changes one hour. If you travel west, you set your watch back. If you travel east, you set it ahead. Each day of your trip has either twenty-five or twenty-three hours. If you make a trip by ship across the Pacific Ocean , you cross the International Date Line. This is the point where a new day begins when you cross the line, you change one full day. If you travel east, today becomes yesterday, if you travel west it is tomorrow.

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: When I was seven, my father gave me a Timex, my first watch. I loved it, wore it for years, and haven't had another one since it stopped ticking a decade ago. Why? Because I don't need one. I have a mobile phone and I'm always near someone with an iPod or something like that. All these tell the time -- which is why, if you look around, you'll see lots of empty wrists ; sales of watches to young adults have been going down since 2007. But while these wise people have realized that they don't need them, others -- including some distinguished ones of our time -- are spending total fortunes on them. Brands such as Rolex, Patek Philippe and Breitling command shocking prices, up to PS 250.000 for a piece. This is ridiculous. Expensive cars go faster than cheap cars. Expensive clothes hang better than cheap clothes. But these days, all watches tell the time as well as all other watches. Yes, you may say expensive watches will come with some extra functions -- but who needs them? How often do you dive to 300 metres into the sea to test its function of waterproof, or need to find your direction in the area around the South Pole by using its compass? So why pay that much of five years' school fees for watches that allow you to do these things? If justice were done, the Swiss watch industry should have closed down when the Japanese discovered how to make accurate watches for a five-pound note. Instead, the Swiss re-invented the watch, with the aid of millions of pounds' worth of advertising, as a message about the man ---- usually a famous star, wearing it. Rolexes are for those who spend their weekends climbing icy mountains; a Patek Philippe is for one from a rich or noble family; a Breitling suggests you like to pilot planes across the world. Watches are classified as "investment items" now. A 1994 Philippe recently sold for nearly PS 350, 000, while 1960s Rolexes have gone from 15, 000 to 30, 000 plus in a year. But, to some wealthy people, a watch is more than an investment. It's a valuable toy for... Options: A they have other devices to tell the time B they think watches are too expensive C they have little sense of time now D they prefer to wear an iPod on their wrists Answer: A they have other devices to tell the time Question:

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Work Your Mind Here's something to think about the next time you ask your teacher for help: struggling with schoolwork on your own can help you learn. According to a recent study, the more you struggle while you are learning new information, the better you can remember it later. This theory might surprise you. When teachers are presenting new information, they often give students lots of help. But a new study shows this may not be the best way to support learning. "Don't be too quick to get help when learning something new," education expert Manu Kapur told TFK. "Try to work on it yourself even if it means trying different ways." Kapur came up with the idea that struggling can lead to better learning. Then he tested it out on students in Singapore. He separated students into two groups. In the first group, students were asked to solve math problems with the teacher's help. In the second group, students were asked to solve the same problems by helping one another, instead of getting help from the teacher. With the teacher's help, students in the first group were able to find the correct answers. Students in the second group did not solve the problems correctly. But they did come up with a lot of good ideas. The students were then tested on what they had learned. The group without any help from a teacher scored much higher than the group who had help. Kapur said working to find the answers helped students understand the process, not just the solution. Kapur's advice for kids is to put a lot of effort into learning something new rather than going to your teacher for help. "Simply doing a little work or nothing at all won't work," says Kapur. "The struggle needs to be a genuine attempt to figure out or solve a problem in as many ways as possible." Options: A Getting the teacher's help. B Getting the student's help. C Grasping the learning course. D Receiving the final solution. Answer: C Grasping the learning course. Question:
