The iPad can be bought in more than 200 U.S. Apple stores from Apple. Many fans even waited overnight outside some Apple stores, hoping to be the first to get one. Dozens of the people were waiting before the door opened at 9:00 a.m. Hiro Kishimoto, a Japanese computer researcher who had a meeting in San Francisco, came as early as 5:00 a.m. He wanted to read books and magazines with the iPad. " It's much more comfortable than a laptop . Because the laptop is too heavy to carry all the time, when you are in the living rooms, maybe the iPad is the best one to use." He said.

Apple models that have both Wi Fi and 3G will be on sale in Australia, Canada, France, Germany, Italy, Spain, Swizland and the UK in late April.

Apple is trying to remake the tablet computer. The iPad doesn't support Adobe's Flash software that is used to watch many of the videos on the web. " It is short of a keyboard, a mouse, USB ports and mwlti-tasking." some researchers said. Options: A Y=299 B $299 C Y=499 D $499 Answer: D $499 Question:

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: American nutrition expert Professor Barry Popkin says that the number of overweight people in the world is now bigger than the number of people who don't have enough to eat. A billion people worldwide now weigh too much and the number of obese people is now more than 300 million. "Obese" means at least 15 kilos heavier than you should be. However, there are also 800 million people in the world who don't have enough to eat. Professor Popkin says that the number of hungry people is falling slowly but the number of overweight people is rising fast. The main reasons for this are: * People are doing less hard physical work * More people worldwide now eat too much fatty food * Too many people are driving cars instead of walking * People spend too much time in front of a television The United States has the highest rate of obesity in the developed world and Japan has the lowest. Professor Benjamin Senauer is absolutely certain of the reasons for this. "Japanese people are fit. They use public transport and walk," he said. "The average American drives to work and drives to supermarket. When he gets home, he sits on a couch in front of the TV and eats junk food." In Britain and many other European countries, there are three times as many obese people as there were 20 years ago. About two thirds of British adults are overweight or obese. "The effects of this are clear," said London doctor Elena Power. "We have more illnesses related to weight and fewer fit people. China used to be one of the slimmest nations in the world. However, Professor Wu Yangfeng from the Chinese Academy of Medical Sciences in Beijing recently estimated that 20 percent of the world's overweight people live in China. The Chinese government is especially worried about the increase in obesity among schoolchildren. "We have a serious problem," said Professor Wu. "It requires an improvement from everyone, or it will get worse. Options: A walking to work helps people keep fit.

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Amos Dudley, a 24-year-old boy who studies digital design at New Jersey University of Technology, felt ashamed about his teeth. But being a student, Dudley didn't have the money to get braces . So, he decided to 3-D print his own and marked down the DIY project in a recent blog post. His braces totaled less than $60, and after wearing them for 16 weeks, his teeth are also getting straighter. Months ago, he mentioned on his blog that he avoided smiling for a while because he was unhappy with his teeth. However, clear braces can get pricey, costing up to $8,000. But after studying some images of these expensive clear braces, something comes up on him--they looked like that one which can come from a 3-D printer. So he decided to hit up his school's 3-D printing equipment and scanned and printed models of his teeth. He then made non-harmful plastic molds around them to make 12 sets of braces. Dudley, who does not recommend attempting any of this at home said that he didn't ask a dentist for his project. But the student did get information from journal articles and textbooks. And though this was a perfectly friendly choice to buy braces. He didn't accept the project just to save money--he was also up for the challenge. "When I realized that I could do something that was a little bit special, while proving my skills as a designer and a maker, and fixing something that was making me self-conscious for actually free, I felt it was more than worth the risk." he said. Options: A The advice from the dentist. B The advice from his friends. C His major studies at university. D The possibility of making 3-D braces. Answer: D The possibility of making 3-D braces.
