input question: Write a multi-choice question for the following article: Article: The first day of school always goes wrong. For many students in the United States, however, this year it was even more so. It was all due to one extra school policy - they are now required to follow a new standardized dress code. According to the handbooks of all high schools in Allentown, Pennsylvania, students must wear short- or long-sleeve polo shirts and khaki or black pants. Skinny jeans, leggings and open-toe shoes are not allowed. Allentown schools are not alone. At Edgewater High School in Florida, shirts must have collars or sleeves, and pants must not sag and reach at least mid-thigh . No see-through shirts or T- shirts with references to sex on them are allowed. Overall, more than half of US public schools now enforce dress codes, according to the National Center for Education Statistics. About 57 percent of schools now have a "strict dress code", up from more than 47 percent a decade earlier, USA Today said. Among young people, there are mixed emotions. Some don't mind wearing similar clothes every day while others aren't happy. Despite dress codes in many school districts, some students still come to school - even on their first day - in skirts that are too short, necklines that are too low and sagging pants that don't stay up on their hips. But there are punishments. If they are out of dress code, students can be removed from the classroom until they fix the problem. In Florida, wearing sagging pants is illegal for youths according to a state law issued in 2011. Breaking the rule results in not being able to do after-school activities, and even being forbidden to attend class. Some US schools go further and require students to wear uniforms. Many say that they simplify their jobs, saving teachers from having to punish students for wearing skirts or shorts that are too short, for instance. They can also prevent feelings of competition and envy among students. "It takes away the daily fashion show and helps level the playing field a little bit with the haves and have-nots," longtime school...???

input question: Write a multi-choice question for the following article: Article: In 1800, only three percent of the world's population lived in cities. Only one city -- Beijing -- had a population of over a million. Most people lived in rural areas, and never saw a city in their lives. In 1900, just a hundred years later, roughly 150 million people lived in cities, and the world's ten largest cities all had populations exceeding one million. By 2000, the number of city dwellers exceeded three billion; and in 2008, the world's population crossed a tipping point -- more than half of the people on Earth lived in cities. By 2050, that could increase to over two-thirds. Clearly, humans have become an urban species. In the 19th and early 20th centuries, many people viewed cities negatively -- crowded, dirty environments full of disease and crime. They feared that as cities got bigger, living conditions would worsen. In recent decades, however, attitudes have changed. Many experts now think urbanization is good news, offering solutions to the problems of Earth's growing population. Harvard economist Edward Glaeser, author of The Victory of the Cir, is one such person. Glaeser argues that cities are very productive because "the absence of space between people" reduces the cost of transporting goods, people, and ideas. While the flow of goods has always been important to cities, what is most important today is the flow of ideas. Successful cities enable people to learn from each other easily, and attract and reward smart people with higher wages. Another urbanization supporter is environmentalist Stewart Brand. Brand believes cities help the environment because they allow haft of the world's population to live on about four percent of the land. This leaves more space for open country, such as farmland. City dwellers also have less impact per person on the environment than people in the countryside. Their roads, sewers, and power lines need fewer resources to build and operate. City apartments require less energy to heat, cool, and light. Most importantly, people in cities drive less so they...???

input question: Write a multi-choice question for the following article: Article: Smart phones that react to your moods and televisions that can tell it's you who's watching are in your future as Intel Corporation's top technology expert sets his sights on context-aware computing. Chief technology officer Justin Rattner showed how personal devices will one day offer advice. "How can we change the relationship so we think of these devices not as devices but as assistants or even companions?" he asked. Handheld devices could combine already common geographic location technology with data from microphones, cameras, heart and body monitors and even brain scans to offer their owners advice that today only a friend or relative could give. "Imagine a device that uses a variety of sensors to determine what you are doing at an instant, from being asleep in your bed to being out for a run with a friend, " Rattner said, "Future devices will constantly learn about who you are, how you live, work and play.'' Rattner also demonstrated a television remote control that figures out who is holding it based on how it is held, and then learns the viewer's entertainment preferences. As the world leader for decades in microchips for servers and desktop computers, Intel is hurrying to catch up in the profitable market for smart phones like Apple's iPhone and Research in Motion's Blackberry. Telephones with e-mail, global positioning and media players are pointing the way to a future where ever more functions are packed into ever smaller mobile devices. The smart phone industry, including technology giants like LG and Samsung, is likely to sell 270 million phones this year and grow 25 percent in 2011, according to market research company IDC. "I think you can expect to see features that support context-aware computing starting to appear in Intel products in the near future," Rattner said. But analysts say Intel faces an uphill battle getting its microchips into new phones as Nvidia, Marvell and Qualcomm have already made headway with cheap, lower-power processors based on designs by ARM Holdings.
