Q: Write a multi-choice question for the following article: Article: If you go to Ethiopia,you'll find a strange palm-like structure,which is called Warka Water.It gathers water from fog and condensation and is invented by an Italian firm. When Italian designer Arturo Vittori and Swiss architect Andreas Vogler first visited Ethiopia in 2012,they were shocked to see women and children forced to walk miles to access what,for them,had always been within easy reach,water. Only 34 percent of Ethiopians have access to a reliable water supply.Some travel for up to six hours a day to fetch some or,even worse,have to use pond water polluted by human waste, _ the spread of disease. Worldwide,about 768 million people--two and a half times the U.S.population--don't have access to safe drinking water.So just imagine if we could just pull water out of thin air?That's what Vittori and Vogler asked once they saw the severe problem and promised to take action.Their firm,Architecture and Vision,has since come up with Warka Water,a grand palm-like structure that may look like something you'd see in a modern art museum,but it's been designed to harvest water from the air. Warka Water,which is named after an Ethiopian fig tree,is composed of a 30-foot bamboo frame containing a fog-harvesting nylon net that can catch water easily,can be easily lowered for repairs and allow communities to measure the water level.Collecting water through condensation is hardly a new technique,but the creators of Warka Water say their tree-inspired design is more effective,maximizing surface and perfecting every angle to produce up to 26 gallons of drinkable water a day--enough for a family of seven. Western organizations have been working to provide clean water access in Africa for decades,so Warka Water joins a very long list of earlier attempts.So far,high-tech solutions,like the once promising Playpump,have failed,mostly due to high costs and maintenance issues. This is where Warka Water stands apart--a lower-tech solution that is easy to repair and far more affordable than digging wells in the rocky Ethiopian plateau.
A: Question: Warka Water is designed mainly to _ .Options:A gather clean water efficientlyB reduce water supply costsC simplify maintenanceD preserve water suppliesAnswer:A

Q: Write a multi-choice question for the following article: Article: Cleveland has won the distinction of being the worst city in the United States, according to a new survey. The city has high unemployment, terrible weather, heavy taxes, and ordinary sports teams, all of which have pushed it to the No. 1 position in the Forbes.com list. "Cleveland was the only city that fell in the bottom half of rankings in all nine categories. And it has been entitled with a less than endearing nickname: the Mistake by the lake," Forbes said on its website, The economic downturn hit cities across the United States last year particularly in the mid-west section of the country. Crime and unemployment secured the No. 2 spot for Stockton, which held the top position in last year's ranking. Memphis got third place thanks to its violent crime rate and the number of officials who are guilty, while the poor auto industry drove the Michigan cities of Detroit and Flint into the top five. "A lot of the cities that showed up on our list are going through hard times fight now, dealing with high unemployment, with declining producing bases. Many have experienced strong movement out of the city over the last 20 and 30 years." Despite its fine weather, Miami scored in the bottom 10 percent in commuting time, and violent crime which sent it into sixth place. "One of the biggest surprises is Miami. The good weather and no state income taxes _ some of the severe problems that Miami has related to crime as well as long commutes," Badenhausen added. Florida was followed in the poor ranking by St Louis, Buffalo, Canton, Ohio and Chicago, which has the country's highest sales tax at 10.25 percent. New York, the nation's biggest city, is rich in culture but its lengthy commuting time and high income taxes pushed it into 16th place.

Q: Write a multi-choice question for the following article: Article: People in several American states may be surprised to see cars on city streets without a driver. Experimental driverless vehicles now are legal in Florida, Nevada and California. They are pointing the way to a future that is not far down the road. The high-tech company Google has a number of self-driving cars, which had covered 480,000 kilometers by August. Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020. In September, California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state. " Today we're looking at science fiction becoming tomorrow's reality-the driverless car. " The technology for these cars includes cameras, radar and motion sensors. The systems have been improved through competitions sponsored by the U. S. government agency DARPA. Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races. Cars have become much more fuel-efficient, and new electronic features are' making Hondas safer, said Angie Nucci of Honda America. " A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes. " Other safety features include warning systems on the front and the sides of the cars. These systems help drivers , but don't replace them. Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer. "By taking out drivers, you also remove most risks of an accident," Kendall said. He said consumers, however, may be unwilling to lose control. "It may take them time to come to realize that the technology is indeed reliable, but it will have to prove itself first. " Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable. He said this will happen as the technology is improved. ks5u

Q: Write a multi-choice question for the following article: Article: As late as 1800, women's only place was in the home. The idea of woman in the business world was unthinkable. Men were certain that no woman could do a good job outside her home. This was such a widely accepted idea that when the well-known Bronte sisters began writing books in 1864, they had to sign their books with men's names instead. Teaching was the first profession open to women soon after 1800. But even that was not an easy profession for women to enter because most schools and colleges were open only to men. Oberlin College in Ohio was the first college in America to accept women. Hospital nursing became respectable work for women only after Nightingale became famous. Seeing that she was not only a nurse but also a rich and well-educated woman, people began to believe it was possible for women to nurse the sick and still be "ladies". Miss Nightingale opened England's first training school for nurse in 1860. The invention of the typewriter in 1867 helped to bring women out of the home and into the business world. By 1900, thousands of women were working at real jobs in schools, hospitals and offices in both England and America. Some women even managed to become doctors or lawyers. The idea that women could work in the business world had been accepted.
