Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: The Sieferts are the kind of environmentally conscious family who has solar panels atop their home. They use timers on their kids' showers and have planted drought-tolerant landscaping. But they feel kind of guilt. "I haven't thought about the pool as much as I probably should," said Annette Siefert. As California's drought worsens, swimming pools have become a target for those who think the classic backyard greens waste water. Some water districts have banned new pools from being filled and have limited how much water existing pools can use. But some of those agencies are walking back the rules as they make a surprising discovery: Pools aren't the water wasters some have made them out to be. Analyses by various water districts, along with scientific studies, conclude that pools and their surrounding landscapes use about the same amount of water as a lawn of the same size. Over time, pools might even use less water. With pool covers, experts say water evaporation can be cut by almost half, making pools significantly less wasteful than grass and about as efficient as drought-tolerant landscaping. Facing complaints over a recent ban on filling pools, the Santa Margarita Water District conducted its own water-use analysis. It found that pools require thousands of gallons of water to fill initially, but they use about 8,000 gallons less water than a traditional landscape after that. By the third year, the analysis found, the savings add up, and a pool's cumulative water use falls below that of a lawn. Water agencies such as the Los Angeles Department of Water and Power have come to similar conclusions. Armed with new information, Santa Margarita Water District officials will reconsider their ban next week. "We want to respect the people's rights to use their property. There are many families we know that have saved for pools," said Jonathan Volzke, spokesman for the 155,000-customer district. "But at the same time, the reality around us is that we're in the third year of a serious drought, and we don't know if...

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: A lot of people think Scotland is a part of England , but, as any Scotsman will tell you , it certainly is not. In fact, until the eighteenth century Scotland was an independent country, with a parliament of its own. The English had tried many times over many centuries to bring Scotland under their rule. They succeeded at last in 1707, and some Scots have never forgiven them. Scotland is now governed from London, but in some ways it is still a separate nation. It has its own capital city(Edinburgh),its own law, and its own stamps, it even has a language of its own, spoken now by only a few people in the islands. In some ways Southern Scotland is like England, with his good farmland and low green hills. Central and Northern (the Highlands) have high mountains and deep valleys, fast rivers and cold lakes. These days, of course, there are good roads and railways all through Scotland. Aberdeen, the northeast city where the oil from the North Sea comes to land, is especially easy to reach. But it can still be quite different to travel in the winter when the hills are covered with snow. It always takes a long time to visit the beautiful but far-off islands on the west coast. One reason why Scotland has stayed so different from England is the wildness of the land. It has always been difficult to get around there. Options: A which is spoken by all the Scots B which not many people speak now C which is almost the same as English language D which the English prevent from being spoken Answer: B which not many people speak now Question:

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: BEIJING -- After a night of wining and dining with 50 of China's richest people, Warren Buffet and Bill Gates told the journalists on Thursday that the biggest difference between eating with Chinese tycoons and Western ones was the food. "I was amazed last night, really, at how similar the questions and discussions and all that were to those in the dinners we had in the U.S.," said Mr. Buffett. Mr. Buffett and Mr. Gates, two of the best known Westerners here, announced in September, 2010 that they planned to invite 50 wealthy Chinese tycoons to dinner in Beijing to encourage philanthropy among China's new rich. On Thursday, the two men pronounced the dinner a great success, saying that two-thirds of those invited had shown up, and that more than half of them had offered their own ideas on how Chinese philanthropy should work. The guest list wasn't made public, but the Chinese news media reported that it included Jet Li, the movie star; Niu Gensheng, the founder of a Chinese dairy business; and Pan Shiyi and Zhang Xin, who control the SOHO China real estate empire. As with four earlier dinners held in the United States, Mr. Buffett and Mr. Gates said, no one at the Beijing event was asked to donate money or to promise to engage in charity. "Bill and I won't be calling anybody. What happens in China will depend on what the Chinese people feel about a project of this sort," said Mr. Buffett. China is widely reported to be second only to the United States in the number of dollar billionaires. Mr. Gates and Mr. Buffett said the nation was unique because its wealthy class had arisen almost wholly in the past 30 years, so the philanthropic practices established among European and American dynasties are new here, and open to change. The two said the dinner wasn't a long planned matter, but _ of a trip that Mr. Buffett had already scheduled to Guangdong and Hunan Provinces, where BYD Company, a maker of clean-energy automobiles, has factories. Mr. Buffett's company, Berkshire Hathaway, holds a 10% stake in the... Options: A A brief analysis of future philanthropy. B The development of Chinese philanthropy.
