user: Question: Read the following article and select the best answer. Article: The quality of drinking water in Shanghai will meet European Union standard by 2010 and, a decade later, citizens in Shanghai will drink the best water in the world. These were the goals set out by the Shanghai Water Authority. With the city's population expected to increase only slightly and the economy to boom by 2020, Chen Yin, an official in the water authority, said Shanghai's water consumption will not increase from its present amount. Zhang Yue, director of the Urban Construction Division under the Ministry of Construction, said, "Shanghai is the first city in the country to publicize these ambitions. They will not be easy to achieve." He said water saving will help keep the sustainable development of China's economy. Saving one cubic meter of water means saving the city's infrastructure costs by 10,000 Yuan. Last year, Shanghai saved 300 million cubic meters of water either from readjustment of industrial structure or the employment of new technology. "The aim is to arouse public awareness of the seriousness of water shortages," Chen said. "The abundant surface water and amount of rain of the city are so misleading that they result in improper use of water." Shanghai lacks drinkable water. The Huangpu River, which supplies 80 percent of the city's drinkable water, is nearing exhaustion. The city, therefore, has been exploring new sources from the Yangtze River and growing forests along it to conserve quality water. Besides penning regulations, the authority is popularizing technology among the public to efficiently cut the amount of water used. At present, the city has 600,000 family toilets, each using 13 liters of water per flush. These are to be renovated to use only 9 liters of water per flush. The authority is renovating the first 200 toilets for households - at a cost of Yuan each. In three years, all the toilets will be renovated, which saves the city nearly 15 million Yuan every year in water conservation. Another task the city is engaged in is the treatment of sewage to improve the water... Question: We can infer from the passage that  _  . - not everyone today in Shanghai is aware of water shortage - citizens today in Shanghai drink the best quality of water in the world - the boom of economy will need a larger amount of water in the future - all the family toilets will be renovated to save water within 3 years
Answer: not everyone today in Shanghai is aware of water shortage

Question: Read the following article and select the best answer. Article: A study published in September suggests there is a surprising way to get people to avoid unhealthy foods: change their memories. Scientist Elizabeth Loftus of the University of California at Irvine asked volunteers to answer some questions on their personalities and food experiences. "One week later," Loftus says, "we told those people we'd fed their answers into our smart computer and it came up with an account of their early childhood experiences." Some accounts included one key additional detail. "You got sick after eating strawberry ice-cream." The researchers then changed this detail into a manufactured   memory through leading questions --- Who were you with? How did you feel? By the end of the study, up to 41% of those given a false memory believed strawberry ice-cream once made them sick, and many said they'd avoid eating it. When Loftus published her findings, she started getting calls from people begging her to make them remember hating chocolate or French fries. Unfortunately, it's not that easy. False memories appear to work only for foods you don't eat on a regular basis. But most importantly, it is likely that false memories can be implanted   only in people who are unaware of the mental control. And lying to a patient is immoral , even if a doctor believes it's for the patient's benefit. Loftus says there's nothing to stop parents from trying it with their overweight children. "I say, wake up --- parents have been lying about Father Christmas for years, and nobody seems to mind. If they can prevent diseases caused by fatness and all the other problems that come with that, you might think that's more moral lie. Decide that for yourself." Question: What is the biggest concern with the method? - Who it is best for - When it is effective. - How it should be used. - Whether it is moral.
Answer: Whether it is moral.
