Article: There's something rotten in Rio and the smell is coming from the huge stacks of rubbish pried up on sidewalks all over the city. Rio's street sweepers chose the carnival holiday to demand better salaries. Their wages start at roughly $400 a month. There could hardly be a better time for them to prove their importance. The streets were left a mess after hundreds of carnival parades and now, rubbish pries up in both poor and uptown neighbourhoods and in tourist areas like Ipanema or Copacabana beach. The president of Rio's rubbish collecting company has even appealed to the population to store rubbish at home whenever possible. He says 30% of the city's sweepers have gone on strike. Some of those who have been working have been threatened by the strike movement so now the police has been deployed alongside rubbish collectors to keep them sage as they go about their business. The strike has divided opinions in Rio. On social media, many support the sweepers' demands for better salaries. Others say they are opportunists and the situation is a big embarrassment to the city. But Brazil's culture of littering the streets doesn't help. A video that went viral online shows that even authorities have a problem with that. Rio's mayor, Eduardo Paes, is seen throwing what seemed to be the rest of an apple on the sidewalk--and now promised to impose himself a fine for his wrongdoing. His government recently created a programme to keep Rio's residents from littering the streets. Question: The reason why the police are involved is that _ Yes or no, is the answer "the police are required to protect some cleaners"?

Article: Li Denghai, with his muddy boots and tanned face, may not look like he is one of China's famous agricultural pioneers. But the 61-year-old man from Shandong Province has made scientific breakthroughs , which made great contributions to China's food security . His main work has been in achieving the higher output of corn production. Li, who holds the world record for the highest output of summer corn, once says, "Corn has a life; it sings and dances. If you listen clearly, it can speak to you." He started his research in 1969 when he was 20 and just dropped out of a high school. He then read an article which pointed that corn output per mu in the USA was six times higher than that in China. He was shocked and set out to work on just a small piece of land _ to see if he could increase the output. He often went to the field with a flashlight late at night, if he had been away during the day. By careful nurturing he managed to double the output. Li Denghai was awarded the "China Award for Significant Contribution to the Maize Industry" in 2005, and the same year the company named after his own name came into the market on the Shenzhen Stock Exchange. Li, however, is never happier than when he is in the middle of his cornfields. "I can forget my tiredness when talking to my corns," he says. Question: When Li Denghai began the study of corn, _ . Yes or no, is the answer "he was shocked that the corn output in China was so low"?

Article: The common Chinese greeting of "Ni chi le ma?" may soon be replaced by a new greeting: "Have you cleaned your plate?" Over the Spring Festival holiday there was a big effort to get people to curb their habit of ordering too much food in restaurants because a lot of that food ended up being wasted. Holiday eaters were urged to "clean their plates" and were asked to take leftover food home in "doggy bags." The impetus behind the campaign was the startling government statistic that over 200 billion yuan is spent every year on food that ends up in the garbage bin. And in the midst of all this waste, statistics show that 128 million people are living below the poverty line and going hungry. The "clean your plate" campaign is part of a worldwide effort to stop precious food from being wasted. The United Nations estimates that $1trillion (yes, that's a very big number) worth of food is wasted each year. Most of that is lost during food production and transportation, but a significant percentage is attributed to waste by consumers. The United Nations Environment Program (UNEP) has launched a campaign called "Think. Eat. Save." to make people aware of the problem. Chinese actress Fan Bingbing is an ambassador for UNEP and she encouraged people to upload pictures of their "clean plates" to show their support for the program. Thousands of people responded and demonstrated that they had a clear conscience to go along with their full stomachs. Xi Jinping, the incoming Chinese president, is also urging people to be less wasteful and he told Party members to cut back on extravagant holiday banquets and to be more careful when spending the people's money. For some, though, Xi Jinping's and Fan Bingbing's admonitions don't go far enough. Yuan Longping, an agricultural scientist, caused a stir by saying that wasting food should be treated as a crime. (Jail time for leftover chicken feet!?) If not a crime, wasting food is certainly a sin and it goes against what Xi Jinping calls, "the Chinese tradition of being diligent and... Question: Which statement is NOT TRUE according to the passage? Yes or no, is the answer "It's universally acknowledged that wasting food is a crime."?
