Ques: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: Rio's street cleaners go on strike to Yes or no, is the answer "ask for higher salaries"?

Ques:Article: Milan, the second largest city of Italy, has won an undesirable world record. Of the 54 big cities studied by the World Health Organization and the United Nations, Milan is considered to have the worst air pollution. According to these two10-year studies, the level of air pollution in Milan is twice as high as the levels in Paris and Beijing and three times those in Tokyo and London, and four times that in New York. The reason for Milan's bad pollution, to some experts, is that the city lies in a valley that holds back the poisonous gases. Though Milan has taken some measures to lower the level of pollution, the situation is still worrying. People joke to each other, "If you are traveling to Milan, be sure to bring your gas mask." In order to reduce the use of private cars, in 1979, the government in Milan began an interesting experiment: passengers in the city buses did not have to pay for their tickets. Question: Which of the following statements is NOT mentioned in the text? Yes or no, is the answer "Milan's air is considered to be worst polluted in Europe."?

Ans:No

Ques:Article: The National Gallery of Art in Washington, D.C., is one of the world's greatest art museums. Millions of people have entered its doors to see paintings by the world's fine artists. But if these priceless masterpieces are to be preserved, the Gallery must protect them carefully. The Gallery's 135-man guard force has successfully prevented them from being stolen, but protecting the paintings from nature is a greater problem. In past times, the owners of paintings did not protect them from damaging changes in humidity and temperature. As a result, the life of these paintings were shortened. In the National Gallery, however, humidity and temperature are carefully controlled. The building is air-conditioned in summer and heated in winter. The air-conditioning and heating system are so important to the life of the painting that the Gallery has two of each system. If one should fail, the extra one can take over. Light is another enemy of paintings. Ultraviolet rays in light cause paintings to fade . Long ago, paintings often hung in dark churches and palaces. A coat of varnish was a protection from the weak light. But when museums took over the care of many paintings, they were often hung in brighter light than before. Soon they were in danger of fading. The damaging effects of light were increased when the museums removed the varnish coating, yellowed with age. To protect its paintings, the National Gallery put a special kind of glass in its skylights. This glass allows visible lights to enter the building but it keeps out harmful ultraviolet rays. The Gallery has also developed new and better varnishes which help to keep paintings from fading. Thanks to these new _ , many of the world's greatest paintings are being well protected for future generations to enjoy. Question: From the text we can infer that _ . Yes or no, is the answer "the care of the world's greatest paintings is both a big responsibility and a great challenge"?

No
