Read the following article and select the best answer. Article: Most mornings, the line begins to form at dawn: scores of silent women with babies on their backs, buckets balanced on their heads, and in each hand a bright-blue plastic jug. On good days, they will wait less than an hour before a water tanker goes across the dirt path that serves as a road in Kesum Purbahari, a slum on the southern edge of New Delhi. On bad days, when there is no electricity for the pumps, the tankers don't come at all. "That water kills people," a young mother named Shoba said one recent Saturday morning, pointing to a row of pails filled with thick, caramel -colored liquid. "Whoever drinks it will die." The water was from a pipe shared by thousands of people in the poor neibourhood. Women often use it to wash clothes and bathe their children, but nobody is desperate enough to drink it. There is no standard for how much water a person needs each day, but experts usually put the minimum at fifty litres. The government of India promises (but rarely provides) forty. Most people drink two or three litres--less than it takes to wash a toilet. The rest is typically used for cooking and bathing. Americans consume between four hundred and six hundred litres of water each day, more than any other people on earth. Most Europeans use less than half that. The women of Kesum Purbahari each hoped to drag away a hundred litres that day--two or three buckets' worth. Shoba has a husband and five children, and that much water doesn't go far in a family of seven, particularly when the temperature reaches a hundred and ten degrees before noon. She often makes up the difference with bottled water, which costs more than water delivered any other way. Sometimes she just buys milk; it's cheaper. Like the poorest people everywhere, the people of New Delhi's slums spend a far greater percentage of their incomes on water than anyone lucky enough to live in a house connected to a system of pipes. Question: Sometimes the water tanker doesn't come because _ . - there is no electricity - the weather is bad - there is no water - people don't want the dirty water
there is no electricity

Read the following article and select the best answer. Article: Two Chinese farmers who became an overnight hit when their heart-rending version of a famous pop song appeared on the Internet took to the stage in front of thousands of fans in Shanghai last Saturday. Wang Xu, 44,and Liu Gang, 29, sang "In the Spring" alongside the song's star composer Wang Feng, in front of about 80,000 people at the Shanghai Stadium. The audience buzzed with excitement and let out deafening cheers, the moment as they were introduced on the stage and then when Liu started the first sentence of their parts of the song. The two migrant workers became stars after singing the tearjerker song during an evening drinking session in a 6-square-meter rented room in a late August evening. A friend recorded the performance on a cell phone and posted it on the Internet. "If someday I am dead, please bury me in the spring," they sing. Wang's penetrating chorus, delivered with his eyes closed, has moved thousands to tears. Wang and Liu consider the song a true portrait of lower-class groups like themselves. "With no credit card, no girlfriend, or a home with hot water, but only a guitar, I am singing happily, on streets, under bridges or in wild country, though nobody pays attention to the music," they sing. To support his wife and two sons, Wang came to Beijing in 2000 from the countryside and has worked as a boiler man, and street peddler, before becoming a medical warehouse keeper, with a monthly pay of around 1,500 yuan. Little is left after he pays 600 yuan for rent and buys food. Liu came to Beijing in 2002. "I wanted to try my luck in the big city, " he said. He had worked as a guard, roadside peddler, and porter, but never had a stable job. Street performing was his main income, even after he married and became a father three years ago. Wang and Liu are still uncertain where their fame will lead. Wang has started learning to use a computer. They even have a micro blog account to communicate with fans. Question: It can be inferred from the passage that _ . - migrant workers' conditions will be improved soon. - they will learn to write songs on computers. - a song showing people's real life and feelings is more likely to be accepted. - singers for migrant workers are more likely to become popular.
(Answer)
a song showing people's real life and feelings is more likely to be accepted.

"Where shall I put up?" he said; "I hope the town has made preparations." Then he saw the statue on the tall column. "I will put up there," he cried; "it is a fine position, with plenty of fresh air." So he flew down and settled just between the feet of the Happy Prince. "I have a golden bedroom," he said softly to himself as he looked round, and he prepared to go to sleep; but just as he was putting his head under his wing a large drop of water fell on him. "What a curious thing!" he cried; "there is not a single cloud in the sky, the stars are quite clear and bright, and yet it is raining. The climate in the north of Europe is really dreadful." Then another drop fell. "What is the use of a statue if it cannot keep the rain off?" he said; "I must look for a good chimney-pot," and he determined to fly away. But before he had opened his wings, a third drop fell, and he looked up, and saw--Ah! What did he see? The eyes of the Happy Prince were filled with tears, and tears were running down his golden cheeks. His face was so beautiful in the moonlight that the little Swallow was filled with pity. "Who are you?" he said. "I am the Happy Prince." "Why are you weeping then?" asked the Swallow, "you have quite wetted me." "When I was alive and had a human heart," answered the statue, "I did not know what tears were, for I lived in theprefix = st1 /PalaceofSans-Souci, where sorrow is not allowed to enter. In the daytime I played with my companions in the garden, and in the evening I led the dance in the Great Hall. Round the garden ran a very high wall, but I never cared to ask what lay beyond it, everything about me was so beautiful. People called me the Happy Prince, and happy indeed I was, if pleasure be happiness. So I lived, and so I died. And now that I am dead they have set me up here so high that I can see all the ugliness and all the misery of my city, and though my heart is made of lead yet I cannot...

Because he thought it was raining despite bright and clear stars.
