Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: The prefix = st1 /USgovernment has announced plans to list polar bears as a threatened species because of concerns that the ice where they live is melting. But as the BBC's Owen Clegg reports, theUSplans are also important for other reasons. It's estimated that there are no more than twenty-five thousand polar bears living in the wild, and this number could go down by a large amount as the floating ice upon which the bears survive melt away. Now, without admitting the cause of this melt, the US Fish and Wildlife Services are reviewing the bear's living conditions. That action is being taken at all, and marks an important change for the Bush administration; for the first time, it may be forced to acknowledge a link between global warming and its effect on a species. Such a conclusion by an unwilling Bush administration could force far wider changes inWashington's policy towards the environment. This review only came about after a union of environmental groups brought a legal case against the government to take action. Environmentalists, like David Doniger, believe that by calling on the protections of the Endangered Species Act, theUSgovernment may finally be forced to cut back on its sending out greenhouse gases: "It is a very important thing today to have the Bush administration notice that global warming is threatening the existence of the polar bear. Now, it's up to the administration to do something to stop the global warming that's threatening the polar bear." ( David Doniger) The United States is the world's largest emitter of greenhouse gases which are blamed for trapping heat from the sun and changing the earth's climate. Since taking office in 2001, President Bush has refused to make the link with global warming, but the bad, serious situation of the polar bear may force that position to change. Options: A China. B Britain. C TheUnited States. D Not mentioned. Answer: C TheUnited States. Question:

A: Which country has been sending out the largest number of greenhouse gases according to the passage?

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: The surprising experiment I am about to describe proves that air is all around you and that it presses down upon you. Air pressure is a powerful force. When you swim underwater, you can feel water pushing on your body. The air all around you does the same. However, your body is so used to it that you do not notice this. The pressure is caused by a layer of air called the atmosphere. This layer surrounds the Earth, extending to about five kilometers above the Earth's surface. The following experiment is an easy one that you can do at home. But make sure that you are supervised , because you will need to use matches. Now for the experiment. What you need * hard-boiled egg without the shell * A bottle with a neck slightly smaller than the egg * A piece of paper * A match Method 1) Check that the egg will sit firmly on the neck of the bottle. 2) Tear the paper into pieces and put them into the bottle. 3) Light the paper by dropping a burning match into the bottle. 4) Quickly sit the egg on the neck of the bottle. Result Astonishingly, the egg will be sucked into the bottle. Your friends will be amazed when you show them the experiment. But be careful when you handle matches. Why it happened? As the paper burns, it needs oxygen and uses up the oxygen (air) in the bottle. The egg acts as a scale in the neck of the bottle, so no more air can get inside. This reduces the air pressure inside the bottle. The air pressure must equalize, so more air from outside must enter the bottle. The outside air presses against the egg, and then the egg is pushed into the bottle! This proves that air is all around and that it is pressing down on us. Options: A The bottle could break. B You need to light the paper with a match. C The egg needs to be shelled . D The egg has to be perfectly placed on the neck of the bottle. Answer: B You need to light the paper with a match. Question:

A: Why is there the need to take care when you are doing the experiment?

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: The 92-year-old, thin, calm and proud lady, who is fully dressed each morning by eight o'clock, even though she is nearly blind, moved to a nursing home today. Her husband of 70 years recently passed away, making the move necessary. After many hours of waiting patiently in the hall of the nursing home, she smiled sweetly when told her room was ready.

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: His eyes nearly in tears from the crush of fellow travelers at Guangzhou's train station, Hong Tao said things were much better on Sunday, after days of waiting for a train to his home in Hubei province. "I think it's fine today, and everything is going smoothly," the 28-year-old said. "I thought it would be really crowded but it has turned out to be OK." Chinese authorities say they expect 1.3 million people to travel out of Guangzhou's train station over the next few days, as they rush to get home by Wednesday, the eve of Lunar New Year. Hong's optimism may have been helped by the blue skies that emerged over Guangzhou on Sunday for the first time in a week. Last week, a rare winter storm paralyzed China's transportation system as millions tried to get home to celebrate the holiday -- the only chance for many migrant workers to see their families all year. China's state-run Xinhua news agency said Friday that 95 percent of rail traffic had "returned to normal." But Guangzhou's train station remained packed with a backlog of hundreds of thousands of travelers hoping to get home for the holiday. A young woman was stepped on in a stampede at the train station Friday, and later died of her injuries, according to Xinhua. Video of the situation on Friday showed crowds of people screaming, elbowing each other, in some cases sobbing and collapsing in the rush to get a slot (,) on a train. China Sunday announced it has organized over 300,000 People's Liberation Army forces to southern China in what it described as a "war on winter weather". The government also announced a $700 million plan to help farmers whose crops have been destroyed. Options: A Because the heavy snow stopped the passengers from leaving the station. B Because the passengers didn't hope to leave the station right now. C Because the passengers hoped to leave for their hometown. D Because the holiday was coming near. Answer: A Because the heavy snow stopped the passengers from leaving the station. Question:

A:
Why are there so many passengers in Guangzhou's train station?
