Q: Write a multi-choice question for the following article, with the given choices and answer: Article: For thousands of years comets have been a mystery to man. They travel across the sky very fast and have a bright "tail" of burning gas. The comet Tempel 1 has an orbit far outside the orbit of the furthest planet in our solar system, Pluto. It has been there for 4.6 billion years, 133 million kilometers from Earth. Last week a little American spacecraft crashed into Tempel 1. The spacecraft had a camera and it took a photograph of the comet every minute before it finally crashed into its surface. The space mission to Tempel 1 cost $335 million and was called Deep Impact. The spacecraft was travelling at 37,000 kilometers per hour when it hit the comet and the crash completely destroyed the spacecraft. But before it hit the comet, the spacecraft took some amazing photographs. The last one was a close-up picture which the spacecraft took just 3 seconds before it crashed into the comet. "Right now we have lost one spacecraft," said a delighted NASA engineer. Deep Impact was like a American Independence Day fireworks display. It took many years to plan and ended in an enormous explosion. The spacecraft which crashed into the comet was made of copper and was the size of a washing machine. It was dropped from a mothership into the path of the comet and the mothership then photographed the cloud of ice, dust and organic chemicals that rose from the surface of the comet after the crash. The crash completely destroyed the spacecraft but nothing really happened to the comet: experts believe that the crash slowed the comet down by no more than 1/10,000 of a millimeter a second.The aim of the mission was to study for the first time the _ of a comet.[:..] The mothership was 480 km from the explosion and observed the crash and the explosion with instruments for 800 seconds. Seven satellites, including the Hubble space telescope, watched the moment of drama, and over the next day and night about 50 telescopes on Earth were watching the distant comet. Options: A About 2,500 B About 3,500 C About 4,500 D About 5,500 Answer: B About 3,500 Question:
A: How many hours did it take for the spacecraft from the earth to touch the comet Tempel 1?

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: The industrial age has been the only period of human history in which most people's work has taken the form of jobs. The industrial age may now be coming to an end, and some of changes in work patterns which it brought may have to be reversed. This seems a discouraging thought. But, in fact, it could offer the prospect of a better future for work. Universal employment, as its history show, hasn't meant economic freedom. Employment became widespread when the enclosures of the 17th and 18th centuries made many people dependent on paid work by taking them away from the use of the land, and thus from the means to provide a living for themselves. Then the factory system destroyed the cottage industries and removed work from people's homes. Later, as transport improved, first by rail and then by road, people traveled longer distances to their place of employment until, eventually, many people's work lost all connection with their home lives and the places in which they lived. Meanwhile, employment put women at a disadvantage. In pre-industrial times, men and women had shared the productive work of the household and village community. Now it became customary for the husband to go out to paid employment, leaving the unpaid work of the home and family to his wife. Tax and benefit regulations still assume this norm today, and restrict more flexible sharing of work roles between sexes. It was not only women whose work status suffered. As employment became the dominant form of work, young people and old people were kept out -- a problem now, as more teenagers disappointed and annoyed at school and more retired people want to live active lives. All this may now have to change. The time has certainly come to switch some efforts and resources away from the utopian goal of creating jobs for all, to the urgent practical task of helping many people to manage without full-time jobs. Options: A paid work B unpaid work C taxes and benefits D land Answer: B unpaid work Question:
Answer: Before the enclosures of the 17thand 18th, people lived mainly on _ .

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: SHANGHAI - Health experts in Shanghai are calling for more protection for young children as the latest research shows about half of the youngsters are suffering from secondhand smoke. About 45 percent of children suffer passive smoking in families, 50 percent in public places, and almost 6 percent on public transportation, shows a research released by the Shanghai Children's Medical Center on Tuesday. "Not only adults but also children and newborn babies are at risk for the adverse effects of passive smoking," said Tang Jingyan, a doctor at the Shanghai Children's Medical Center. "Actually, those young children whose bodies are still growing and developing are more sensitive to the effects of secondhand smoke." Research has shown that children who are exposed to secondhand smoke will suffer from more colds, coughs and sore throats, and they are more likely to suffer from bronchitis, pneumonia and will have a higher risk of developing cancer. Doctors even suggested that children suffering passive smoking are more likely to have behavioral problems and may not develop mentally as quickly as their peers. Other research by the Shanghai Children's Medical Center has found that more than 80 percent of child patients in the center live in a smoke-filled household, where one or both parents smoke. "Though doctors have stressed the harm of passive smoking over and over, it is still hard to reach a totally 'smoke free' home," said a pediatrician named Zhang Yiwen, noting that parents are often tempted to smoke even though they have learned the harmful effects of secondhand smoke. China has 540 million people suffering from passive smoke, 180 million of them younger than 15.The age of smokers is also getting lower, earlier reports said. "There are more young smokers than before.You can see young people wearing a school uniform and carrying a schoolbag light a cigarette on the street.Some of them are even female students," said Jing Xingming, a professor of children's developmental behavior at the center.
