Q: Write a multi-choice question for the following article, with the given choices and answer: Article: At first sight the planet Mars does not appear very welcoming to any kind of life. It has very little oxygen and water, the temperature at night is below 50 degrees and winds of 100 miles (161 kilometers)per hour cause severe dust storms. However, the surface of the planet seems to show that water flowed across it at some time in the past, and it is believed that there would be enough ice at the poles to cover the planet with water if it melted. Although there is no life on the Mars now, some scientists think there may have been some form of life a long time ago. At that time, the planet had active volcanoes ; the atmosphere was thicker and warmer; and there was water. In fact, in some ways the Mars may have been similar to the Earth, where life exists. Some people believe that the Mars could support life in the future if the right conditions were produced. The first step would be to warm the planet using certain gases which trap the Sun's heat in the planet's atmosphere. With warmth, water and carbon dioxide , simple plants could begin to grow. These plants could slowly make the Mars fit to live on. It is judged that the whole process might take between 100, 000 and 200, 000 years. In the meantime, people could begin to live on the planet in a special closed environment. They would provide a lot of useful information about conditions on Mars and the problems connected with living there. Options: A animals B mountains C dust D winds Answer: A animals Question:
A: According to the passage, the planet Mars has no _ on it.

Write a multi-choice question for the following article, with the given choices and answer: Article: Retail therapy has long been considered as a good way to let off stress. Now, US scientists have discovered not only does retail therapy exist,but that it could be caused by an individual's fear of sudden death. Researchers found materialistic people thought terrorism and war more stressful than others. Psychologists believe the rise of materialism around the world and its treatment effect on extreme stress might be a response to fear of death caused by acts of terrorism, disease and natural disasters. The scientists from Michigan State University said people with possession obsessions often have lower self-esteem than others so are more likely to shop as the result of severe psychological suffering. Ayalla Ruvio,a business professor studying people's shopping habits while rockets fell in Israel, said, "When the going gets tough, the materialistic people go shopping. This stress spending is likely to produce even greater stress and lower well-being. Essentially, materialism appears to make bad events even worse. Dr Ruvio led a two-part study of Israeli citizens living in a town that came under extreme rocket attacks for about six months in 2007. She compared 139 residents of the southern town with 170 from another town that was not under attack to see how their symptoms of post-traumatic stress and shopping habits varied. Dr Ruvio found that, when faced with a deadly threat, those who are highly materialistic suffered much higher levels of stress,while their tendency to shop was increased. Dr Ruvio said, "The relationship between materialism and stress may be more harmful than commonly thought." The second stage of their research surveyed 855 Americans about their materialistic nature and fear of death. They found shopping was used to relieve feelings of stress and anxiety about death but this was in response to fear of a variety of life-threatening events like car accidents, criminal attacks and natural disasters. Options: A They enjoy the special shopping culture. B The stresses they face are usually deadly. C They are in different situation in terms of war. D They are usually active participants for researchers. Answer: C They are in different situation in terms of war. Question:
