Question: Write a multi-choice question for the following article, with the given choices and answer: Article: Polar bears are born in dens on land and their mother stays with them for the whole winter without eating anything. The mother and the babies come out from the dens around March, _ from a long winter and must immediately go hunting to find food to stay alive. Now, the only hunting they know is to catch seals from floating ice in the open ocean. In March, polar bear mothers and babies have to swim from the land in Spitsbergen to the edge of the polar ice cap. Normally this is a short swim, since in March the polar ice cap is very close to the land, and the polar bears, and even the babies, are good swimmers. However, last year we saw that the polar ice cap had become smaller in size due to global warming. Swimming hundreds of miles, especially when they are hungry and have babies following them, is really hard, and many bears are dying because of starvation. The polar bear population in the Spitsbergen area was once threatened by hunters. In the 1970s, a ban on hunting was imposed and the polar bear population has been steadily increasing from just a few hundred to about 2,000 to 3,000. This was a great success story. However, now, because of global warming, the population is again in danger. If we do not stop making so much carbon dioxide, we will lose these beautiful animals forever. The polar bears are just one example of animals that have become endangered because of man's appetite for energy obtained by burning fossil fuels. All life on earth could be in danger unless we change our ways. What can we do? To reduce the amount of carbon dioxide in the air we must save and make energy without burning coal and oil. Instead, we can use the sun or the wind to generate electricity. We must also cut down on needless driving and turn off things that use electricity when we are not using them. In addition, we have to stop cutting down forests and start planting more trees. Options: A To get back to the ocean. B To catch seals for food. C To get to a colder place. D To teach their children how to swim. Answer: B To catch seals for food. Question:
Answer: Why do the bears swim to the edge of the polar ice cap?

[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: Plants may not have eyes and ears,but they can recognize their siblings ,and researchers at the University of Delaware have discovered how.The ID system lies in the roots and the chemical signals they secrete . Canadian researchers published that sea rocket,a common seashore plant,can recognize its siblings.Susan Dudley observed that when siblings are grown next to each other in the soil,they "play nice" and don't send out more roots to compete.However,the moment one of the plants is thrown in with strangers,it begins competing with them by rapidly growing more roots to take up the water and mineral nutrients in the soil. After reading Dudley's study,Bais decided to find the method behind the sibling recognition.Working in his laboratory,Bais and his doctoral student Meredith Biedrzycki set up a study with wild populations of Arabidopsis thaliana.In a series of experiments,young seedlings were exposed to liquid media containing the root secretions from siblings,from strangers,or only their own secretions.The length of the longest lateral root was measured.The exposure of plants to the root secretions of strangers induced greater lateral root formation than exposure of plants to sibling secretions.Strangers planted next to each other are often shorter,because so much of their energy is directed at root growth.Because siblings aren't competing against each other,their roots are often much shallower . Biedrzycki did the _ laboratory research,observing more than 3,000 plants involved in the study every day for seven continuous days and documenting the root patterns."Arabidopsis roots are nearly translucent when they are young and were also twisted when I removed them from plates,"Biedrzycki notes."This manuscript is very important for my research since the focus of my thesis project is understanding the biochemical ways behind root secretions." The research also may have implications for the home gardener."Often we'll put plants in the ground next to each other and when they don't do well,we blame the... Options: A A Great Biology Researcher B Plants Recognize Their Siblings C Plants' Roots and Secretions D A Research on Plants Answer: B Plants Recognize Their Siblings Question:

[A]: Which of the following would be the best title for this passage?

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: LOS ANGELES--The advice offered from any other 82-year-olds might have made young people yawn and roll their eyes. But when former South African President Nelson Mandela advised two dozenprefix = st1 /Los Angelesto take education seriously, his audience was listening. The famed old man said to the young people that if they expected to improve the lives of others in the future, they must work at improving their own lives now. "Education is one of the most important weapons you have," Mandela advised, "it will place you in a far better position to serve yourself and your community." "The point is, he was young once and rebellious once and he kept his dream alive, just as you each have dreams." ExplainedSouth Africa's ambassador to theUnited States, Sheita Sisulu, as she introduced Mandela to the young crowd. Asked for specific advice about changing society by 21-year-old Ahmed Younis, Mandela suggested that somehow helping arouse more American interest in foreign affairs might be a start. "There is an impression that Americans, in general, have not followed international developments properly," Mandela said, "I'm not making that statement myself, but there are serious political analysts who say Americans are not well informed as to what has happened in the world." 22-year-old Omari Trice said Mandela left him full of passion. "He's a person who set the tone for an entire nation." said Trice. "You go away feeling you need to be Superman in order to get things done." Trice said. Options: A are willing to accept the advice from world-famous leaders B usually think that advice from old people is not worth considering C have a good understanding of the old D have no intention to improve the lives of others Answer: B usually think that advice from old people is not worth considering Question:
