[Q]: Write a multi-choice question for the following article, with the given choices and answer: Article: As people in Beijing and northern China struggle with severe air pollution this winter,the toxic air is also making life hard for plants and even food crops of China. "in the last 50 years there has been a 1 6-fold increase in ozone pollution"in the Beijing area,said Hanqin Tian of Auburn University in Alabama,who studies the effects of China's pollution and climate change on plants. Ozone is particularly harmful to plants because it damages the pores on leaves,called stomata,which plants use to regulate how much water evaporates from the leaves.That,in turn,affectS how much water a plant must take up through its roots.Changes in water uptake by plants have been documented in other parts of the world,including the United States,as having major impacts on regional groundwater and surface water supplies. In studies of the long-term productivity of plants,Hanqin Tian and some of his colleagues show that ozone pollution,along with climate change,has been lowering plant productivity in China,which reduces the amount of carbon and other pollutants that the plants Can absorb to fight all the emissions from the burning offossil fuels. The worst effects on plants are likely to be in areas where the growing pollution problem is just fairly new, said Arthur Chappelka, also a plant researcher at Auburn University.Some plants are more resistant to pollutants than others,he said,and the plants that are living today in long-polluted urban areas are likely to be only those that are very pollution tolerant. Away from the cities, however, where crops are necded to feed China's yast population, the effeets of the growing pollution on crops is a significant concern. "In some ways it affects the crop production and food securiy of China,"said Hanqin Tian."Air quality is really important for human health, plants and ecosystem and sustainability." The problem is bound to get worse as China continues to develop economically, he said, and so he and other researchers continue to urge the Chinese government to take action to reduce...

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Florence Nightingale was born in a rich family. When she was young she took lessons in music and drawing, and read great books. She also traveled a great deal with her mother and father. As a child she felt that visiting sick people was both a duty and a pleasure. She enjoyed helping them. At last mind was made up. "I'm going to be a nurse," she decided. "Nursing isn't the right work for a lady," her father told her. "Then I will make it so," she smiled. And she went to learn nursing in Germany and France. When she returned to England, Florence started a nursing home for home. During the Crimean War in 1854 she went with a group of thirty eight nurses to the front hospitals. What they saw there was terrible. Dirt and death were everywhere to be seen -- and smelled. The officer there did not want any woman to tell him how to run a hospital, either. But the brave nurse went to work. Florence used her own money and some from friends to buy clothes, beds, medicine and food for the men. Her only pay was in smiles from the lips of dying soldiers. But they were more than enough for this kind woman. After she returned to England, she was honored for her services by Queen Victoria. But Florence said that her work had just begun. She raised money to build the Nightingale Home for Nurses in London. She also wrote a book on public health, which was printed in several countries. Florence Nightingale died at the age of ninety, still trying to serve others through her work as a nurse. Indeed, it is because of her that we honor nurses today. Options: A Her father's support. B Her desire to help the sick. C Her education in Germany and France. D Her knowledge from reading great books. Answer: B Her desire to help the sick. Question:

output: What made Florence make up her mind to become a nurse?

Whereas the northern hemisphere is in the middle of winter, Australians are baking in summer heat. It is not unusual to have Christmas Day well into the mid 30 degrees Celsius, or near 100 degrees Fahrenheit. A traditional meal includes a turkey dinner, with ham, and pork.

Problem: Write a multi-choice question for the following article, with the given choices and answer: Article: I live in Hollywood. You may think people in such an attractive, fun-filled place are happier than others. If so, you have some mistaken ideas about the nature of happiness. Many intelligent people still equate happiness with fun. The truth is that fun and happiness have little or nothing in common. Fun is what we experience during an act. Happiness is what we experience after an act. It is a deeper, more long-lasting emotion. Going to an amusement park or ball game, watching a movie or television, are fun activities that help us relax, temporarily forget our problems and maybe even laugh. But they do not bring happiness, because their positive effects end when the fun ends. I have often thought that if Hollywood stars have a role to play, it is to teach us that happiness has nothing to do with fun. These rich, beautiful individuals have constant access to exciting parties, fancy cars, expensive homes, everything that spells "happiness". But in memoir after memoir, celebrities reveal the unhappiness hidden beneath all their fun: depression, alcoholism, drug addiction, broken marriages, troubled children, and long-time loneliness. The way people hold on to the belief that a fun-filled, pain-free life equates happiness actually decreases their chances of ever attaining real happiness. If fun and pleasure are equated with happiness, then pain must be equated with unhappiness. But, in fact, the opposite is true: More times than not, things that lead to happiness involve some pain. As a result, many people avoid the very efforts that are the source of true happiness. They fear the pain inevitably brought by such things as marriage, raising children, professional achievement, religious commitment, charitable work and self-improvement. Options: A are the things we do before we find happiness B may help us relax and forget our problems sometimes C will lead us to the true happiness D could provide long-last positive effects Answer: B may help us relax and forget our problems sometimes Question:

A:
According to the passage, "fun activities" _ .
