Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Cowboy or spaceman? A dilemma for a children's party, perhaps. But also a question for economists, argued Kenneth Boulding, a British economist, in an essay published in 1966. We have run our economies, he warned, like cowboys on the open grassland: taking and using the world's resources, confident that more lies over the horizon. But the Earth is less a grassland than a spaceship--a closed system, alone in space, carrying limited supplies. We need, said Boulding, an economics that takes seriously the idea of environmental limits. In the half century since his essay, a new movement has responded to his challenge. "Ecological economists", as they call themselves, want to revolutionise its aims and assumptions. What do they say--and will their ideas achieve lift-off? To its advocators, ecological economics is neither ecology nor economics, but a mix of both. Their starting point is to recognise that the human economy is part of the natural world. Our environment, they note, is both a source of resources and a sink for wastes. But it is ignored in conventional textbooks, where neat diagrams trace the flows between firms, households and the government as though nature did not exist. That is a mistake, say ecological economists. There are two ways our economies can grow, ecological economists point out: through technological change, or through more intensive use of resources. Only the former, they say, is worth having. They are suspicious of GDP, a crude measure which does not take account of resource exhaustion, unpaid work, and countless other factors. In its place they advocate moreholistic approaches, such as the Genuine Progress Indicator (GPI), a composite index that includes things like the cost of pollution, deforestation and car accidents. While GDP has kept growing, global GPI per person peaked in 1978: by destroying our environment we are making ourselves poorer, not richer. The solution, says Herman Daly, a former World Bank economist and eco-guru, is a "steady-state" economy, where the use of... Options: A Ecology and economics are not mixed together B Human economy isn't recognized as parts of nature C The environment has both resources and wastes D Diagrams connect firms, households and the government Answer: B Human economy isn't recognized as parts of nature Question:

According to ecological economists, what is the mistake existing in conventional textbooks?

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: How to improve our life? Many people think that they have to accept whatever life throws at them. They'll say, "This is my destiny .I cannot change it." Of course not! You don't have to suffer needlessly. Your life depends on you, not on any other external factor. I know a woman who says she just accepts what life gives her because she has done everything she can to improve it. Guess what her lifestyle is? She wakes up in the morning, goes to work, comes back home, relaxes, chats with people, watches TV, and then goes to sleep. Next day, the same routine cycle follows. Huh! Is this what she calls "doing her best"? She believes she has tried her best and just accepts it in her heart that this is the life that has been intended for her and that her luck can only change if God wills it. She hasn't realized that we have to do our share of making the effort to live the life of our dreams. Remember that you harvest what you sow. You have to get off the sofa, get your eyes off the TV screen, get your hands off the phone(unless it contributes to your success),and get your mind and body to work! Don't expect your luck to change, unless you do something about it. If something goes wrong, don't just regard it as a temporary setback; instead, learn your lesson, make the most of the situation, and do something to solve the problem. It's not enough to think positively; you also have to act positively. If someone's life is in trouble, do you just hope and pray that things will turn out fine? Of course not! You get to do anything you can to save the person. So it is with your own life. It is not enough to hope for the best, but you have to do your best. In other words, don't just stand(or sit)there, do something to improve your life. Options: A understand yourself B improve your life C believe in yourself D change your normal way Answer: B improve your life Question:???

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: Technology is making life easier for some dairy farmers.They use robotic systems to milk their cows.Cows are trained to follow a series of paths that lead to milking stations.Only one cow at a time can enter a station. Once inside,the cow is rewarded with food.As the cow eats,a robotic arm cleans and connects the animal to the milking machine.A few minutes later,milking is complete.The gate is opened,the cow is released and the next cow enters. The robotic systems are designed to operate 24 hours a day.The cows get to decide when they want to be milked.Cows are milked an average of about three times a day.Some are milked four to six times a day. The cows wear collars around their necks that identify them to the system.A computer keeps records on their eating and milking.A cow is released from the station if the computer decides it should not be milked. The automated system also measures the temperature and color of freshly produced milk.Milk is thrown away if it does not pass the tests. Professor Plaut believes the systems will appeal especially to the next generation of farmers.She means young people who are more interested in technology and less interested in working all the time on the farm.Still,she says the price of robotic milking systems will continue to limit their use. Doug and Tina Suhr have more than 100 cows on their family farm.Last year it became the fourth farm in southeast Minnesota to get a robotic milking system.A recent story in a local agricultural newspaper said the first robot cost 175 000 dollars.The second cost 150 000. Doug told AgriNews that wages that would have been paid for one employee in five years will pay for one robot.He says the increase in milk production reaches a high of more than six kilograms per cow per day. Options: A Letting robot milk your cow B Milking cows by hand C Improving the quality of milk D Drinking fresh milk every day Answer: A Letting robot milk your cow Question:
