input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Most people regard zoos as safe places for animals, where struggles such as difficulty finding food and avoiding predators don't exist. Without such problems, animals in zoos should live to a ripe old age. But that may not be true for the largest land animals on Earth. Scientists have known that elephants in zoos often develop diseases, joint problems and behavior changes. Sometimes, they even become unable to have babies. To learn more about how captivity affects elephants, a team of international scientists led by Mason, a biologist, compared the life spans of female elephants born in zoos with female elephants living outdoors in the wild. Zoos keep detailed records of all the animals in their care, documenting factors such as birth dates, illnesses, weight and death. These records made it possible for the researchers to analyze 40 years of data on 800 elephants in zoos. The team found that female elephants born in zoos lived an average of 16.9 years. Their wild counterparts who died of natural causes lived an average of 56 years----more than three times as long. Scientists don't yet know for sure why wild elephants seem to live so much better than their zoo-raised counterparts. Mason thinks stress and obesity may be to blame. Zoo elephants don't get the same kind of exercise as they do in the wild, and most are very fat. Elephant social lives are also much different in zoos than in the wild, where they live in large groups. Another finding from the study showed that elephants born in zoos were more likely to die earlier than elephants captured in the wild and brought to zoos. Mason suggests stress in the mothers in zoos might cause them to have babies that are less likely to survive. The study raises some questions about acquiring more elephants to keep in zoos. While some threatened and endangered species living in zoos reproduce successfully and keep healthy populations, that doesn't appear to be the case with elephants. Options: A develop health problems. B 1ive to a ripe old age. C are not afraid of predators. D have difficulty eating food. Answer: A develop health problems. Question:???
output answer: The text tells us that zoo elephants are different from other zoo animals because they _

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: A report brought back by most visitors to the US is how friendly, polite, and helpful most Americans were to them. To be fair, this observation is also frequently made of Canada and Canadians, and should best be considered North American. There are, of course, exceptions. Small-minded officials, rude waiters, and ill-mannered taxi drivers are hardly unknown in the US. Yet American's friendliness and helpfulness is an observation made so frequently that it deserves comment. For a long period of time and in many parts of the country, a traveler was a welcome break in an otherwise dull existence. Dullness and loneliness were common problems of the families who generally lived distant from one another. Strangers and travelers were welcome sources of distraction, and brought news of the outside world. The tough realities of the border also shaped this tradition of hospitality. Someone traveling alone, if hungry, injured, or ill, often had nowhere to turn except to the nearest settler agent. It was not a matter of choice for the traveler or only a charitable impulse on the part of the settlers. It reflected the hardship of daily life: if you didn't take in the stranger and take care of him, there was no one else who would. And someday, remember, you might be in the same situation. Today there are many charitable organizations which specialize in helping the exhausted traveler. Yet, the old tradition of hospitality to strangers is still very strong in the US, especially in the smaller cities and towns away from the busy tourist routes. "I was just traveling through, got talking with this American, and pretty soon he invited me home for dinner, amazing." Such observations reported by visitors to the US are not uncommon, but are not always understood properly. The casual friendliness of many Americans should be understood neither as superficial nor as artificial , but as the result of a historically developed cultural tradition. As is true of any developed society, in America a complex set of cultural signals and...
