input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Self-employed private physicians who charge a fee for each patient visit are the foundation of medical practice in the United States. Most physicians have a contract relationship with one or more hospitals in the community. They send their patients to this hospital, which usually charges patients according to the number of days they stay and the facilities(operating room, tests, medicines that they use). Some hospitals belong to a city, a state or, in the case of veteran's hospitals, a federal government agency. Others are operated by religious orders or other non-profit groups. Some medical doctors are on salary. Salaried physicians may work as hospital staff members, or residents, who are often still in training. They may teach in medical schools, be hired by corporations to care for their workers or work for the federal government's Public Health Service. Physicians are among the best paid professionals in the United States. In the 1980s, it was not uncommon for medical doctors to earn incomes of more than $ 100 000 a year. Specialists, particularly surgeons, might earn several times that amount. Physicians list many reasons why they deserve to be so well rewarded for their work. One reason is the long and expensive preparation required to become a physician in the United States. Most would be physicians first attend college for four years, which can cost nearly $ 20 000 a year at one of the best private institutions. Prospective physicians then attend medical school for four years. Tuition alone can exceed $ 10 000 a year. By the time they have obtained their medical degrees, many young physicians are deeply in debt. They still face three to five years of residency in a hospital, the first year as an apprentice physician. The hours are long and the pay is relatively low. Setting up a medical practice is expensive, too. Sometimes several physicians will decide to establish a group practice, so they can share the expense of maintaining an office and buying equipment. These physicians also take care of... Options: A About seven years. B Eight years. C Ten years. D About twelve years. Answer: D About twelve years. Question:

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Animals are natural resources that people have wasted all through our history. Animals have been killed for their fur and feathers, for food, for sport, and simply because they were in the way. Thousands of kinds of animals have disappeared from the world forever. Hundreds more are on the danger list today. About 170 kinds in the United States alone are considered in danger. Why should people care? Because we need animals. And because once they are gone, there will never be any more. Animals are more than just beautiful and interesting. They are more than just a source of food. Every animal has its place in the balance of nature . Destroying one kind of animal can create many problems. For example, when farmers killed large numbers of hawks , the farmers' stores of corn and grain were destroyed by rats and mice. Why? Because hawks eat rats and mice. With no hawks to keep down their numbers, the rats and mice multiplied quickly. Luckily, some people are working to help save the animals. Some groups raise money to let people know about the problem. And they try to get the governments to pass laws protecting animals in danger. Quite a few countries have passed laws. These laws forbid the killing of any animals or plants on the danger list. Slowly, the number of some animals in danger is growing. Options: A Hundreds of kinds of animals have disappeared forever. B Many kinds of animals have died out. C About 170 kinds of animals have disappeared forever. D All kinds of animals are in danger. Answer: B Many kinds of animals have died out. Question:

When it comes, people from around the world, including 5,000 in the small town today, watch this tongue-twisting small town for a sign from one groundhog that supposedly predicts when that years' spring will arrive. If it's a cloudy day outside when the groundhog _ from its cave, then spring will arrive early that year. However, if it is sunny outside, the groundhog will supposedly be scared by its own shadow, hiding underground for six more weeks of cold weather. Of course, Punxsutawney Phil's prediction is no more able to guarantee the extended forecast than your local weatherman. ABC News reports that an analysis by the National Climate Data Center found that Phil's predictions are more often wrong than right. Philis is also found to have made some unpleasant predictions. Ever since 1887, he has predicted 99 extended winters and just 16 early springs .Nine of the years' predictions were unavailable, according to ABC. The holiday began as a German tradition in 18th century and became even more of a cultural phenomenon after the 1993 film Groundhog Day starring Bill Murray. Punxsutawney Phil has become a celebrity in his own right. Each year, the fatter animal with long teeth is watched by millions as he emerges from a cave in the town he is named after. Phil has become so beloved by the town that he actually lives in the local library with his "wife" Phyllis. Taking inspiration from the hard state of Bill Murray's character in the classic film, Yahoo contributor Owen Rust says Groundhog Day is a good time to reflect on one's routines.
