Q: Write a multi-choice question for the following article, with the given choices and answer: Article: WASHINGTON--Two-thirds of the world's polar bear population could be gone by 2050 if predictions of melting sea ice hold true, the US Geological Survey reported on Friday. The fate of polar bears could be even worse than that estimate, because sea ice in the Arctic might be disappearing faster than the available computer models predict, the geological survey said in a report aimed at determining whether the big white bear should be listed as a threatened species. "There is a definite link between changes in the sea ice and the welfare of polar bears," said Steve Amstrup, who led the research team. He says Arctic sea ice is already at the lowest this year and is expected to retreat farther this month. That means that polar bears--some 16,000 of them -- will disappear by 2050 from parts of the Arctic where sea ice is melting most rapidly, along the north coasts of Alaska and Russia, researchers said in a telephone briefing . Other polar bears could survive beyond that date but many of those could be gone by 2100, Amstrup said. By this century's end, the only polar bears left might live in the Canadian Arctic islands and along the west coast of Greenland. "It is likely to result in loss of approximately two-thirds of the world's current polar bear population by the mid 21st century," the report's executive summary said. "Because the observed trajectory of Arctic sea ice decline appears to be underestimated by currently available models, this assessment of future polar bear status may be conservative ." In January, the US Fish and Wildlife Service proposed listing the polar bear as a threatened species, noting polar bears depend on sea ice as a platform to hunt seals, their main food. Without enough sea ice, polar bears would be forced onto land, but they are poor hunters once they get out of the water and ice, the researchers said. The bears' disappearance would probably take place as young cubs failed to survive to adulthood and females were unable to reproduce successfully. Options: A help young polar bears to survive the cold winter B have large number of seals living in the oceans C make sure there is enough sea ice in the Arctic D provide chances for adult polar bears to reproduce Answer: C make sure there is enough sea ice in the Arctic Question:
A: The key to preventing polar bears dying out seems to _ .

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: TWENTY-FIVE years ago director Stephen Spielberg captured the hearts of Western audiences with his family classic.E.T.Now his Hong Kong director Stephen Chow is trying to do the same trick in China. Chow's latest movie CJ7(<<>> ),in cinemas now,is a heart-warming story about a poor migrant worker and his son.When a strange alien enters their lives,father and son learn a lesson about the value of family.Chow hopes his movie will help to make family films more popular in China. Family films have been the main part of the Hollywood market for the last 40 years.They have given audiences movies like E.T., Indiana Jones and Jurassic Park.However, there are few of these movies in China, where expensive history films are more popular. A family film is not simply a children's movie.It is a film that is not only suitable for children, but appeals to the whole family. According to Raymound Zhou,a famous film critic,these films are rare in China because "very few families go to the cinema together".Because of this,there is little demand for movies that appeal to the whole family. However, in the West,it is common for the family to sit down and watch a movie together.Tim Bridges, from London,says:"I love it at Christmas when I sit down and watch a movie with my family." All family films contain similar messages about being honest, remaining positive and learning there is more to life than money.According to the American movie reviewer,Dave Johnson, this is because "When parents watch a movie,they want their children to be learning good values". Just like when the alien in Spielberg's E.T.phones home to make contact with his family, Chow will hope Chinese audiences are tuned in and ready to receive his family movie message. Options: A Families in China should go to the cinema at Christmas. B It's good for children to watch family films. C Chinese families don't like family films. D The movie CJ7 has nothing in common with E.T. Answer: B It's good for children to watch family films. Question:
A: What is implied but not stated directly in the passage?

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: Age has its special advantages inprefix = st1 /America. And one of the more impressive of them is the senior citizen discount . Anyone who has reached a certain age-- in some cases as low as 55 -- is automatically entitled to plenty of price reductions at nearly every level of commercial life . Eligibility is determined not by one's need but by the date on one's birth certificate . Practically the discounts have become a routine part of many businesses-- as common as color1 televisions in motel rooms and free coffee on airliners . People with array hair often are given the discounts without even asking for them ; yet , millions of Americans above age 60 are healthy and solvent . Businesses that would never dare offer discounts to college students or anyone under 30 freely offer them to older Americans . The practice is acceptable because of the widespread belief that " elderly " and " needy " are synonymous . Perhaps that once was true , but today , to be sure , there is economic variety within the elderly , and most of them aren't poor . It is impossible to determine the effect of the discounts on individual companies . For many firms , they are a stimulus to income . But in other cases the discounts are given at the expense , directly or indirectly , of younger Americans . Moreover , they directly annoy some politicians and scholars who consider it a coming conflict between the generations . Generational tensions are being fueled by continuing debate over Social Security benefits , which mostly involves a transfer of resources from the young to the old . Employment is another point . Supported by laws and court decisions , more and more older Americans are refusing the retirement dinner in favor of staying on the job-- thereby lessening employment and promotion opportunities for younger workers . Far from a kind of charity they once were , senior citizen discounts have become a powerful economic privilege to a group with millions of members who don't need them . ... Options: A the elderly need humane help from society B businesses should do something for society in return C old people are entitled to special treatment for their contribution to society D the senior discounts can make up for the lack of the Social Security system Answer: A the elderly need humane help from society Question:
A:
The reason to gibe the senior citizen discount is that _
