A、46% of them. B、47% of them. C、62% of them. D、66% of them. B录音提到，66％的受访者认为美国贫富矛盾“严重”和“非常严重”，比2009年的47％上升许多，问题是问2009年的比例值，所以B项是正

A new Pew Research shows that the cultural battle between rich and poor is as fierce as ever.
    [23] Fully 66% of respondents believe there are "strong" or "very strong" conflicts between rich and poor in the U.S. That’s way up from 47% in 2009.
    The rich-poor conflict now even outshines the conflicts over immigration. The poll found that 62% of respondents believed there was a strong conflict between immigrants and native-born Americans, less than the 66% for rich-poor.
    What’s more, Americans remain highly skeptical of the way the rich in America get rich. According-to the poll, 46% of respondents believe the wealthy got wealthy "because they were born with money or they knew the right people."
    [24] Only 43% of Americans believe that "hard work, ambition or educations" are the reasons the rich got rich.
    Of course, these questions could have been phrased more precisely. Getting rich through an inheritance is very different from getting rich by making the right connections and relationships in life. They should be separated as wealth causes.
    And the numbers are about the same as they were in 2009, meaning that while class-warfare may be at an all-time high, Americans’ actual perceptions of the rich haven’t changed much.
    Yet their opinions are still fairly negative, since more Americans believe the rich owe their fortunes to their parents or clubby social circles rather than hard work, ambition or education. This skeptical view is most pronounced among the young, or those between the ages of 18 and 34.
    Republicans believe in the "hard work" path more than Democrats. And men generally fall into the "hard work" camp more than women.
    The results highlight just how conflicted Americans are about the rich. Most studies show that more than two-thirds of today’s millionaires made it themselves, rather than from inheritance. [25] And clearly education and skills matter in making a fortune in the knowledge economy.
    Yet the polls suggest that for many Americans, the rich form a self-preserving "club" that’s largely closed to the rest of us whether it’s because of family background or exclusive networks.
    23. How many respondents believed rich-and-poor conflicts in the U.S. were strong in 2009?
    24. What makes the rich get rich according to 43% of respondents?
    25. What is the important factor for making a fortune in the knowledge economy?
