What do some experts say about doctors' involvement in medical cost analysis?

A．It may add to doctors' already heavy workloads．
B．It will help to save money for society as a whole．
C．It results from society's failure to tackle the problem．
D．It raises doctors' awareness of their social responsibilities．

参考答案C

解析:
定位：由题干关键词experts和medical cost analysis定位到文章最后一段：Still，some analysts say that there’s a role for doctors to play in cost analysis because not many others are doing So．“In some ways．”said Dr．Daniel Sulmasy．it represents a failure of wider society to take up the issue．’’
详解：推理判断题。最后一段首句指出，尽管医生兼任医药成本监察员的职责并不合适，但又不得不为之，因为很少有其他群体能做到，而作者更进一步引用丹尼尔·赛尔马西医生的话指出，整个社会没能成功处理这一问题，故答案为C。
点睛：A“它可能增加医生本已沉重的负担”，医学专家并没有就医生的负担轻重进行讨论，可以排除；B“它可以帮助整个社会节省经费”，专家们并没有提到这一点，可以排除；D.“它提升了医生的社会责任意识”，这种说法完全偏离了本文的中心思想，可以排除。

Questionsare based on the following passage．
Economic inequality is the "defining challenge of our time," President Barack Obama declared in a speech last month to the Center for American Progress．Inequality is dangerous, he argued, not merely because it doesn't look good to have a large gap between the rich and the poor, but because inequality itself destroys upward mobility, making it harder for the poor to escape from poverty．"Increased inequality and decreasing mobility pose a fundamental threat to the American Dream," he said．Obama is only the most prominent public figure to declare inequality Public Enemy No．1 and the greatest threat to reducing poverty in America．A number of prominent economists have also argued that it's harder for the poor to climb the economic ladder today because the rungs (横档 ) in that ladder have grown farther apart．
For all the new attention devoted to the 1 percent, a new damset from the Equality of Opportunity Project at Harvard and Berkeley suggests that, if we care about upward mobility overall, we're vastly exaggerating the dangers of the rich —poor gap．Inequality itself is not a particularly strong predictor of economic mobility, as sociologist Scott Winship noted in a recent article based on his analysis of this data．So what factors, at the community level, do predict if poor children will move up the economic ladder as adtdts? what explains, for instance, why the Salt Lake City metro area is one of the 100 largest metropolitan areas most likely to lift the fortunes of the poor and the Atlanta metro area is one of the least likely?
Harvard economist Raj Cherty has pointed to economic and racial segregation, community density,the size of a community's middle class, the quality of schools, commtmity religiosity, and family structure, which he calls the "single strongest correlate of upward mobility．" Chetty finds that communities like Salt Lake City, with high levels of two-parent families and religiosity, are much more likely to see poor children get ahead than communities like Atlanta, with high levels of racial and economic segregation．Chetty has not yet issued a comprehensive analysis of the relative predictive power of each of these factors．Based on my analyses of the data．of the factors that Chetty has highlighted, the following three seem to be most predictive of upward mobility in a given community:
1．Per-capita (人均) income growth
2．Prevalence of single mothers ( where correlation is strong, but negative)
3．Per-capita local government spending In other words, communities with high levels of per-capita income growth, high percentages of two-parent families, and high local government spending-which may stand for good schools-are the most likely to help poor children relive Horatio Alger's rags-to-riches story．
How does Obama view economic inequality?

A．It is the biggest obstacle to social mobility．
B．It is the greatest threat to social stability．
C．It is the No．1 enemy of income growth．
D．It is the most malicious social evil of our time．
