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．

参考答案A

解析:
定位：由题干关键词0bama和economic inequality定位到文章第一段第二句：Inequality isdangerous，he argued，not merely because it doesn’t look good to have a large gap between the richand the poor，but because inequality itseff destroys upward mobility，malting it harder for the poor toescape from poverty．
详解：事实细节题。定位句提到，奥巴马把不公平称为“我们这个时代决定性的挑战”，并指出不公平之所以危险是因为它破坏了社会阶层的提升，令贫困者难以摆脱贫困，故答案为A。
点睛：B“它是社会稳定的最大威胁”，本文主要探讨的是社会阶层的提升，而不是社会稳定性，可以排除；C“它是收入增长的头号敌人”，这是对原文的曲解，社会不公平影响的主要是穷人社会经济地位的上升，文章并没有提到不公平和收入增长的关系，可以排除；D“它是我们这个时代最恶毒的社会罪行”，原文并没有从道德角度进行阐述，可以排除。
