According to the majority of Americans, women are every bit as capable of being good political leaders as men. The same can be said of their ability to dominate the corporate boardroom. And according to a new Pew Research Center survey on women and leadership, most Americans find women indistinguishable from men on key leadership traits such as intelligence and capacity for innovation, with many saying they’re stronger than men in terms of being passionate and organized leaders.

    So why, then, are women in short supply at the top of government and business in the United States? According to the public, at least, it’s not that they lack toughness, management talent or proper skill sets.

    It’s also not all about work-life balance. Although economic research and previous survey findings have shown that career interruptions related to motherhood may make it harder for women to advance in their careers and compete for top executive jobs, relatively few adults in the recent survey point to this as a key barrier for women seeking leadership roles. Only about one-in-five say women’s family responsibilities are a major reason why there aren’t more females in top leadership positions in business and politics.

    Instead, topping the list of reasons, about four-in-ten Americans point to a double standard for women seeking to climb to the highest levels of either politics or business, where they have to do more than their male counterparts to prove themselves. Similar shares say the electorate (选民) and corporate America are just not ready to put more women in top leadership positions.

    As a result, the public is divided about whether the imbalance in corporate America will change in the foreseeable future, even though women have made major advances in the workplace. While 53% believe men will continue to hold more top executive positions in business in the future, 44% say it’s only a matter of time before as many women are in top executive positions as men. Americans are less doubtful when it comes to politics: 73% expect to see a female president in their lifetime.

B。题目定位词为the primary factor和the recent survey，可以定位至第三、四段。第三段末尾指出，在最近的调查中，只有少数人认为家庭责任是阻碍女性担任高层领导的主要原因。随后第四段第一句指出，大约四成美国人指出，对于那些想要跻身政界或商界高层的女性来说，她们面临着双重标准，这使得她们必须做得比男性更多才能证明自己。另外还有相似比例的人认为，美国的选民和企业都还没有准备好让更多女性担任高层领导职位。这些都说明职场上存在对女性的偏见和不公，因此B项“性别偏见”最能概括调查结果，故选B。A、D两项在原文中未提及，故排除。C项出现在第三段最后一句，但只有五分之一（少数）的美国人认为家庭责任是限制女性在职业生涯中获得晋升的主要原因，所以C项错误。
