According to the passage, Kerber argued that political leaders thought that the form of government adopted by the United States after the American Revolution depended on which of the following for its success?
这道题我选了B，我看的框架是：LK认为在美国革命后，republican motherhood理论导致了女性教育机会的激增，原因是...；第二段：对republican motherhood的介绍极大改变了编史。在LK之前，教育历史学家很少提及女人和女孩，但是TW是个例外。最后提出，历史学家对LK的republican motherhood理论的依靠阻碍了这些趋势的出现，使得对革命改变女性生存的程度难以界定。 我把握的点就是女性的教育机会，在我看的框架立马没有family，而且这个只提了一次，所以直接排除了CDE。我想问下老师这道题做题思路应该是怎样的，才能抓住family？

A prominent investor who holds a large stake in the Burton Tool Company has recently claimed that the company is mismanaged, citing as evidence the company's failure to slow production in response to a recent rise in its inventory of finished products.  It is doubtful whether an investor's sniping at management can ever be anything other than counterproductive, but in this case it is clearly not justified.  It is true that an increased inventory of finished products often indicates that production is outstripping demand, but in Burton's case it indicates no such thing.  Rather, the increase in inventory is entirely attributable to products that have already been assigned to orders received from customers.

The author of the passage would probably agree with which of the following statements about the SCNs?
