In the seventeenth-century Florentine textile industry, women were employed primarily in low paying, low-skill jobs. To explain this segregation of labor by gender, economists have relied on the useful theory of human capital. According to this theory, investment in human capital—the acquisition of difficult job-related skills—generally benefits individuals by making them eligible to engage in well-paid occupations. Women’s role as child bearers, however, results in interruptions in their participation in the job market (as compared with men’s) and thus reduces their opportunities to acquire training for highly skilled work. In addition, the human capital theory explains why there was a high concentration of women workers in certain low-skill jobs, such as weaving, but not in others, such as combing or carding, by positing that because of their primary responsibility in child rearing women took occupations that could be carried out in the home.There were, however, differences in pay scales that cannot be explained by the human capital theory. For example, male construction workers were paid significantly higher wages than female taffeta weavers. The wage difference between these two low-skill occupations stems from the segregation of labor by gender: because a limited number of occupations were open to women, there was a large supply of workers in their fields, and this "overcrowding" resulted in women receiving lower wages and men receiving higher wages.
The author of the passage would be most likely to describe the explanation provided by the human capital theory for the high concentration of women in certain occupations in the seventeenth-century Florentine textile industry as
来自一个网站的解析： 态度题：正确答案为(A)。问题要求评估作者的态度。做笔记后咱们已经分析评论道，文章对于理论的整体态度是正态度。定为原文有关作者态度的部分：原文第5行，作者characterizes the theory as useful，正态度。但是第二段说differences in pay scales cannot be explained by the human capital theory. 可以推断，作者对该理论整体持积极态度，但并非全盘支持。(B)(D) (E)都表示负态度，排除。(A)(B)都表达了双重态度，根据关联词，我们知道(A)强调正态度，(B)强调负态度，很明显作者认为human capital theory虽然存在瑕疵，但是是有用的。所以(A)更符合作者的态度。
正确理解问题的 high concentration of women 第一段原词 concentration出现 theory 可以解释 第二段 替换词 a large supply of workers in their fields, and this "overcrowding"=concentration 但是theory cannot explain
