Both Fuchs and Sanborn have suggested that the effect of discrimination by consumers on the earnings of self-employed women may be greater than the effect of
Line either government or private employer discrimination on the earnings of women employees. To test this hypothesis, Brown selected a large sample of White male and female workers from the 1970 Census and divided them into three categories: private employees, government employees, and self-employed. Brown's results suggest that men and women are not treated the same by employers and consumers. For men, self-employment is the highest earnings category, with private employment next, and government lowest. For women, this order is reversed. One can infer from Brown's results that consumers discriminate against self-employed women. In addition, self-employed women may have more difficulty than men in getting good employees and may encounter discrimination from suppliers and from financial institutions.

8. A study of the practices of financial institutions that revealed no discrimination against self-employed women would tend to contradict which of the following?
(A) Some tentative results of Fuchs's study
(B) Some explicit results of Brown's study
(C) A suggestion made by the author
(D) Fuchs's hypothesis
(E) Sanborn's hypothesis


答案选C啊亲....为啥啊为啥不选B？？？作者哪里有给过建议啦？？求解答啊求解答....

When a molten metal or metallic alloy is cooled to a solid, a crystalline structure is formed that depends on the particular alloy composition. In contrast, molten nonmetallic glass-forming materials, when cooled, do not assume a crystalline structure, but instead retain a structure somewhat like that of the liquid--an amorphous structure. At room temperature, the natural long-term tendency for both types of materials is to assume the crystalline structure. The difference between the two is in the kinetics or rate of formation of the crystalline structure, which is controlled by factors such as the nature of the chemical bonding and the ease with which atoms move relative to each other. Thus, in metals, the kinetics favors rapid formation of a crystal line structure, whereas in nonmetallic glasses the rate of formation is so slow that almost any cooling rate is sufficient to result in an amorphous structure.

11. The author implies that the rate at which the molten
materials discussed in the passage are cooled is a
determinant of the
(A) chemical composition of the resulting solids
(B) strength of the chemical bonds that are formed
(C) kinetics of the materials' crystalline structure
(D) structure the materials assume
(E) stability of the materials' crystalline structure

12. It can be inferred from the passage that, theoretically, molten nonmetallic glasses assume a crystalline structure rather than an amorphous structure only if they are cooled
(A) very evenly, regardless of the rate
(B) rapidly, followed by gentle heating
(C) extremely slowly
(D) to room temperature （E ）  to extremely low temperatures
第一题选D 第二题选C  真心不懂...第十一题文中哪里有提到cooling rate的事啊？？？还有12题文中也没有提过啊，只说常温下最后会趋向晶体结构啊...

One can infer from Brown's results
所以不能选B的 explicit

3# lizsays 你是说one can infer....就相当于是作者的suggestion了？？？

第一段阅读支持三楼的回答，one can infer。。。就是指作者从前文得出的观点。
第二段阅读的11题估计是文段的问题，这是老题改的，原文在“...result in an amorphous structure.”后还有一句是"For glassy metals to be formed, the molten metal must be cooled extremely rapidly so that crystallization is suppressed."加上这一句会发现，cooling rate快则molten metal变crystalline structure，cooling rate慢则molten metal变amorphous structure，所以才选D；
12题根据题干中的"molten nonmetallic glasses "定位在"whereas in nonmetallic glasses the rate of formation is so slow that almost any cooling rate is sufficient to result in an amorphous structure"一句，既然任何cooling rate都会导致amorphous structure，那么理论上要导致crystalline structure 就只有对“任何cooling rate”取非了，即“不去进行cooling”，C最合适。

第一个，one can infer，就是说“我们可以从中推测出....”，就是代表作者的观点，翻译成中文就好说了。
第二个（1）同问，不明白
      （2）原文是，at room temperature和natural long-term tendency，一共两个条件，C符合一个，所以对了，我估计你错选D了，一个很贱的选项，他的意思是降低到room temperature，而不是原文中的在room temperature中进行
