看了解释还是存在不解。。
文章：
A Marxist sociologist has argued that racism stems from the class struggle that is unique to the capitalist system—that racial prejudice is generated by capitalists as a means of controlling workers. His thesis works relatively well when applied to discrimination against Blacks in the United States, but his definition of racial prejudice as “racially-based negative prejudgments against a group generally accepted as a race in any given region of ethnic competition,” can be interpreted as also including hostility toward such ethnic groups as the Chinese in California and the Jews in medieval Europe. However, since prejudice against these latter peoples was not inspired by capitalists, he has to reason that such antagonisms were not really based on race. He disposes thusly (albeit unconvincingly) of both the intolerance faced by Jews before the rise of capitalism and the early twentieth-century discrimination against Oriental people in California, which, inconveniently, was instigated by workers.

疑问：
最后一句.....，which, inconveniently, was instigated by workers.这个观点是马克思主义社会学家的承认的观点吗？还是不敢承认但是本质上正确的观点？
如果前者正确,那么
20. According to the passage, the Marxist sociologist’s chain of reasoning required
him to assert that prejudice toward Oriental people in California was
(A) directed primarily against the Chinese
(B) similar in origin to prejudice against the Jews
(C) understood by Oriental people as ethnic competition
(D) provoked by workers
(E) nonracial in character
除了E，D也正确吧？

如果后者正确,那么
17. The passage supplies information that would answer which of the following
questions?
(A) What accounts for the prejudice against the Jews in medieval Europe?
(B) What conditions caused the discrimination against Oriental people in
California in the early twentieth century?
instigated by workers —— Marxist sociologists
(C) Which groups are not in ethnic competition with each other in the United
States?
(D) What explanation did the Marxist sociologist give for the existence of racial
prejudice?
(E) What evidence did the Marxist sociologist provide to support his thesis?
除了D，B也应该正确吧？

20题我觉得这里找他的最原始的chain of reasoning
在倒数第二句not based on race.
他后面这句话是他自己为了解释上一个not based on race的解释。

17题并没有condition呀
直说 instigated by workers，你并不知道under what circumstance
