According to the passage, a foreman in a United States auto company differed from a foreman in a Japanese auto company in that the foreman in the United States would not have been a member of an auto workers' union have been unlikely to support the goals of company management have been able to control production processes to a large extent have experienced greater stress have experienced less conflict with workers 选A的原因是因为前面说了关于日本工会中：“most union officers were foremen or middle-level managers, ”，然后说美国工会“federal law prohibited foremen from joining or leading industrial unions” 我找到对吗？
