B为什么不对呢？1930年以后的酒店能承载更多的人，证明1930年以后的质量更好，不就说明1930年以前木工做的没有那么skill和care吗？

请问A选项和B选项应该怎么比较？划线外对时态好像也没用什么提示，我错选了B，难道是During recent times不太好？

这一题我选择了C,考察比较的话不能是those指代the environment and natural resource base吗?这样比较的语意也很合理啊，为什么一定要比较countries呢？

我想请教金栩竹老师： B：to obtain 这里是表示目的，还是表示将来？to do 不定式在gmat中的用法除了表目的还有什么用法？ C：having done ...protect.. 这里having done做主语是什么用法，怎么理解？对having done这个点非常困惑 E: Ving1 , ving2 , 谓语动词... 这里keeping 是修饰整句话吗，还是修饰前面ving1?

The passage suggests which of the following about merchants in the post-Civil War southern United States? Options: They sought to preserve pre-Civil War social conditions. Their numbers in the legislatures had been diminished. Their businesses had suffered from a loss of collateral. They were willing to make business arrangements with former slaves. Their profits had declined because planters defaulted on debts for supply advances. 提问问，战后商人做了什么。然后发现这题没有很明显的定位呀。然后我就梳理大概逻辑框架：园主发布一个关于借钱种地的法律，他们想通过从商人那里借钱来控制被解放的奴隶。他们意淫了很多美事。。。。。但是，没想到这法律跑偏了，毁了园主的美事。获得自由的劳动力不要打工，要自己干，他们直接从商人那里借钱去了。这法律实际上常提供了一个独立的劳动力系统。。。。。。 然后我觉选了E，

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？

The author of the passage mentions the "OH! NO!" system primarily in order to Options: indicate a way in which the United States industry has become more like the Japanese auto industry challenge a particular misconception about worker empowerment in the Japanese auto industry illustrate the kinds of problem-solving techniques encouraged by company unions in Japan suggest an effective way of minimizing production costs in auto manufacturing provide an example of the responsibilities assumed by a foreman in the Japanese auto industry 听老英的没懂。问题问“OH NO”的目的，文章中出现BECAUSE ON NO，说明后面是ON NO的原因，不看。然后看前面，看了三句明白了一个事情：日本领导资源少，任务重。然后觉得E好棒，然后错了。求思路

According to the passage, Newhouse's view of the social welfare efficiency of nonprofit hospitals differs from Weisbrod's view in that Newhouse contends that government already provides most of the services that communities need argues that for-profit hospitals are better at meeting actual community needs than are nonprofit hospitals argues that nonprofit hospitals are likely to spend more to provide services that the community requires than for-profit hospitals are likely to spend argues that nonprofit hospitals ought to expand the services they provide to meet the community's demands believes that the level of care provided by nonprofit hospitals is inappropriate, given the community's requirements 我选了A,我想N和W是对立的，所以W的想法”补充政府负担不了的公共服务“的反面，

请老师讲解下这个题的思路可以吗

The passage suggests which of the following about the managers mentioned in the highlighted text? They have generally been motivated to streamline hospital services as a result of direct intervention by hospital owners. They are more likely than managers of nonprofit hospitals to use unnecessary amounts of resources to provide services. Their most important self-acknowledged goal is to achieve maximum financial efficiency so that hospitals show a profit. Their decisions regarding services provided by their hospitals may not reflect hospital owners' priorities. They do not place a high priority on maximizing profits, despite their desire to achieve efficiency. 我D/E之间错选，没读出来这两个选项本质区别。。。
