A选项反而加强了argument，因为这些star cluster并不会因为重力太大而collapse，所以是有可能为dim star的
B选项难在选项看不懂 preclude=排除，抽主干看：A cluster of stats preclude the existence (phenomena observed at M87 center)，表示如果中间是星星的话，那么就观察不到这个中心的其他天文现象（例如附近的物体快速转动 - 个人浅见），所以给了一个和前提矛盾的描述）
The numerical effect is obvious: there are fewer salmon in degraded regions than in pristine ones; however, habitat loss also has the potential to reduce genetic diversity.
The boycott shut. down much of the City's foodstuffs marketing for two weeks, "riveting public attention on the issue of food prices"
错选D，那个应该是socialist的部份，women动机并没有提到这点
错选B，题目问的是socialist的commitment，不是women
正确选项D定位到这段：
For others, cost-of-living or organizing was valuable insofar as it led women into the struggle for suffrage, and similarly, the suffrage struggle was valuable insofar as it moved United States society one step closer to socialism
又一次选错了..
避免过度控制，
B：any substance to be made subject to controls can actually cause environmental damage，如果造成环境污染的就控制，没过度，正确
D：all of any given pollutant that is to be controlled actually reaches the North Sea at present 要被控制的污染物现在已经到达北海，没到达也有可能造成污染，不涉及过度控制，排除
E：environmental damage already inflicted on the North Sea is reversible 环境污染无论可不可逆与是否过度控制无关，排除
B：Whereas Country Y is landlocked, Country X has a major seaport. 地形对于产量会有影响，但是题目并没有明说【哪一种地形对产量更好blabla】，相关性差
D：The crops that have always been grown in Country X are different from those that have always been grown in Country Y.两国种的农作物不相同，直接构成了使得产量变动的他因，相关性高
B：Whereas Country Y is landlocked, Country X has a major seaport. 地形对于产量会有影响，但是题目并没有明说【哪一种地形对产量更好blabla】，相关性差
