To Josephine Baker, Paris was her home long before it was fashionable to be an expatriate, and she remained in France during the Second World War as a performer and an intelligence agent for the Resistance.
没有选到D是因为思考的时候感觉D有两个问题，一方面：JB把巴黎视作家和她一直住在法国这两件事情，不懂为什么是同时要在法国被当做时尚之都之前这件事的修饰下；而不是巴黎被当做家和JB留在法国这两件事都是在对于JB而言的修饰下； 另一方面：D选项上来先说的是it，那如果需要把long before这半句放在句首的话，难道不是E更好吗？

In 1992 outlaw fishing boats began illegally harvesting lobsters from the territorial waters of the country of Belukia.  Soon after, the annual tonnage of lobster legally harvested in Belukian waters began declining; in 1996, despite there being no reduction in the level of legal lobster fishing activity, the local catch was 9,000 tons below pre-1992 levels.  It is therefore highly likely that the outlaw fishing boats harvested about 9,000 tons of lobster illegally that year.

Suriland cannot both export wheat and keep bread plentiful and affordable in Suriland. Accordingly, Suriland’s wheat farmers are required to sell their crop to the government, which pays them a dollar per bushel less than the price on the world market. Therefore, if the farmers could sell their wheat on the world market, they would make a dollar per bushel more, less any additional transportation and brokerage costs they would have to pay.

Which of the following, if true, most seriously weakens the argument?

Banker: My country’s laws require every bank to invest in its local community by lending money to local businesses, providing mortgages for local home purchases, and so forth. This is intended to revitalize impoverished local communities. But it is clear that the law will soon entirely cease to serve its intended purpose. An increasing number of banks incorporated in our country exist solely on the Internet and are not physically located in any specific community.

The banker’s argument is most vulnerable to criticism on which of the following grounds?

不太明白为什么internet bank不能达到法律的要求？即不能revitalize local community？题干哪里提到一定要physical locate才可以？
