7. To be accepted as a member at the Brown Country Club, one must have a net worth of over ten million dollars and must not have any connections to the entertainment industry. Robert Chase, the publishing magnate, has a net worth of 5 billion dollars and chase has not financed any Hollywood movies, so [face=Times New Roman]he must be accepted as a member at the Brown Country Club. [/face]

The two portions in boldface play which of the following roles?

(A) The first is the part of evidence in support of this argument; the second is the conclusion that could not be drawn from all evidence that the argument contains.
(B) The first is the first-evidence that supports this argument; the second is the mainpoint that must be drawn from all evidence that the argument includes.
(C) The first is the one fact of two that argument includes; the second is the conclusion that could be drawn from this passage.
(D) The first is the background that is necessary for this argument; the second is the conclusion that is not drawn only from the first.
(E) The first is the cause that the argument includes; the second is the effect that can be drawn only from this cause.

解释一下A 和 D的区别， 好吗。 谢谢fyhllj！

个人意见 not financed any Hollywood movies不等于 not have any connections to the entertainment industry，而且文中并没有说，两个条件是充分的，只说是必要的，无论如何推不吹文中第二个画线的结论，所以c不对。
d肯定不对，但我解释不了，请高手来帮忙吧

我不是高手，只是发表一下自己的理解。希望讨论！
(A) The first is the part of evidence in support of this argument;
(D) The first is the background that is necessary for this argument;
在first，我也没多少疑问，只是觉得background算不上，bg应该是很泛的东西，如果说本文第一句话时bg还合适一些。necessary感觉刺眼：）本题考得就是（necessary）必要和充分条件

(A)the second is the conclusion that could not be drawn from all evidence that the argument contains.
(D)the second is the conclusion that is not drawn only from the first.
all evidence CF.only from the first
这样看D说了一句大实话，没什么意义。

评：本题D是个很成功的迷惑项；ETS（？出题人）比较仁慈，把correct item 放在了第一个。

对付这个迷惑项的办法：对充要条件有高度的敏感性，明白本题考什么。
