8. (34191-!-item-!-188;#058&007616)

Leaders of a miners' union on strike against Coalco are contemplating additional measures to pressure the company to accept the union's contract proposal.  The union leaders are considering as their principal new tactic a consumer boycott against Gasco gas stations, which are owned by Energy Incorporated, the same corporation that owns Coalco.

The answer to which of the following questions is LEAST directly revelant to the union leaders' consideration of whether attempting a boycott of Gasco will lead to acceptance of their contract proposal?

(A) Would revenue losses by Gasco seriously affect Energy Incorporated?
(B) Can current Gasco customers easily obtain gasoline elsewhere?
(C) Have other miners' unions won contracts similar to the one proposed by this union?
(D) Have other unions that have employed a similar tactic achieved their goals with it?
(E) Do other corporations that own coal companies also own gas stations?

答案是E 但是我认为该选C 请大家指教

原文大意：

因为——G加油站属于E,C也属于E

所以——抵制G就可以抵制C

提干关键是：抵制G，也就是说，答案中如果没有“抵制G”的成份存在就是least relevant。

答案C和D的意思均是：有没有其他union也用这种方法（抵制G）获得过胜利？很显然，如果这种方法曾经成功过，那么说明这个方法可行。也就不是无关的。

而答案E的意思是：其他拥有C的公司是不是也拥有加油站？没有提到“抵制G”的问题，无关。
