68. (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

这个题是说UNION在考虑STRIKE AGAINST 公司A，公司C同时拥有公司A和B，UNION试图通过影响公司B的收入来影响公司C的决策从而达到目的。

E是无关选项（如果题目为MOST的话），因为这个事三个公司与一个UNION的事情，与其他的五官。

BCD本质上都是一样的，间接相关，A是直接相关。
