请教一道狒狒题

127. Anthropologists assert that cultures advance only when independence replaces dependence---that is, only when imposition by outsiders is replaced by initiative from within. In other words, the natives of a culture are the only ones who can move that culture forward. Non-natives may provide valuable advice, but any imposition of their views threatens independence and thus progress. If one looks at individual schools as separate cultures, therefore, the key to educational progress is obvious:

which one of the following best completes the passage?

A.       individual schools must be independent of outside imposition

B.        some schools require more independence than others, depending on the initiative of their staffs and students

C.        school systems officials must tailor their initiatives for change to each individual school in the system

D.       outsiders must be prevented from participation in schools’ efforts to advance

E.        the more independent a school is, the more educational progress it will make

请问为什么不选E啊？，或者是B也可以啊。                                                      答案是A 

谢谢！

B中的staff和students出线的没道理啊，题干中根本没有提到。通常此类题型，答案中有新元素出现的都为迷惑项。

E中the more...the more也没有讲到过，反而说Non-natives may provide valuable advice，是不是也可以理解为某个阶段内more dependent，more progress啊？

B，some schools require more independence than others, depending on the initiative of their staffs and students
E，the more independent a school is, the more educational progress it will make

均为无关选项。
