请教og 11-9

9        Mayor: In each of the past five years, the city has cut school funding and each time school officials complained that the cuts would force them to reduce expenditures for essential services. But each time, only expenditures for nonessential services were actually reduced. So school officials can implement further cuts without reducing any expenditures for essential services.

Which of the following, if true, most strongly supports the mayor's conclusion?

(B)  Sufficient funds are currently available to allow the city's schools to provide some nonessential services.

(D) Few influential city admistrators support the funding of costly nonessential services in hte city's schools.

og解释 D The arguement is about possible cuts in essential services, not in nonessential services.

B 明白为什么对，但是不是很明白D为什么错。请教大侠指点迷津。

D说nonessential services are cost,而且几乎没有人支持。如果削减的话，应该是先削减nonessential services啊。这样不就是支持mayor's conclusion了吗？

别总执著于“削减开支”的问题上，考虑一下D选项是否可以作为产生结论的原因，如果可以，就不正确，如果不可以，就正确。

D选项说没人愿意花钱支持学校的那些没用的活动。

想想，这是造成削减开支的原因么？很显然，这有可能是一个原因。所以，这个原因的出现，造成了原来的原因被替代。从而削弱了结论，而不是支持结论推理的过程。
