OG12-81 求助大牛小牛各种牛~~~

81.        When demand for a factory's products is high, more
money is spent at the factory for safety precautions
and machinery maintenance than when demand is low.
Thus the average number of on-the-job accidents per
employee each month should be lower during periods
when demand is high than when demand is low and
less money is available for safety precautions and
machinery maintenance.

Which of the following, if true about a factory when
demand for its products is high, casts the most
serious doubt on the conclusion drawn above?

(B)        Its management hires new workers but lacks the
time to train them properly.

(0   Its employees are less likely to lose their jobs
than they are at other times.

(D)        Its management sponsors a monthly safety
award
                                    for each division in the factory.

(E)        Its old machinery is replaced with modern,
automated models.

这题选B，削弱的是average number of on-the-job accidents peremployee each month should be lower ，我懂了，可是我想选D，

我觉得它削弱了less money is available for safety precautions andmachinery maintenance.然后又因为这两部分是用and连接的，所以我认为既然B对，D就没理由不对，请教各位NN我究竟错在哪里呢？

D 有些无关，safety award并不等同于money spent at the factory for safety precautions
and machinery maintenance,也不能说明这个钱花的少了。

好比说

我花在吃糖多时，花的预防蛀牙上的钱多。所以呢吃糖多时我的蛀牙应该更少了，并且我在预防蛀牙上花的少了。那么D选项是说我每个月给我的牙又上了份保险，这是和预防牙齿的钱是没关系的，也不能影响我的蛀牙情况~~~

可以翻译成 能用的到的 意思吧~~

我也不知道我举的例子行不行，总之我感觉这个题的逻辑就像是由于害怕蛀牙我狂刷牙后来发现自己牙齿状况很好又不想像以前那样狂刷牙了一样

when demand is low [and less money is available for safety precautions and machinery maintenance.]

我觉得这后半句只是写得比较长而啰嗦，lzmm用颜色标出的[]这半句，感觉是对应题首的“more
money is spent at the factory for safety precautions
and machinery maintenance”而写的。

解题的关键是看问题： casts the most serious doubt on the conclusion.

conclusion是什么呢？——average number of on-the-job accidents per
employee each month should be lower...
        

那么对结论引发doubt的，就是使这个average number不降反升。

嗯  我刚看完答案也是这个感觉 ，觉得 GMAC太阴险了，故意弄个长句子在这干扰…
