标题: AA128 挺难CRACK的

128. The following appeared as part of an article in a weekly newsmagazine.

“The country of Oleum can best solve the problem of its balance of
trade deficit
by further increasing the tax on its major import, crude oil. After Oleum increased the tax on imported crude oil four months ago, consumption of gasoline declined by 20 percent. Therefore, by imposing a second and significantly higher tax increase next year, Oleum will dramatically decrease its balance of trade deficit.”

这个og11的新题目挺难的，想不出来怎么crack，请大家出出主意。

4个月时间太短

他因导致短时间内的石油消费减少....consumption of gasoline 不等于importation, 只是将价格转嫁到消费者

可以用其他方法解决赤字,这个by imposing a second and significantly higher tax increase next year,不是必要条件;也不是充分条件.,因为还要考虑到国内的需求,工业是否在迅猛发展等等...

1.可能赤字的问题不在于进口太多,而是出口太少.

2.加税和消费量下降不一定有因果关系,可能别的原因引起消费量下降.

3.就算有关系,4个月前可以实现目的,不代表现在可以.
