用helr的因果逻辑晕晕的，哪一部分是前提 哪一部分是结论，傻傻分不清楚，求Helr/NN

同求问第一题，疑惑的地方是这一题的推理模式分类（Helr的），这一题和prep 08(72-125)里面的78题几乎是一模一样的原文。可是为什么这一题是因果推理，而78那一题是方案推理呀？（如下）

To improve the long-term savings rate of the citizens of Levaska, the country's legislature decided to implement a plan that allows investors to save up to $1,000 per year in special accounts without paying taxes on the interest earned unless withdrawals are made before the investor reaches age sixty-five.  Withdrawals from these accounts prior to age sixty-five would result in the investor's having to pay taxes on all the accumulated interest at the time of withdrawal.

Which of the following, if true, most strongly supports the prediction that the legislature's plan will have its intended effect?

Helr：该论证中显然涉及到了一个方案，而且该方案没有被评估过（论证中最后一句话是方案的内容介绍），所以我们由此可知，本题肯定是方案推理。

非牛，最近也在研究helr的论证方法，硬着头皮看得，因为没有时间换看别的方法了。这两题确实挺让我迷糊的 ...

嗯！你这么说好像就明白了！！！谢过~
