请问新东方逻辑section16-15题

15. In the course of her researches, a historian recently

   found two documents mentioning the same person,

   Erich Schnitzler. One, dated May 3, 1739, is a

   record of Schnitzler’s arrest for peddling without a

   license. The second, undated, is a statement by

   Schnitzler asserting that he has been peddling off

   and on for 20 years.

   The facts above best support which of the following

   conclusions?

   (A) Schnitzler started peddling around 1719.

   (B) Schnitzler was arrested repeatedly for peddling.

   (C) The undated document was written before 1765.

   (D) The arrest record was written after the undated

       document.

   (E) The arrest record provides better evidence that

       Schnitzler peddled than does the undated

       document.

答案是C，1765这个时间是怎么推算到的？我觉得D好。大家能为我看看吗？谢谢大家了！

这是归纳题，从题目的条件中不能完全得出D

这道题目当时在新东方上课时老师说只可以退出1719到1759，所以C是绝对正确的

这道题目并不是典型的ets出题思路，所以你不用太担心的

有关出题思路只是个人的感觉而已，可笑的是我自己也说不清楚，大概按照归纳、削弱、加强、解决问题纷纷类吧。这需要你自己不断的思考总结。我当时把og和补充材料看了好多遍，又作了一大半lsat，才有了自己遇到新题目是的熟悉感。你可以看看网上大牛们的逻辑体会和总结，我当时看了mindfree和小安的文章后受益匪浅。

通过持续的实践找到你自己分析问题的思路和解决问题的方法，这才是crack gmat的法宝

good luck!
