[求助]大全16-15

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.（C）

(E) The arrest record provides better evidence that Schnitzler peddled than does the undated document.

选b了不认识peddle所以还以为是进所里什么的意思，在加上后来的on and off 就选了b~~~ 

c没明白，1765是从哪来的？1766就不行了？还有就是这道题根据题目给的两个条件无法断定Erich Schnitzler开始peddling的起始时间点（有点像math里的ds），而且第二个条件是说到那个undated的时间Erich Schnitzler peddle了20年，无法推出其总共peddle了多年，所以两个documents并无关联~

不好意思，没说明白~答案是c

简单得很：

1739+20=1759, so the undated doc must have been written before 1765.

啊~突然觉悟了~才发现自己提了个多么白痴的问题~多谢指教
