大全sec12-13，详解？

13.   Some analysts point out that because people are becoming accustomed to a steady inflation rate of four to five percent, businesses found that they could raise prices according to this amount without thereby provoking strong public reaction.

(A) found that they could raise prices according to this amount without thereby provoking

(B) found that they were capable of raising prices by this amount and not provoke

(C) find that they are capable of raising prices by this amount and not provoke

(D) are finding that they can raise prices by this amount without provoking（D）

(E) are finding that they can raise prices according to this amount and will not thereby provoke

大全注释不太详细

请NN们给个详细点的解释！谢谢

我查了by 有“按...计算”的意思，是要去这个意思才用by吗，用according to 表示“按照，根据”的意思不可以吗，还是问题出在raise prices 上，是固定搭配吗。

还有就是without thereby的问题，能具体讲讲错在哪了吗？谢谢

according to 不合逻辑是什么意思啊

斑竹太强了，为什么我就理解不到这层意思呢？敢问是从哪里分析来的啊？？
