GWD7-Q1

Although producer prices rose at an unexpectedly steep rate in September, analysts said that the increase resulted mostly from temporary factors and not necessarily foreshadowing that there would be a resurgence of inflation.

A.      factors and not necessarily foreshadowing that there would be

B.       factors and not necessarily that it foreshadowed

C.      factors and did not necessarily foreshadow

D.      factors, while not necessarily a foreshadowing of

E.       factors, while it did not necessarily foreshadow that there would be

答案选C 有没有那位NN能够提示下用while的那两个选项错在哪呢

个人认为错误主要是在foreshadow那边，直接用一个动词更加简洁。。。

个人认为, WHILE用在一般用在连接反观点上. 而原文用的AND, 是并列关系, 用WHILE则DISTORT了原文. 请指正.
