PREP 模考时的一题

The commission’s office of compliance, inspection, and investigations plans to intensify its security of stock analysts to investigate not only whether research is an independent function at brokerage firms, but also whether conflicts results when analysts own the stocks they write about or when they are paid for their work by a firm’s investment banking division.
A. to investigate not only whether research is an independent function at brokerage firms, but also whether conflicts results when analysts own the stocks they write about or when they are paid

B. to investigate not only whether research is an independent function at brokerage firms, but also if conflicts results when analysts own the stocks they write about or they are

C. to not only investigate whether or not research is an independent function at brokerage firms, but also if conflicts results when analysts own the stocks they write about or are

D. not only to investigate whether or not research is an independent function at brokerage firms, but also whether conflicts result when analysts own the stocks they write about or are

E. not only to investigate whether research is an independent function at brokerage firms, but also whether conflicts result when analysts own the stocks they write about or when



答案是A，但我有两个问题：

1weather 和if 在本句中有什么具体区别

2but also whether conflicts results 中  conflicts results 两个词为什么都有S，各是什么词性？

花子落落

表示是否时，只能用whether，if容易造成歧义。


关于那个两个加了s的词大家ms也是有争议的~但是总体来说A比较象答案~
