A native of Kansas who had a bank account at age seven and was paying the family bills at age eleven, Olve Ann Beech's business mind was behind Beech Aviation from the 1930's when she and her husband fiunded the company, until its sale in 1980.
(A) Olve Ann Beech's business mind was
(B) it was the business mind of Olive Ann Beech that was
(C) Olive Ann Beech was the one whose business mind was
(D) Olive Ann Beech was the business mind
(E) the business mind of Olive Ann Beech was
正確選項: D
做此題時我選 C, 我是從第一句A native of Kansas 直接從ACD 這3個選項去選~ ,
因為這3個人是以人為開頭呼應前一句 A native of Kansas ,
我沒選D 是因為 D 選項的意思讓我解釋成 Olive Ann Beech = ( was ) the business mind ,
所以剩A 與 C, 那最後我選C 了......

不知道這樣的觀念是不是一剛開始就錯了, 不過我仍無法理解為何D 是正確答案......
請各位版有幫忙解惑~
謝謝~~~
