幾個 Longman 的題目 - 自學

想請問 Longman (Advanced Course) 裡的幾個問題!

P.224

139.If we _____ her foresight, our growth would have been more difficult.
(A) has
(B) did not have
(C) had
(D) had not had

正解:D，我選Ｂ，請指點一下＞＜


還有P.226的挑錯

153. Because tax rates were lower, net earnings, which are an indicator of
￣￣ ￣￣￣￣￣￣ ￣
A B C
a company's financial strength, was higher.
￣￣
D
正解：D
但我覺得很怪，which指的如果是前面的 tax rates，
那B選項不就應該是 indicators 嗎？


麻煩解惑了～感謝！ :)
