討論一下 (A) each of which are ... 主動詞不一致; 另外主軸句意似乎意猶未盡
i.e. When an active tooth in the shark’s jaws is lost or worn down, many spare teeth lie in seemingly limitless reserve. 句意不太合理呀! (當鯊魚的現役牙齒掉了或磨損了,許多的備用齒仰賴看似無限的儲存)
確定答案是 (A) 嗎?

(B) which = jaws , 句意不合理
(C) 主動詞不一致; one 多餘
(D) 沒有主要子句

好像只能選 (E)

這一題的答案我也覺得是(E)吔,因為each of which的動詞怎麼會用are呢???

因為文法上來看只有(E)沒有錯誤
