The decision to change careers is difficult and____.
A)requires confidence in one's abilities
B)condifence required in one's abilities
C)to require confidence in oe's abilities
D)one's abilities requiring cofidence

答案是A
我的問題是 and是對等連辭 旦我想到的是找的形容詞和difficult來對等 一樣是形容詞
旦書上寫的 確定以 is difficult 單一個單位 來找動詞來對等 ??
為什麼呢??
是我本身的想法有錯誤嗎 都該是以動詞開始為個單位來對等嗎??

對等連接詞沒有一定從哪裡開始連接
如果前面是(單字) 後面就連(單字)
如果前面是(句子)後面就是(句子)
如果前面是(介係詞片語) 後面就是(介係詞片語).......

(is diffcult) and (requires confidence)+(in one's abilities)
( V+ ADJ ) ( V +ADJ ) (介片:附屬結構 , 不管他)
