A. had elected early retirement rather than face
B.had elected early retirement instead of facing
C.have elected retiring early instead of facing
D.have elected to retire early rather than facing
E.have elected to retire early rather than face
這題選E, OV的解釋說 face and to retire 平行, 但是省略 to.
但我不懂為什麼可以省略to 也看不出來~

其他答案看起來都不太對 所以最後選E
請問這種題目 是比較其他答案 顯得較好 才選嘛?
