12. After gradual declension down to about 39 hours in 1970, the workweek in the United States has steadily increased to the point that the average worker now puts in an estimated 164 extra hours of paid labor a year.
(A) After gradual declension down
(B) Following a gradual declension down
(C) After gradual declining down
(D) After gradually declining
(E) Following gradually declining
答案是:D
問題一:OG裡面提到Replacing declension with decline would be acceptable(到這哩,沒有問題),but it is preferable to use the participle:declining (這句話,有問題,為什麼OG要這麼寫呢?)
問題二:答案E選項提到Phrase must be introduce by a preposition(after), not a participle(following)-->這句話,看不懂他的意涵是什麼耶??
請問在做這題的時候,要怎麼從答案D跟E做決選呢?
