It is possible that future spacecraft will be slowly propelled through almost empty space within the solar system, not by jets of gas, but by the force of photons of sunlight pushing on thin plastic sails.
(A)It is possible that future spacecraft will be slowly propelled
(B)It is possible for future spacecraft to be propelled slowly
(C)Future spacecraft could be propelled slowly possibly
(D)Future spacecraft could possibly slowly be propelled
(E)It could be possible that future spacecraft be propelled slowly

我主要想請教一下
這題雖是(A)
那(B)主要的錯誤
以及何種狀況可用(B)比較好啊

[Pufa]

A強調的是that之後的事實，
B強調的是未來的spacecraft。
兩個意思不一樣。
參考參考

不知道大家怎麼想^^

[hsinchen]

(B)有雙向修飾的問題
slowly修飾前面的動詞propelled,又修飾後面的副詞片語through almost empty space(介+N.)
大家參考看看吧

(c)(d)(e)不選有could possible造成語意重複
