[求助]白勇语法上的一道题

In terms of physics, the characteristic feature of the roller coaster is that the cars' potential entergy, gained through their being lifted by a chain drive through the Earth's grabity to the top of the first drop, has been conberted to kinetic energy by the time the ride ends.

(A)cars' potential energy, gained through their being lifted by a chain drive

(B)cars' potential energy, a gain achieved as they are lifted by a chain drive

(C)potential energy from the cars' being lifted by a chain dribve

(D)potential energy of the cars, gained as a chain dribe lifts them

(E)potential energy gained by the cars, being achieved while a chain drive lifts them

答案说是D，gained跳过介词短语of the cars 修饰potential energy

解释说，AC中介词错误的接了one's being done的搭配，

E则是being achiebed while... 作定语修饰the cars,逻辑意思不合理

B是a gain 作为动作性名词，做物质名词potential energy 的同位语缺乏解释力

我不明白为什么只能选D，D读起来也挺别扭的，请各位大虾不吝解答

a b错 因为car加所有格

c错car's being done

d e中选一个

e为什么一定错 请nn解释
