Since digital recording offers essentially perfect reproduction—on compact discs, digital audiotapes, or digital videodiscs—audiophiles can accumulate vast collections of music, transferring them from one format to another, copying it, and digitally altering it with little effort and not damaging the sound quality.
A. music, transferring them from one format to another, copying it, and digitally altering it with little effort and not damaging
B. music, transferring it from one format to another, copying it, and digitally altering it with little effort and no damage to
C. music, transferring them from one format to another, copy them, and digitally alter them with little effort and no damage to
D. music and transfer it from one format to another, copy it, and then digitally altering it with little effort and not damaging
E. music and transfer it from one format to another, copying it, and digitally alter it with little effort and no damage to
Parallelism; Agreement

虽然这题我做对了，而且从几个选项来看，也只有平行的最一致，但是有些糊涂了，为什么代词用的是IT，而非them， collections of music ,不是应该用复数的吗？正如下面这题， force of Jupiter and its moons 需要用causes的单数形式？

On the surface of Jupiter's moon Europa, water remains frozen, but the gravitational force of Jupiter and its other moons cause contractions that may generate so much heat that it would melt ice below Europa’s surface.
A. moons cause contractions that may generate so much heat that it would melt
B. moons cause contractions, with enough heat generated for melting
C. moons causes contractions that may generate enough heat to melt
D. moons, causing contractions, may generate so much heat to melt
E. moons, which causes contractions, may generate enough heat for melting


难道collections of music是应该看作一个整体来理解的吗？ 见到带OF神马的，判断单复数，顿时就凌乱了~~~ 呃~~~还求NN详解！！！！ 谢谢啦~~~

根据句意这里只指代music，所以这里用it. 而不用them.

说实话我怎么觉得collections 也是可以被transfer  copy  alter的呢。。所以再想是不是上面我说的“them是个整体，不能transfer from one format to another”

这还应该从句意来理解，
第一题，还应该从平行的角度来看，transferring it from one format to another, copying it, and digitally altering it ，三个it平行，都指向了music。而不指代collections。

第二题，请认真读题，causes的发出者为the gravitational force 是一种东西，所以单数。
