Setting up a corporation requires more paperwork and legal provison【 than to establish either a proprietorship or a partnership.】
A than to establish either a proprietorship or a partnership
B than what it requires to establish either a proprietorship or a partnership
C than to either establish a proprietorship or a partnership
D than establishing either a proprietorship or a partnership
E than establishing proprietorships and partnerships

OA是D 我记得有一个例子是 Jim ate more than Tom [did].这里的did不是不可以省略吗
答案D是不是违背了这个原则呢？还是我记错了？

只要没有歧义就可以省，这里不存在把paperwork and legal provison与establishing either a proprietorship or a partnership比的歧义，所以可以省

我的理解：
首先than后与setting比较，所以肯定是-ing
其次按形式对称就可得到D
省略的原则就是前面有的避免重复故省

介词和助动词是尽量补出的，不是一定。也就是说不补出不一定错，如果补错了却一定是错的。如果没有更明显的错误，才会考虑助动词补出原则。
