Choice A, C, and D use hopefully to mean “it is hoped” rather than “ in a hopeful manner”; such usage still meets with strong and widespread opposition from editors, lexicographers, and authors of usage handbooks. In addition, because they misuse like, choices C and D are potentially ambiguous. As a comparative preposition, “like” relates noun to noun, not verb to verb; i.e., C and D seem to say that gravity waves do not interact with matter that is like electromagnetic waves. Choice e is incorrect because such as, like like, connects matter and waves, not interact and do. Choice B is the best answer for this difficult question.

is hoped 和 hopefully 有什么意思上的区别？

hopefully是口语化的表达，GMAT倾向于是用正规书面语，所以it is hoped优于hopefully。

C  中的hopefully 得放在will后, will hopefully enable .
