是选D。duplicate可以指重复。而且research duplicate完全合理啊。A也是削弱,但不如D强烈。

A is irrelevant. Government gives universities grant money, which is free. Even if the university sells the patent, the government would still give grant money to the university.

LZ you understanding of the word "duplicate" is right and you understanding of patent is right as well. If D is true, university would not acquire many patents. Thus, its plan to sell patent right in order to support its undergraduate teaching activities would not work. D is the correct answer.
