LSAT-10-2-19 will occasinally blabla..取非后应该怎么理解？

superdennis

A university should not be entitled to patent the inventions of its faculty members. Universities, as guarantors of intellectual freedom, should encourage the free flow of ideas and the general dissemination of knowledge. Yet a university that retains the right to patent the inventions of its faculty members has a motive to suppress information about a potentially valuable discovery until the patent for it has been secured. Clearly, suppressing information concerning such discoveries is incompatible with the university’s obligation to promote the free flow of ideas.

19. Which one of the following is an assumption that the argument makes?

(A) Universities are the only institutions that have an obligation to guarantee intellectual freedom.

(B) Most inventions by university faculty members would be profitable if patented.

(C) Publication of reports on research is the only practical way to disseminate information concerning new discoveries.

(D) Universities that have a motive to suppress information concerning discoveries by their faculty members will occasionally act on that motive.

(E) If the inventions of a university faculty member are not patented by that university, then they will be patented by the faculty member instead

答案是D，ABCE都错我明白，可是D的这个will occasionally blablala...应该怎么取非？怎么理解？

是大学不“偶尔”act on that motive(即经常act on..)

还是取非成连偶尔都没有，即从不act on...

谢谢大家，帮忙

"是大学不“偶尔”act on that motive(即经常act on..) 还是取非成连偶尔都没有，即从不act on..."

从不act on. Occasionaly in LSAT means > 0, which can be 100%. So negative of occasion is 0. But I am not a very big supporter of 取非, becuase if you understand the logic, you see the assumption right away.  取非 requires you to understand the logic first.

The logic:

There is a gap between premise and conclusion. Basically it's saying

If entitled to patent, university has movtive to supress free flow of idea, and it's incompatible with university's goal, so they should not be entitled to patent. 

See the gap?

It's the same as saying 

If you are given a TV,  you have motive to watch it a lot and it's bad to your grade,  so you should not be given a TV .
