So, we need to figure out what makes a "resource provider institution" different than the other three classes of faculty rights.
The second paragraph describes three of them: Supramaximalist, Maximalist, and Resource Provider.
The third paragraph describes why these classifications are not quite perfect.
The fourth paragraph introduces the fourth class of faculty rights and advocates for it.
To answer this question we should look at the bottom of the second paragraph where "resource provider institutions" are discussed. There, the last line says, "Of course, what constitutes significant use of resources is a matter of institutional judgment."
Answer choices (A) and (E) are the best after a first quick run through.
(A) is wrong in that the question is not how to decide what are institution resources and what are nonuniversity resources, but rather how much university were used.
(B) discusses financial benefit, rather than split of resources.
(C) is not true, faculty under this system are still being exploited.
(D) is not true. A resource provider institution would not require that work is done completely apart from the institution.
(E) correctly describes the proportion of university and nonuniversity resources and how the split is open to institutional judgment.
Hopefully that helps! Let me know if you're still having a hard time seeing it...
