Why Is Inherency Crucial to Constructing a Prima Facie Case

Why is inherency crucial to constructing a prima facie case?

A) Advocates must identify the cause(s) of a problem or a need for knowledge.
B) Advocates must determine whether inherency is "structural" or "attitudinal" because attitudinal inherency can be more difficult to overcome.
C) We take it as a given that if the cause of a problem cannot be found, we cannot determine how to solve it; if there is nothing to stimulate a quest for knowledge, we are unlikely to search for it.
D) We generally recognize that because the advocate seeks change, she has a more difficult task because she is required to use cause-effect reasoning.
