Some Behavioral Scientists Argue That Giving Applied Research Priority Over

Some behavioral scientists argue that giving applied research priority over basic research is shortsighted because

A) the history of science has shown that important practical advances generally come from an understanding of basic processes.
B) basic research can suggest ways of developing interventions for applied problems.
C) the distinction between basic and applied research is somewhat artificial: Action research can generate basic knowledge while trying to solve important practical problems.
D) of all of the above reasons.
