Fixing the endpoints first:
Before any research can influence practice, the intended users must first become aware that the research exists, so awareness (D) must be the starting point, this alone eliminates any sequence not beginning with (D). At the other end, the ultimate goal of the whole process is for proven findings to be adopted into everyday practice, so "research into practice" (B) must be the final stage, not an intermediate one. Between these two ends, a piece of research must first be judged worthwhile through evaluation (A) before anyone invests resources in testing it on the ground through a trial (C); evaluating comes before trialling, not after. This fixes the middle order as evaluation then trial, giving the complete sequence Awareness, Evaluation, Trial, Practice, i.e., (D), (A), (C), (B), which is option (1).
