Good Luck D Ravindran best wishes.

D. Ravindran reviewing a body of knowledge is generally guided by an objective of highlighting which sources are key in the research area and what could potentially be missing. As such the gap that is identified from such a theoretical review guides the formulation of research question, objectives and the development of testable hypotheses. Citing some of the theoretical sources highlights what is important and therefore what adds weight onto the line of argument and the potential areas that could be contributed to. Interesting.
