Paragraph 1 : The problem in context

Donts : the topic is too broad such that the reader already know it, or, it is to narrow that makes the reader gets lost on the technicalities.

Paragraph 2 : The gap in knowledge

Dos: Excite the reader’s curiosity by presenting what is known and unknown about the chosen topic. Your literature survey or review should highlight the information gap along with uncertainties involved. You should specify your citation (s) for each point raised. Having read this paragraph, the reader’s will beg for a study that could fill in the gap. Then, you give a preview of your paper.

Donts : Summarize all literatures related to the topic but fail both in identifying the gap and addressing the study direction. Give too many citations for one point.
