“Improving the Intro, Problem Statement, and Purpose Statement in a Draft Proposal”

The draft proposal is written and it has some comments for edits from the professor, below is some examples of the edits mentioned. 
– The intro should introduce the topic with a focus on the aspect that you will address, the current research, and the gap in knowledge on the topic (which is what your research will address). The known research and gap are critical in a proposal intro (as opposed to the intro of a research paper).
– The Problem Statement should be one sentence. If I asked you in to tell me the problem in one sentence, what would it be?
– The Purpose Statement should be one sentence. It gives the purpose of this research – how it fills the gap in research relating to the problem that your research will cover.
