Feedback on Report Introduction

I received an email from my supervisor on how I can improve my introduction. She advised me to start with a rationale for my work and to include why I have chosen to focus on Parkinson's and use secondary research rather than primary. She also said that I should write why I felt research into research programmes about Parkinson's is important. There's a lot I can add to my introduction so I might give myself a day to work on this. I think one of my successes on this project is being able to use the time I spend discussing with my supervisor effectively by taking notes and keeping a record on what I'll need to do.
