This is a feedback that I got from my instructor
Some of the wording sounds like it came directly from the secondary sources. I did not go through and double check every sentence that sounded like another source, but to avoid plagiarism just make sure that you write your summary of the secondary sources in your own words.
In addition, what is your primary research contribution to this report? Remember that both primary research and secondary research are required in this research summary report.
Finally, make sure the information in each section belongs under that section heading. For example, there is information in the Background that maybe should be in the Causes section. It is worth one round of self-review to check that each section’s content is in the right section.
