I chose to write about multiple sclerosis because I felt I could write a good EE on it since I’m interested in the diseases that affect the function of our brains. My research question changed from “how” to “what extent” in order to make my EE more evaluative rather than discursive. My initial concerns involved not finding any evidence about the correlation between geography and MS, however, after researching many sources online and in the library, my concerns shifted from the correlation of the two variables to finding reliable sources since some websites contradicted each other based on the biology of MS, which is a challenge I am currently facing. In order to deal with this, I will be using published studies that I can find online with the help of PubMed. Consequently, I will be using secondary data due to the ethical considerations involved with primary research.
