For this one my BGO told me that it doesn't have to be some very tragic event. Again, tragedy/adversity is not something we can control. Happens to some people and not to others, and so you can't force yourself to have an adversity. More so, if you are lacking something in your application use the question as a way to explain it. For me, I have no sports and and a large lack of physical engagement. I have reasons for that though, which aren't the most grievous or serious, but reasons none the less. I used that part of the application to explain why my physical engagement and sports was lacking and more so, what I learned and how I was planning on fixing it. Like said before, if you really have NOTHING don't put in something trivial like "my internet cut out two times while opening the application" but really use it as a way to discuss why some parts of the application are missing (if any). Also great if you have lower academic scores, so you can explain why.
