I have a problem with filling, can anyone help me and check the answers I have already written?

Explanation:

for number 5 i dont really think it was a disease i have been studying that topic for a project i haven't been able to determine from at least 12 different articles if its a disease or if its a chemical reaction due to the things put inside of e- cigarettes.
