what is the structure of puting a question within a sentence in a dissertation

Another useful clue is found in the Latin origin of the word – dissertation comes from a Latin word ‘dissertare’ = ‘to debate’.
Here’s another definition that underlines some more important characteristics of a dissertation: “a substantial paper that is typically based on original research and that gives evidence of the candidate’s mastery both of her own subject and of scholarly method.”
