Yes, I have looked at the document at your first link, at https://onedrive.live.com/view.aspx?cid=E463C7E1E8737281&resid=E463C7E1E8737281!210&app=Word, which is working (the more recent link is not working at this time).
Assuming that I have been looking at the correct document (you do recognize my brief description of it?), what I found was a number of paragraph styles that were applied to text, and at least one of those styles has a line spacing of 1.5.
