Engelsk opgave - hjælp

Ved faktisk godt hvad thesis statement er, men jeg ved bare ikke om den der sætning er en. Jeg gætter på at 1. = Yes, men har ingen grund. Kan i hjælpe?

har lavet det selv: "Yes, it is a thesis statement, because it is clear that it leaves no doubt in your mind or the reader’s mind about what stand you are going to take about the issue, or what the issue is. The statement also is trying to convince readers of something, change their minds about something, or support them to do something. "
