First, you brought up commas. I was only talking about the apostrophe becuase you forgot it, and it caused your sentence's definition to be altered, then you replied with commas. There was no need for ellipses. From what you just said, you've forgotten what a thesis is, or you never had a thorough understanding of its concept. Bye the way, I'm a full-time student who works part-time, so I don't see why you're struggling because just like you, I'm currently on my phone.
