I got through this one by just realizing that it was either of the two conclusions stated in the argument. When I saw premise, evidence (another form of premise) and background choices, as what this part served in the argument, I immediately eliminated those. I did notice that J.Y. explained the other choices in more detail.

I didn't eliminate answer choice A, and chose answer choice B because I didn't understand what answer choice A meant.

I have viewed the videos on a Note 2 and Note 4 now. I've been using Google Chrome and have had no issues. The only thing different from the desktop experience is that I can't fast forward videos. Also, are you rooted or stock?

Thanks! I really am starting to see the distinction between the two!

I picked A. Can you explain, in depth, why this wasn't the correct answer? Even after blind review, I strongly thought it was A.
