Not great – Find–the–Line Review

I'm glad everyone else finds this so easy. I can't figure it out. On the second picture in the tutorial, I don't know where to tap, or what it does. It shows a hand scrolling across the screen so I follow it; then what? I go across again and again, and I get nowhere. I need directions – WORDS.
