Question

Okay, so I'm getting the hang of this. Anyway, the first "Theme" of Mozart's 21st Piano Concerto is plain to me. But where does the second begin? And what is it? Again, I have to write a paper on this, and besides a VERY basic, rudimentary comprehension, I have no technical understanding of music. :(

I cant point to the bar. I don't have the music, but it is described here.
