 There are 4 beats per measure in that piece. The quarter note gets the beat. I'm not entirely sure about the third one. If I were to guess, I'd say measure 8 because that measure contains the forte symbol first. And the piece begins on a downbeat.
Hop this helps! I'm taking music theory in high school this year so I have some knowledge. ;)
