Octaves in 2nd to last measure of line 2 on last page are 2 distinct octaves. Is it the same for 2nd to last measure, 2nd to last line on 2nd page?

Dynamics then consistency of theme THEN memorization.

If a measure has the first chord marked sfz, are the subsequent notes f until marked otherwise?
