There was a question about how to play the chord e,g,bflat and sharp and c in the second section with the repeated A in the left hand. If I'm not mistaken, the sharp refers to the c. This would make the chord a diminished seventh csharp,e,g,bflat in first inversion which resolves to the next chord which is the tonic chord of d minor in second inversion, taking the left hand A as the lowest note. Hope this technical explanation helps!
