Step-by-step explanation:
No, Mozart did not revise Symphony No. 40 to include solo vocalists and a choir as performers in the fourth movement. Symphony No. 40 is a purely instrumental work composed by Mozart in 1788. It consists of four movements: Allegro molto, Andante, Menuetto Allegretto, and Finale Allegro assai. None of these movements involve solo vocalists or a choir.
