in this excerpt, what effect does the adjective "mighty” have that the adjective "great” would not?

“mighty” shows that sheridan’s speeches are longer than most “great” speeches.
“mighty” reflects how powerful and influential the speeches were to douglass in a way that “great” would not.
“mighty” and “great” mean essentially the same thing, so there is not much difference in their effect.
“mighty” reflects a harsh bitterness that would not be reflected with the word “great.”

"Mighty” reflects how powerful and influential the speeches were to Douglass in a way that “great” would not.

Mighty means possessing power or authority. These elements are not exactly part of the definition of the word great, which simply means large, remarkable, or predominant. With mighty, there is a connotation of significance and impact. Indeed, the narrator tells us that these speeches fascinated him ("unabated interest") and influenced his thinking ("they gave tongue to interesting thoughts of my own soul").

B. Mighty reflects how powerful and infuencial the speeches were to Douglass in a way that "Great" would  not.
