Social order is imposed with marriage at the end of the play,a more equal relationship between the men and women is possible. Do you agree?
Yes, a more equal relationship between the men and women is possible, largely because Hero and Claudio are together, and because their marriage heals a very harsh crack in male/female relationships. Her reputation is restored, and, at least as important for equality, he realizes how much he loves her.
Social order…no, I wouldn't really agree that it is "imposed." That seems to harsh a term for the coaxing that is done with Beatrice and Benedict. It is…more smoothly established, now that those two loose cannons are yoked.
It is not, however, imposed or complete; John is still free.
