How does shakespeare’s use of literary techniques in much ado about nothing serve to reveal larger human truths?

In the play “Much Ado About Nothing” Shakespeare used both verse and prose in it. As prose represents a language of logical thought, while verse is the language of emotion and self-reflection. It was during Shakespeare’s time that when a dramatic character speaks in poetry it speaks from his heart rather than in prose. Beatrice and Benedick spoke in prose to provide logic and substantiality in their arguments against each other. Benedick used witty prose to defend himself and Beatrice used prose to decrease her emotional appeal in her arguments.

Shakespeare in his play “Much Ado About Nothing” has used the theme of mishearing and passing the wrong information. The chaos created by this results in the misunderstandings throughout the play.The play “Much Ado About Nothing” by Shakespeare engages itself in several confusions and misconceptions about the characters about each other. Antonio believes that Don Pedro will propose to Hero at the dance. Antonio’s servant had over-heard Don Pedro talking to Claudio that he will confess his proposal of love to Hero that very night. After over-hearing the news, Antonio's servant delivers it to Antonio. Later, Antonio tells Leonato about the news after which Leonato decides to warn Hero about it.

The process of overhearing, misunderstanding, and plotting goes on until the end when everything gets resolved on a happy note.

that is true because that is something they fulfill for their work.
