Othello questions

The circumstantial evidence that is added to Othello's case against Desdemona is the handkerchief that Othello gave to her, but was found to be with Cassio

I find it very unplausable that he Othello looked on right when Cassio wS tossed the handkerchief, I believe it was put in for dramatic effect. The handkerchief is very important in the play because it symbolized Othello's love for Desdemona, and now it serves as evidence for Othello to suspect Desdemona of infidelity. The hints are found in the reaction Othello gets from seeing the handkerchief with Cassio.

The perceived evidence of the handkerchief and Cassio's supposed confession of the two prevent Othello from being moved by Desdemona's appeal

The conversation between Emilia and Desdemona reveal that Emilia does not like how women get treated and feels that women are like men in almost all characteristic whereas it reveals about Desdemona that she is honorable and is willing to stay and stand on what she believes is truth even though she knows she is going to die.

The scene with Casio, Othello, and Iago contains dramatic irony because the audience knows the reasoning fir Iagos questioning but Cassio does not.

Act 5 questions

The events that lead to Iago's unmasking start with Emilia's confessions about how Iago axles her for the handkerchief and how Iago lied and conjured up the whole schemes with his lies.

Iago stabs and kills Roderigo so that his plan is not ruined. He knows that if Cassio and the others find Roderigo to be a friend of Iago they would put the information together and discover Iago for what he is.

I believe that A mixture of Jealousy and a wish to be a public avenger are why compells Othello to kill Desdemona.
