Final answer:
Desdemona's repeated questioning of Othello about talking to Cassio makes her appear guilty of cuckoldry in Shakespeare's play 'Othello'.
Step-by-step explanation:
Desdemona repeatedly asks Othello when he will talk with Cassio, which leads her to appear guilty of cuckoldry. In the play 'Othello' by William Shakespeare, Desdemona's persistent questioning causes Othello to suspect her of infidelity, as he believes she is trying to hide something or have secret meetings with Cassio. This eventually contributes to Othello's misguided beliefs and the tragic events that unfold.
