Final answer:
There is no accurate response provided because the excerpts are not related to the question about Desdemona and Othello in Cyprus; the text does not correspond with 'Othello' by William Shakespeare.
Step-by-step explanation:
The question asks how Othello convinces the men in Cyprus that his wife Desdemona should be allowed to accompany him. However, the provided excerpts do not relate to the play 'Othello' by William Shakespeare nor to the characters Othello and Desdemona. As such, it's not possible to give an accurate answer based on the given text. We would typically revisit the original text of 'Othello' to find the scene in which Othello speaks to the senators and Duke of Venice, arguing that Desdemona's presence is a comfort and support to him, essentially based on the themes of love and duty. Without the right context from the source material, any attempt at a detailed answer would be speculative and potentially incorrect.
