In which two ways does the fourth paragraph contribute to the development of ideas in the passage? Many vegetarian supporters would say the best thing you can do for the environment is to stop eating meat. Some estimates show that the amount of water used just for farming equals the amount of water used for everything else in the United States combined.

Emilia gives Iago Desdemona's handkerchief, which he later plants in Cassio's room in order to make Desdemona seem unfaithful.

Explanation:

Iago, passed over for a promotion by Othello, deeply hates Othello and pretends to be his friend with an ultimate goal to destroy him.

Iago's wife, Emilia, plays a crucial role in this plot. At first, it seems that Emilia is rather passive character. She is naive and just listens to her husband whatever the cost. When she finds Desdemona's handkerchief, she states that, on multiple occasions, her husband asked her to steal it for him. She is happy to finally bring it to him. Iago plants a handkerchief in Cassio's room, as a proof for Othello that his wife has been unfaithful.

As the story progresses, Emilia becomes suspicious, and when Othello kills Desdemona for her infidelity, Emilia reveals to him that the handkerchief was stolen. In this way, Emilia exposes Iago and his true intentions, and Iago kills her.
