Read the excerpt from Act IV of Julius Caesar. Brutus: (Suddenly melting, he says gently,) Sheathe your dagger. (He pushes the weapon back to Cassius.) Be angry when you will. Do what you will. (He puts his hand to his head.) O Cassius, I am sick of many griefs. (He gives a great sigh.) Portia is dead. Cassius: (Shocked) Portia? (With wonder) How escaped I killing when I crossed you so? Brutus: (Bravely) Speak no more of her. (His servant Lucius brings in a tray with wine, two bowls, a book, and a lighted candle.) Give me a bowl of wine. (He and Cassius raise bowls and toast each other.) In this I bury all unkindness, Cassius. How does Portia's death in Julius Caesar affect Brutus?

It makes him unwilling to fight with Cassius.
It emphasizes for him how much he loved her.
It causes him to be unconcerned if he lives or dies.
It brings him courage to face the future.
