How does portia's legal argument unfold?

In Shakespeare's "The Merchant of Venice," Portia's legal argument unfolds through her clever use of rhetoric and legal precedent in the courtroom. Disguised as a young lawyer, she first acknowledges Shylock's right to his bond but then emphasizes mercy over justice, arguing that mercy is a divine quality. She cleverly points out that while Shylock is entitled to a pound of flesh, the contract does not permit him to spill any blood, thus exposing the flaw in his claim. Her argument ultimately turns the case in favor of Antonio, showcasing her intelligence and legal acumen.
