Which set of lines from act I, scene V, of Shakespeare's Twelfth Night shows Olivia's interest in Cesario's (Viola's) social rank when Viola tries to woo Olivia on Orsino's behalf?

"What is your parentage? 'Above my fortunes, yet my state is well: I am a gentleman.' - I'll be sworn thou art." Olivia asks Cesario about his social position, she is seeing him as interesting and then finds out she is falling in love with him. In Elizabethan times, a person's social position was very important. Someone of a lower rank could not marry a person of a higher rank. Olivia is a beautiful lady of noble birth so she has to consider very carefully whom she marries to.
