What is the purpose of Emilia's use of rhetorical questions in the following lines?
What is it that they do
When they change us for others? Is it sport?
I think it is. And doth affection breed it?
I think it does. Is't frailty that thus errs?
It is so too. And have not we affections
Desires for sport, and frailty, as men have?
Then let them use us well; else let them know
The ills we do, their ills instruct us so (4.3.99-106)
