Answer: So she could find employment
Step-by-step explanation:
In the play, ''Twelfth Night '' by William Shakespeare, Viola was shipwrecked and rescued but was now in a foreign land. She therefore needed a way to support herself and so needed employment.
In order to get over gender barriers to employment, she disguised herself as a man and picked the name Cessario to enter into the service of Duke Orsino, who rules Illyria.
