Final answer:
Sandra Cisneros, the author of 'The House on Mango Street', has never held the job of a lawyer; she has been a teacher and is notably a writer. Option 4.
Step-by-step explanation:
The author of The House on Mango Street, Sandra Cisneros, has held various jobs throughout her career, but being a lawyer is not one of them. She has indeed worked as a teacher, and her vocation as a writer is evident from her publication of the novel.
While her struggles with cultural identity might have influenced her imaginative expression, possibly aligning her with the traits of an artist, there is no direct reference to her having a career specifically as an artist. Therefore, amongst the options provided, Sandra Cisneros has not worked professionally as a lawyer.
So option 4.
