Final answer:
The claim that Blanche routinely calls Stanley a 'Guido' is false, as this term is not used in Tennessee Williams' 'A Streetcar Named Desire'.
Step-by-step explanation:
The statement that Blanche routinely calls Stanley a Guido, a derogatory term for his heritage, is false. In the play A Streetcar Named Desire by Tennessee Williams, Blanche does not use the term 'Guido' to refer to Stanley. The term 'Guido' itself is a derogatory term often directed toward Italian Americans, but it is not used by Blanche in the text.
Stanley is of Polish origin, and while there is tension and insult-trading between Blanche and Stanley, the specific use of the term 'Guido' is not part of their interactions in the play.
