Final answer:
The statement about Blanche seeing marriage as her only survival route is true. The historical and literary contexts show that women often depended on marriage for social and financial stability.
Step-by-step explanation:
The statement that Blanche sees marriage as her only way of survival out of her situation is true. Historical context is vital for understanding this perspective, especially considering societal norms concerning gender roles during the Middle Ages and even in later historical settings, including the 19th and early 20th centuries. Women in many situations had limited options for independence and securing their futures, often relying on marriage for social standing and financial security.
For example, the historical figure Blanche of Castile, after her husband's death, showed remarkable prowess in securing her son's kingdom during a tumultuous period. However, this isn’t necessarily indicative of all women's experiences, as their capacity to manage in the absence of men varied widely. Nonetheless, in many literary contexts, such as in Tennessee Williams' "A Streetcar Named Desire," Blanche DuBois views marriage, or the securing of a male protector, as a form of survival, a reflection of gender dynamics of the time.
