Final answer:
The question does not provide enough context to determine which woman or what master's degree is being referred to for receiving in 1965. It is impossible to provide an accurate answer without more information.
Step-by-step explanation:
The question seems to pertain to a specific unidentified woman who achieved her Master's degree in 1965. Given the lack of context, it is uncertain which woman the question refers to, which makes providing an accurate and direct response on what master's degree she received impossible without additional information.
Historical women in academia around or before 1965 who had significant educational achievements include individuals like Cecilia Payne-Gaposchkin, who completed her doctoral thesis in 1925, and Margaret Floy Washburn, the first woman to earn a doctorate degree in psychology in 1894. Each contributed substantially to their respective fields, with Payne-Gaposchkin's work underpinning the understanding of stellar compositions and Washburn's shaping comparative psychology for over two decades. Due to insufficient details in the question, however, one can only speculate about the identity of the woman in question.
