I want to know the answer to the following question:
Which disease did Arline succumb to?
All the background I'm provided with is that "While pursuing his PhD at Princeton, Feynman married his high school sweetheart, Arline Greenbaum (often misspelled "Arlene"), despite the knowledge that she was seriously ill with tuberculosis—an incurable disease at the time.". Is that enough to answer the question?
Answer: yes
