I want to know the answer to the following question:
When did da Vinci die?
All the background I'm provided with is that "Their contemporary, Leonardo da Vinci (1452–1519) said, "If you find from your own experience that something is a fact and it contradicts what some authority has written down, then you must abandon the authority and base your reasoning on your own findings."". Is that enough to answer the question?
Answer: yes
