I want to know the answer to the following question:
What did the pope die of?
All the background I'm provided with is that "On 5 July 2013, Pope Francis – bypassing the traditionally required second miracle – declared John XXIII a saint, after unanimous agreement by a consistory, or meeting, of the College of Cardinals, based on the fact that he was considered to have lived a virtuous, model lifestyle, and because of the good for the Church which had come from his having opened the Second Vatican Council.". Is that enough to answer the question?
Answer: no
