1- The intent of this text is telling us about the biography of a man's self portrait ed life, while getting the point across the author most likely was trying to inform us on how "men can do anything with themselves if they will" During the renaissance period. I know this because, the story at the beginning was left with dialogue it quotes that " “His genius was so versatile that you might almost judge all the fine arts to be his..." If people are talking good about someone high chance they have done something successful in life, This quote connects to another source stated by, "men can do anything with themselves if they will". The author was referring men to people who are reading this and also the successful man that achieved things!
2- A part that relates to the "renaissance" are, "He learned music without teachers and his compositions were approved by learned musicians"
3- (you can put any questions you have if not remove this and put "N/A"!!
I believe the answer to your question will be the first option given.
