The intellectual explosion we call humanism was largely an intellectual, rather than academic, exchange between diverse individuals all over Europe.
Answer: Option C.
Step-by-step explanation:
Humanism depended more on the personal contact between the human beings. It was not a systematic instruction that took place at schools and universities.
Because of the personal contact between the people as a result of the humanism and because of the private study, many significant works were inspired of that time by this. Reading humanist works often seems like overhearing a conversation between friends.
