Answer:
Scholars began to question the Church authority.
Explanation:
The Catholic Church in the 14th and 15th centuries faced many problems because of the failure of the Papal authority to provide spiritual leadership. The religious sensibility of the people had heightened with wars, diseases, epidemics, and crop failures. The Church also faced criticism of its institutional degeneration and corruption.
Individual attempts for reforms were made by John Wycliffe in England and Jon Hus in Bohemia. But they were crushed and declared heretics.
