Step-by-step explanation:
Fundamentalism is a religious ideology characterized by a belief that holy books should be taken literally. It is the belief that religious texts are the authoritative source for answering important political and social questions.

This form of religious extremism is based on the reliance on the will of God as revealed in a book of revelation.
