can someone help me out
the views expressed in the passage illustrate which of the following important changes within the Christian religion between 1520 and 1750?

The spread of Christianity throughout Western Europe
The political authority held by Catholics throughout all of Europe
The subdivision of Christianity into different sects within Western Europe
The unity of Christian doctrine among Eastern and Western European nations

You included no passage but I believe the answer to be the subdivision of Christianity into different sects within Western Europe because during this period, the Catholic Church which had been the governing Christian doctrine in Western Europe, saw its authority, practices and beliefs questioned.

The Protestant Reformation marked the beginning of this period when in 1517 Martin Luther published writings that he believed would help reform the church. This work was expanded upon by John Calvin and led to the people following both the Lutheran and the Calvinist sects.

In addition, King Henry VIII of England denounced the authority of the Vatican because it would not let him annul his marriage. He replaced this with the Church of England which created another sect in Christianity. Other sects eventually followed.
