Question

Which of the following helped make Christianity a major world religion?

A-The conversion of Emperor Constantine

B-The conquest of Mongol Empire

C- The attractiveness of polytheism

D-The trade between the African and Islamic Empire

Answer 1

The correct answer is A. the conversion of Emperor Constantine.
It's not B or D because the Mongols, Africans, or Muslims, don't have much to do with Christianity. C is definitely incorrect because Christianity is not a polytheistic religion.
This means the correct answer is A, because when Constantine converted to Christianity, he wanted to spread the new religion everywhere.
