The correct answer to this open question is the following.
Although there are no options attached, we can say the following.
The idea associated with Enlightenment that revealed a rational or logical approach to religion was the idea that the world can be best understood by the use of reason and the human brain, instead of "blindly" believing in the religious precepts of the church. That is why Enlightenment is also called the Age of Reason. Through observation and the use of reason, humans could better explain the natural phenomenon that previously was explained by religious and mystic concepts.
