To Build a Fire - the story of the famous American writer Jack London; popular version was published in 1908.This story is a prime example of the conflict between man and nature. Jack London reflected in the story of his own life in the Yukon Territory.
The protagonist travels through one of the trails of the Yukon in a very cold day (-75 ° F / -59 ° C), accompanied by a dog. He goes on the trail along the creek, conscious of the danger of natural traps that are generated by mining underground streams, because in such a wet cold would have meant certain death. Continuing the way, the traveler sinks knee-deep in water.
The issues would be that people want to change others cultures and, like in the Aztec culture (when there was Aztecs),the religion is too harsh and you were killed if you didn't accept their culture. <span />
I believe the best antonym for lucid is confused!
Hope this helps!
