Which best explains how the words "foe" and "demon" affect the mood of "can't"? they create a sense of shock and relief. they create a sense of comfort and relief. they suggest companionship and joy. they suggest tension and possible struggle.

The answer should be D because "demon, foe, can't"  are not comforting word, nor is it a relief or joyful. 

This was already the answer "the use of academic language creates an angry and disdainful tone. the use of academic language gives the text a serious and instructive tone. the use of words with strong connotative meanings creates a sorrowful tone."
