<span>Montag transforms from blind civil servant - the "fireman" who operates blindly to the directions of society to as individual who's every action is an act of civil disobedience. The act of possessing a book, taking a book from a fire, talking to the professor, reading the books and fleeing the city made him a criminal. The reader sees these acts as heroic because he is finding his "humanity". It is the act of disobedience and turning away from the societal norms -- finding something valuable in the pages of something forbidden that makes him a hero.Montag does not see himself as heroic but in memorizing the book of Ecclesiastes so as to save a piece of the past for future generations is brave and heroic act.</span>
The mood in literature is a literary element which invokes vibes and feelings through descriptions and usage of words, in the reader. Mood as a literary piece surrounds the reader by creating the emotional setting.
Therefore, mood is the emotion created by a text.
A line could be considered as a complete sentence if it both contains subject, verbs or predicate that make the whole idea in the line complete.
A Doctor (subject) + has Invented (verb) + a New Surgical Tool
So the line above could be considered as a complete sentence.
Here's a whole list of reasons/excuses:
1. The goals were unrealistic.
2. There was no breakdown of how to achieve the goals.
3. Something unexpected (an emergency) came up.
4. There were more important things to do.
5. The goals were not specific/clear enough.
6. There were too many/too hard obstacles.
Hope this helps!
