A parallel sentence mentions the same grammatical expression twice. I would go with "D". 'Passed' and 'Demonstrated' are both past tense words that express the same past tense grammatical idea.
If you have more questions, feel free to ask me.
The answer is FALSE because that’s NOT for the public
A theme could be "life or death" because throughout the novel because for an example Montags wife attempts suicide until montag finds her and calls for emergency help and saves her life, and while they were trying to help her its unclear if she was going to live or die, so while all this is happening monag starts to womder what life really is.
