Final answer:
The excerpts provided do not correlate with the situation from 'Of Mice and Men' by John Steinbeck, and without relevant context, it is not possible to accurately answer why George does not help Lennie in a fight.
Step-by-step explanation:
It appears that the context of George not helping Lennie in a fight refers to a misinterpretation of various narrative extracts, none of which directly relate to the original characters of George and Lennie from John Steinbeck's 'Of Mice and Men'. The extracts included seem to be from different stories and do not provide a definitive answer to why George does not help Lennie in a fight. In literature, characters may not assist one another due to a variety of reasons such as fear, incapacitation, or a plot-driven requirement for a character to face a challenge alone. Understanding the motives of characters often requires analysis of the text and the circumstances presented within it. Therefore, without a specific context from Steinbeck's work or another identifiable narrative, an accurate reason can not be determined.
