Final answer:
The provided excerpts do not directly answer why Snyder had to give up control of the gun; additional context from 'Take Over, Bos'n!' is needed to explain the specific circumstances leading to this event.
Step-by-step explanation:
In the excerpt from 'Take Over, Bos'n!', Snyder had to give up control of the gun due to a confrontational and intense situation with a character named Jane, indicating a power struggle and possibly a moment of realization or defeat. However, the provided text does not contain sufficient information to determine the exact reasons for this specific action.
The narrative seems to revolve around themes of power, control, and possibly surrender, reflecting the complexities of the characters' interactions. To determine why Snyder had to relinquish control of the gun, more context from the book would be necessary.
