Final answer:
Sam and Andy aid Eliza's escape in Uncle Tom's Cabin by causing distractions and delays for the slave catchers, giving her time to get away with her child.
Step-by-step explanation:
In the context of Uncle Tom's Cabin, Sam and Andy buy Eliza time to escape by creating confusion and delay. This incident refers to a chase scene where Eliza, a slave mother, is running away to save her child from being sold. Sam and Andy, slaves from the same plantation, create distractions to slow down the slave catchers, thus providing Eliza with precious moments to widen the gap between her and her pursuers.
The deliberate misdirection and sabotaging of their master's efforts to capture Eliza highlight the resourcefulness and covert resistance of the slaves within the narrative. Their actions directly contribute to buying Eliza time, an act of solidarity and covert defiance against the brutal system of slavery depicted in the novel.
