Answer:
This allusion expresses the poem's meaning in the following way:
It cautions that slavery doesn’t just destroy the slave, but also destroys American ideals.
Step-by-step explanation:
The poem and the analysis are focused on slavery. So, if we analyze all off the options the second one says that slaves could destroy the country. But, slaves don' have enough power to destroy the country. Also, there is no certainty that a released slave would kill people it is just a belief. In our case, Samson is a metaphorical figure, not a literal example. The third option is incorrect because slavery is not allowed anymore. the fourth case is incorrect because slaves were not a bigger part of the population to use their vote and change the country. They were almost 5 or 6% of the total population in their last moments of slavery. Therefore option A is correct because it was a metaphor to say that slaves were a big force that destroyed American ideals
