Answer:
Step-by-step explanation:
The parallel between paragraph ten of Chapter 9 of John Steinbeck's "The Grapes of Wrath" and the opening lines of "The Battle Hymn of the Republic" suggests that Steinbeck sees the struggles of the migrant workers as a kind of holy war against the injustices of the system.
In the novel, the "armies of bitterness" refer to the disenfranchised and oppressed workers who are rising up against the landowners and corporations that exploit and mistreat them. The "vintage" symbolizes the fruits of their labor, which have been hoarded by the wealthy and powerful for their own benefit. The "wrath" is the anger and frustration of the workers who have been denied their fair share of the harvest.
The language of the Battle Hymn is used to create a sense of divine justice, as if God is on the side of the oppressed and is using them to bring about a reckoning for the sins of the powerful. The image of God's "terrible swift sword" cutting down the wicked is replaced by the more mundane but no less powerful image of the workers rising up to claim what is rightfully theirs.
Overall, the parallel suggests that Steinbeck sees the plight of the migrant workers as part of a larger struggle for social and economic justice, one that has been ongoing throughout history and will continue long after the events of the novel.
Its a little vague of a question don't know if that helped :)
