What aspect of culture does the following excerpt from "what for" by garrett hongo celebrate?

"i lived for stories about the war
my grandfather told over hana cards,
slapping them down on the mats
with a sharp japanese kiai."
a. holidays
b. religion
c. family
d. cuisine

the correct answer is the first option "the bolkshevik revolution". the passage makes reference to many of important events that occured in the revolution, such as the assemblies, in this case the animals are gathered in an assembly after a protest, the murder of fellow partners, the speeches given by the leader of the revolution, among other aspects. the last choice is possible, but in this passage in particular it is not emphasized the fight between the characters, that is the two pigs, that represent lenin and stallin.
