I was able to narrow down to B and E. I know B is supported by L16-18.
But I couldn't figure out why E is wrong.
It seems to me, the functions of proverbs as inculcation of table manners and regulation of peer-group relationships both serve as educational purposes.
can anyone explain?
Or does the passage suggest that the purpose is not both of table manners and peer-group relationships, but E means one proverb serves both purposes, which is not correct?
