Which details from The Omnivore's Dilemma Part 1 indicate that corn was once used as an important tool for trade

you may need to add a question, yeah?

ismene wants to follow the rules, unlike antigone who'd rather break them for her brother.

faithful servants eumaeus and philaetius:

his ragged vest then drawn aside disclosed the sign conspicuous, and the scar exposed: eager they view'd, with joy they stood amazed with tearful eyes o'er all their master gazed:

these servants know ulysses by the scar he got when he was a child - so when he showed them the mark, they immediately knew this is truly their master and they hugged him, finally starting to believe his words.

this question is not school related. refrain from asking non school or academic related questions in the future.
