I understand the just of this poem, but I need help with these three questions. It would be greatly appreciated 
2. What was the economic status of the parents of Warren Pryor?
3. Quote two passages from the poem, which indicate the economic status of the family.
8. What is the significance of the son wearing a white shirt on workdays and jeans on Sunday?
Warren Pryor
by Alden Nowlan
When every pencil meant a sacrifice
his parents boarded him at school in town,
slaving to free him from the stony fields,
the meagre acreage that bore them down.
They blushed with pride when, at his graduation,
they watched him picking up the slender scroll,
his passport from the years of brutal toil
and lonely patience in a barren hole.
When he went in the Bank their cups ran over.
They marvelled how he wore a milk-white shirt
work days and jeans on Sundays. He was saved
from their thistle-strewn farm and its red dirt.
And he said nothing. Hard and serious
like a young bear inside his teller's cage,
his axe-hewn hands upon the paper bills
aching with empty strength and throttled rage.
