Answer:
In 1930, Atticus delivers his final argument to try to convince the jury that Tom Robbinson is inocent.
A few words that may be harder to understand are:
Iota: "an infinitesimal amount"
Used in the argument as:
"...The state has not produced one iota of medical evidence..."
Where he wanted to say that the state practically didn't find any evidence against Tom Robbinson.
Pauper: "A very poor person"
Used as:
"...There is one human institution that makes a pauper the equal of a Rockefeller..."
Where he wanted to say that this institution (the court) should judge in the same way a poor person than a rich person.
Time-honored: "A tradition respected because it has existed for a long time" (I know that this is a composite word)
Used in the argument as:
"...She has merely broken a rigid and time-honored code..."
Where he wanted to say that Mayela Ewell wanted to hide her "offence" by accusing Tom.
