The evidence from the passage that supports the author's explicit statement that many Native Americans on tribal reservations do not have standard addresses is:
A. “‘They’ll say something like, I live off highway 86 by milepost 125 and a half,’ said Gabriella Cázares-Kelly, a member of the Tohono O’odham Nation and a Democratic candidate for Pima County recorder in Arizona.”
This statement illustrates how Native Americans on tribal reservations often describe their locations in nontraditional terms, highlighting the absence of standard addresses.
