Answer:
Both quotes address the concept of borders and the concept of belonging to a country and a culture.
Step-by-step explanation:
We can see that the two sections are addressing the concept of country, border and territory, because in both we can see that the speaker is separating the territories between the USA and Canada. The second excerpt goes so far as to address the question of belonging, of cultural recognition, when asking someone whose side this person is on.
These concepts are directly related to the story of "Borders" that presents a Native American woman who refuses to recognize herself as a Canadian or American citizen, since the tribe where her people lived and the lands that were theirs, was stolen and it ceased to exist to give rise to the Canadian and American territories, to which this woman does not identify.
