Which of the following is the best example of an intervening opportunity that influenced migration?
a.
many african american citizens were heading to chicago after the civil war, but settled in border cities just north of the deep south.
b.
americans from the south and the east migrated to california in search of gold in the late 1800s.
c.
some us citizens migrated to canada to avoid the draft during the vietnam war.
d.
many oil workers migrated from texas to wyoming when oil was discovered near evanston.

The correct answer is option A. "Many African American citizens were heading to Chicago after the Civil War, but settled in border cities just north of the Deep South." The theory of intervening opportunities for migration, states that migration is influenced most by the opportunities to settle at the destination, and not so much by distance or population pressure. After Civil War, African Americans tried to move to Chicago as Illinois had some of the most progressive anti-discrimination legislation in the nation. But, white hostility and population growth led African Americans to settle on the South Side of Chicago.
