Achallenge that mexican citizens living in areas that were part of the mexican cession faced was that
a. they were separated from white settlers.
b. their families were forced into slavery.
c. they did not know how to farm.
d. their families lived in mexico and the us.

The correct answer is D) their families lived in Mexico and the U.S.

One of the challenges that Mexican citizens living in areas that were part of the Mexican cession faced was that their families lived in Mexico and the U.S.

Living in a territory that formerly belonged to one country and then it changed hands to another country, was a difficult situation Mexican citizens had to face after the cession of territories to the United States. They were used to live under one culture and tradition, very different than the ones in the United States. After the cession, families needed to adapt to new ways of living and new laws.
