12. Rhea claims that the concept of race is socially constructed and does not actually
contribute to the economic and social success that one attains. Which of the following
statements supports her claim?
a. All research shows that the alleged differences between group averages are much greater
than the differences within a group.
b. It is not possible to generalize about absolute differences between groups in terms of
intelligence because intermarriages have made such generalizations difficult.
c. Similar to the fact that people differ in temperament, potential to learn, and sense of humor,
among other characteristics, people who differ physically also bear distinctive emotional and
mental abilities or disabilities.
