Although Sorting People into 'Races' by Temperament Rather Than Visible

Although sorting people into 'races' by temperament rather than visible bodily traits may seem strange, it is not uncommon cross culturally. In our text, the example provided to illustrate this involved:

A) the Lakota word for white people, which translates to 'eaters of fat' (greedy people who disregard their obligation to safeguard the environment for future generations) .
B) the Lakota word for black people, which translates to 'fat people from afar.'
C) the way that surfers classify non-surfers.
D) the Australian norm of classifying others based on what they wear on their feet.
E) Actually, sorting by temperament was explained as a very strange practice, so none of the other answers is right.
