The Problem with the Kinds of Definitions of Racial Groups

The problem with the kinds of definitions of racial groups devised by 18th century Swedish naturalist Carolus Linnaeus is that,besides being ethnocentric:

A) they confuse biological traits with cultural characteristics.
B) they do not include all of the traits by which these races are distinguished.
C) they are not scientific enough;that is,they do not include the frequencies with which these characteristics occur in the population.
D) they argue that certain groups are superior to others because of their geographical location.
E) they include too many categories to be functionally useful.
