Why is race considered a "social construct? " race is a scientific way of grouping different types of people based on skin color or physical features. the scientific basis for racial difference rests on shaky ground, but is still accurate over half the time. physical variations in the human species have no meaning except the social ones that humans put on them. an increase in interracial marriages and children born of these marriages has given rise to new classifications?

The correct answer is the third option: physical variations in the human species have no meaning except the social ones that humans put on them.

Race is a social construct because factors such as beliefs, biases and prejudices that are prevalent in society lead generations of individuals to form beliefs about members of certain races. From a sociological perspective, while individuals belonging to different races might have variations in physical appearance, they do not have any other "real" differences. All the perceived differences across races are socially constructed.
