Your genes determine your skin's color, but for centuries, humans have tried to lighten or darken their skin in an attempt to be more attractive. In the 1800s, white skin was desirable for many Europeans. Skin this color meant that its owner was a member of the upper class and did not have to work in the sun. Among darker-skinned people in some parts of the world, products used to lighten skin are still popular today. During the 20th century, attitudes toward light skin shifted in the opposite direction in other cultures, as cities grew and work moved indoors. Tanned skin began to indicate leisure time and health. In many places today, tanning on the beach or in a salon remains popular, even though people are more aware of the dangers of UV rays.What is the purpose of paragraph B?
