color?
A. As moral: People of color were often portrayed as being more
honest than whites.
B. As educated: People of color were often portrayed as being more
educated than whites.
C. As cognitive: People of color were often portrayed as having
higher values than whites.
o
D. As imitated: People of color were often played by whites made up
to look like people of color.

Answers

Answer:

D

Explanation:

Method of elimination. POC have never been portrayed as better than whites in any sense. Not as "more honest", not as "more educated", and not as "having higher values than whites". A specific example of imitation can be Jim Crow, who dressed in blackface for white entertainment.

A major way that media have historically represented people of color is as imitated. People of color were often played by whites made up to look like people of color. Thus, the correct answer is option D.

What is media?

Media refers to various forms of communication that are used to transmit information and messages to large groups of people. This includes television, radio, newspapers, magazines, social media, and other digital platforms.

Throughout much of history, people of color have been poorly represented in the media, often being portrayed in offensive and stereotypical ways. One of the most common ways in which they have been represented is through the use of blackface or other forms of makeup to make white actors look like people of color.

Therefore, a major way that media have historically represented people of color is as imitated. People of color were often played by whites made up to look like people of color. Thus, the correct answer is option D.
