The text does not provide any definitions, thus, options a. definition-example and cause-effect and c. comparison-contrast and definition-example can be out ruled...There are provided examples just not definitions. The text does show patterns of cause and effect--such can be shown with sentence (6) "Clearly the feeling of being anonymous causes people to engage in antisocial behavior." This sentence shows that the cause (anonymity) can lead to the effect (antisocial behavior). Hence, the correct option is b. cause-effect and comparison-contrast.
Internalized racism is the belief among historically oppressed people that stereotypes about themselves are true.
Black and Latino/a then follow through with this subjugation based on the ideology that the oppressor has stereotypically positive qualities and they themselves are not equal or inferior. Black and Latino/as would also suppress their own identities and cultures to conform to Eurocentric standards.
