Separating issues, information, and contributions of certain groups from main instructional materials rather than integrating them is an example of a. cosmetic bias. b. name-calling. c. fragmentation and isolation. d. linguistic bias.

The answer is C.

Separating issues, information, and contributions of certain groups from main instructional materials rather than integrating them is an example of fragmentation and isolation. Fragmentation arises when a certain group is visually isolated in the instructional materials. Frequently, ethnic and racial groups are portrayed as cooperating merely with individuals similar to them, isolated from further other groups.
