Step-by-step explanation:
Social inequality can be perceived in this scenario in the fact that Reggie's family and school are more affluent than the other kids and school, reason why Reggie made fun of their uniforms. There is also categorization here, as they categorizaed the other team for their uniforms and made fun of them, is the act of putting things in order, in groups, and this is what they did. Finally, there is no in-group bias or favoritism, form of prejudice here, as this one refers to have to favor your own group above than the others. The fact of blaming everything to the boy who missed the shot, implies a lack of this.
