describe (in words) two different sets of people containing you as a member. describe (in words) the complement of each set. describe what people are not in either the orininal set or the complement set
You might think of various categories that include you — gender, age group, religious group, racial/ethnic group, school group, kinship group, sports team and so on. Pick two of these that are most familiar to you and compare them.
I hope this helps. Thanks for asking.
