Answer with Explanation:
Nancy Mairs described herself as the "Ms. Great American Consumer" because she felt that she was just like the other ordinary women who buys products being advertised due to several things. For example, she buys tampons during menstruation, buys mouthwash, puts lotion on her skin, drives a car, eats pizza and so on. Advertisers would totally love the idea of a person who adores their products or uses their products like ordinary people do.
So, Mairs just couldn't understand why, somehow, disabled people (who are great consumers) are not being included in the advertisements.
