Final answer:
Maggie, who is actively seeking work despite being unemployed, is included in the labor force. In contrast, Dakota and Brad, who are not looking for work, are considered 'out of the labor force' or 'not in the labor force'.
Step-by-step explanation:
In determining who is included in the labor force, we consider individuals who are either employed or actively seeking employment. Thus, among the options provided, Maggie, who is not currently employed but is actively looking for work, is considered to be part of the labor force.
On the other hand, Dakota, an unpaid homemaker not looking for other work, and Brad, a full-time student not seeking employment, are categorized as out of the labor force. It is important to understand that not all adults are included in the labor force; certain groups like retirees, homemakers, full-time students, and others who are not working and not looking for work are labeled as out of the labor force or not in the labor force.
