Brooke's family consists of her biological mother, biological sister, and step-father. this kind of unit is known as

Blended family

Explanation:

The family is one of the most important institutions of society and it has, over time, undergone several transformations, changing its meaning according to the environment and the historical moment in which it finds itself. All these transformations gave rise to many different types of family. An example of these types is the blended family, which was shown in the question above.

Blended family happens when parents who have children break up, and eventually start living with someone else who may have children in other relationships or not. In this case, some family members are biologically members of the same family, while other members are not. The family shown in the above question shows a mother, two daughters and a stepfather. The stepfather is not biologically a family member, so this is a blended family.

panem is a communist totalitarian dictatorship where all the resources and how they are allocated belongs to the capitol. the districts exist only to provide goods and services for the capital and most of the citizens live in poverty. it is a police state where the "peacekeepers" use force and threats to keep the people under control. dissent is outlawed and those who disobey the law are executed, flogged, or turned into avoxes. the games are another means in which the ruling elite in the capitol exert their power over the districts. when reading the books i drew parallels between panem and the soviet union and north korea. in no way is panem capitalist. the people in the capitol are wealthy but the majority of them are involved in the government somehow. it was the same way in the former soviet union where bigwigs in the communist party and high ranking government officials were given access to goods, services, medical treatments not available to the general public. if you think panem has a capitalist economy you need to brush up on your economics.
