Answer: Her situation is an example of MODERN SLAVERY
Step-by-step explanation:
Slavery is a system or condition that includes forced labour wherein individuals are acquired like properties and kept against their wills without the freedom to make their own decisions.
It is important to state that slavery did not completely end after it was abolished in the 19th century, rather it sort of changed its form and today; it remains a huge problem in virtually every country given the form it has now taken.
Modern slavery can take the form of forcing women to engage in sexual acts against their will for monetary rewards, it can involve forcing children who are supposed to be in school to become food/fruit vendors. Modern slavery can entail forcing girls to marry much older men or coercing individuals to work on construction sites. In these cases, the individuals do not have choices but must do the will and execute the orders of their exploiters.
The new form slavery took is "modern exploitation" where people can seem or appear to be free but are still very much being exploited and controlled without a choice to quit or leave.
So, in the case of the young girl from a poor family who was sent to live with a wealthy distant relation. It is obvious that this girl has now been turned into a modern day slave since she is forced to do all house chores, despite this, she is never paid for all her services and still get threatened whenever she attempts returning home.
She is being forced through coercion, threat and manipulation to continue doing their bidding without a choice to opt out. This is therefore a case of MODERN SLAVERY
