Human Trafficking is the act of recruiting or abducting people (usually children and teens) and doing...let's just say bad things to them. Some things could involve sexual acts, forcing them into labor, and even torturing them (like removing their organs or just doing it for fun).
People usually do this to gain money from it, which gets them a lot. In easier words, Human Trafficking is illegal and slavery.

The media's ability to determine what people know about their government is called selection bias (A).
Selection bias is the result of a medium's abiliy to restrict how much or which data it considers and publishes. The information released to the public is therefore biased in the sense that since it lacks randomization and variety, the subject of the information (in this case, the government) is not depicted in a representative way.
