Answer: a person does not have access to their ID.
Step-by-step explanation:
When a person is being trafficked, the traffickers try to make sure that the person is stranded with them and has no place to go and even if they had a place, could not go there.
One of the best ways to do this is by taking away their identification documents such as their ID cards. Without an a valid ID, most services in the world today are denied. In taking way their IDs therefore, they ensure that the person cannot access services such as transport and healthcare for instance. This will ensure that the person relies on the trafficker for everything and won't try to escape.
