Answer:
A. It helps create uneasiness.
Step-by-step explanation:
The text shows the imminent danger that the migrants go through. By showing that they're always lurking and finding a way of blending in to trick or even rob the migrants, you can almost feel some sort of paranoia. Gangsters are everywhere learning the behavior of migrants, using disguises and pretending to help in order to take advantage and steal some money. It certainly doesn't show any sort of trust, calmness or hope.
