Because the rest of the choices are not environmental factors. Gang activity, and access to jobs and education are not environmental because environment are things about the world.
I think a parent's would communicate better with there kids as friends. because friends talk better with other friends because they are more open. As for kids and parent's they don't get along very well sometimes because the kid thinks the parent's are to bossy or whatever..etc.
Hope this helps
True :)))))))))) good luck
