Help on understanding piece of literature?

I think your teacher wants you to present a paper that argues two sides. One part blaming society, movies, fast food, the media, his parents for enabling a child to be obese. The other part would argue the side that he is not a victim but rather the instigator and needs to take resposibility for being obese. Some arguments to this side would be that he receives health educationa dn pe in school, the media (shows that promote health), sports activities that are available to all yount people etc. Hope that helps!
