On Iowa

Holston was attempting to discover what the impact of the film "Napoleon Dynamite" was having on the people living where it was filmed. Her questions were focused on finding the impact of an event(Filming of and release of the film) had on the small town. More importantly the ways in which the townspeople's lives had changed since the movie was a Hollywood hit. She spoke to everyone, In person it seems(no mention of electronic media mentioned and quotes common). The man who shot the cow, the people dressed up for the towns look alike contest, and the chamber of commerce to list a few.

I would say option C. She is using the opinions of the local Iowa town to demonstrate what happens when an event like this (Napoleon Dynamite) occurs.She examines the Social structure more than anything else, explaining both sides. Those who are glad that the town is getting some popularity and those who fear that it will be a seen as a hick town. Indeed she showed that for better or worse the town had changed since the film.
