Fieldsofaction Stories

In my Creative Writing class at university, the professor gave us a short ~200 word writing assignment with the following prompt: Write a short scene (200 words) in which you move back and forth between two "fields of action." By "action" I mean description of setting (background) and character (foreground), internal (thoughts of character) and external (dialogue). All four of these might be spliced with a narrative. They should work together to build a robust "scene" in which an emotion or idea is presented indirectly.
