You could read a conflict into almost any story if you want to, the difference being that it'd be more of a stretch in some cases. At a 7th grade level the goal of the class was probably to teach you to find a conflict-being able to say "there isn't one!" would be an easy out that would let you get away with not writing an essay. Similarly, early math classes won't have questions for which "no solution" is a valid answer, but later ones will.
