What relationship dont preposition show

It's a word that shows the relationship between a noun or a pronoun and some other word or element in the rest of the sentence. So I believe it doesn't show the relationship of a Verb.

O'Connor's neglect of the "Purple Elephant Theory of Literature" which is based around the idea that people are like purple elephants--and are thus
unique individuals and can be stipped of their social context.  However, being social creatures, social context is important--because context is key.
Context lets people know where their circumstances are, what influences that they may have, and such other things like that.
IT is important to note that though O'Connor says this, her own works sometimes strip characters of their social context and put them in situations
which are unconforatble for them, and to which they do not belong.  This is interesting, as Flannery does this against her own suggestion
