This is an example of a fragment because it isn't an independent clause and so, it cannot stand on its own. In other words, if it is not attached to a main clause, it doesn't make sense. It could be a sentence, if it was joined to a main clause. <u>For example:</u> <em>We didn't know whether he came up from dark, fog-filled forest. </em>
I have no I deal what this is about because I have never read the article but I'm leaning towards A , B or C and then out of those 3 just see which one matches the perspective more because I haven't read the article so I can't really say an answer...I'm sorry I tired at least but have a nice day or afternoon or night where ever you are
