Answer:
the fourth one, what happened and to whom?
This is an adequate subject because there is no surplus of information or anything that can be removed.
I don't know exactly what the question is to "which best describes the effect of the narration" But I would assume we have to pick a certain line within the passage, and with that I would have to go with the opening paragraph since it gives such deep and thoughtful descriptions.
I think its : The place they are taking Bob to is beautiful!!
