Comparing and contrasting two novels/books are easy to do when you have a set topic. Comparing two books that involve school bullying or suicide would be easy to start with mainly because these topics are always talked about.
A prepositional phrase is a modifying phrase consisting of a preposition and its object. An example of a prepositional phrase would be something like under your hat. I think..
The correct answer would be B. Why? The direct object is David, so not that, them is not included in a prepositional phrase, so it's not an object of a preposition, and David is the subject, and not them. Hope this helps!
Have a fantabulous day! :)
I believe its C. A point in the story that shows something that happened earlier
