According to a different source, this question refers to the play <em>Hamlet</em> by William Shakespeare.
There are several methods that the author employs in order to create a dramatic first scene. In Act I, scene 1, Shakespeare begins the play right at the beginning of an exciting moment. The first line asks "Who's there?" and invites the reader to pay close attention immediately.
Moreover, the first scene deals with the appearance of a ghost. Not only does this introduce a mystery (who is the ghost? why is he here?) that encourages the reader to continue reading. It also creates a scary and eerie mood that draws the reader in.
Hmm, I'm stuck between word choice and dialogue. But I think dialogue focuses more on character building, so I'd say the best answer is A. Word Choice. Hope this helps :)
