a.) give key information
b.) state the purpose
c.) introduce themselves
d.) pose questions

Authors use titles to state the purpose :)
Hope this helps :D

I Think The Answer Is B.state the purpose please choose brainiest.

The correct answer is d

A. they give the reader hope. if the whole book was dark & unhopeful it’d be a little less interesting, little moments make it more interesting to read because then you want to know what happens. if it’s all dark there’s no point in reading if you already know the outcome of it.
