A foil is a character that has qualities or characteristics that are in direct contrast
with the qualities or characteristics of the protagonist. Foils often exist so that the
protagonist's flaws are more obvious and can be better understood.
In Act IV of Hamlet, two foils emerge. Who are they? Why are these two
characters foils of Hamlet? How are they Hamlet's foils? Please quote three
specific places in the play to illustrate how these two characters are foils. Two of
these places in the play should explain how / why the two are foils, and the third
place should show the contrasting characteristic in Hamlet (doesn't have to come
from Act IV only).
