Answer:
two paths diverging in the woods
Step-by-step explanation:
According to Robert Frost's "The Road Not Taken", Frost uses the symbolism of two paths which diverge into the woods to represent a choice that the speaker must make and the uncertainty that lies behind each choice.
The symbolism of two paths leading into a forest is mostly used in narrations to show a choice a person has to make (sometimes blindly) because he does not know what lies behind each path.
