Introduction: Match the ideas in the extended metaphor with what each idea represents.
That morning there was no reason
Two roads diverged
not to choose one over the other.
The passing there had worn them
really about the same
There were two life choices to make.
And be one traveler
O O O OO
The choice looked appealing.
Both life choices were really pretty
similar.
It was grassy and wanted wear
And both that morning equally lay in
leaves no step had trodden black
The speaker could only make one
choice

The lines have been taken from the poem by Robert Frost's "The Road Not Taken" in this poem the poet talks about the choices of life that one makes and the changes that these choices bring in one's life.

Explanation:

The speaker narrates that  the woods are yellow, which indicate that it is  autumn.

The metaphorical significance is highlighted by using the term " woods" that represent the  life of the narrator.

Also the term , fork in the road is a metaphor that indicates  choices to be made. 

The narrator has come to a point in his life, where he has to make a decision,chose a path and then he is not allowed to take another path.Here the poet has made use of extended metaphor since the poem is all about making choices.

Again the  description of the road is a metaphor that indicates the future scenario of the narrators life .  When the narrator looks at the road both the roads seem to be similar (it was grassy and wanted wear) but he cannot see beyond the undergrowth, the narrator is indicating the uncertainty about the future .
