Is there any difference between the two roads as the poet describes them
(i) in stanzas two and three?
(ii) in the last two lines of the poem?

i) In stanza two the poet explains that the only difference between the two roads was that the road he took had the right to be chosen (the better claim) because it was covered with grass and looked as if it had not been used too much. Besides this difference, both roads had been equally worn down by passersby travelling on them.
In stanza three the poet says that both the roads were equally covered with leaves and that no person had stepped on.
 ii) In the last two lines of the poem the poet says that there is a difference between the two roads because he took the road that was less travelled by other people and that made all the difference to his journey.
