(i) Which of the two roads did the poet take?
(ii) Which road according to the poet, had the better claim?
(iii) Which phrase in the stanza means ‘had not been used so frequently’?
The phrase 'had not been used so frequently' means that travellers didnot use the road (i.e. Profession). Therefore they used the first road as profession not choosing the other one. And the poet chooses the second road for profession that is not worned by the travellers.
