Read these lines from the poem:
I am a part of all that I have met;
Yet all experience is an arch wherethro'
Gleams that untravell'd world, whose margin fades
For ever and for ever when I move.
Which of these is an apt explanation of these lines?
Each milestone of achievement opens up a new world to be experienced.
Achievement of a goal ends the process of garnering experience.
All experience gleams through an arch in our dreams.
A sea voyage makes the horizon seem like a fading margin.
