Question

choose the poem that uses repetition.
i see the tracks of the railroads of the earth;
i see them welding state to state, city to city,
through north america,
i see them in great britain, i see them in europe;
i see them in asia and in africa.

the lonely bridge cuts dark across the marsh
whose long pools glow with the light
of a flaming summer sunset.
at this end limp bushes overhang,
palely reflected in the amber - colored water.

Explanation:

The right poem uses the repetitive phrase "I see them" (and opens with "I see the tracks") across its lines, which is clear repetition. The left poem has no repeated sentence structures or phrases.

Answer:

The poem on the right:
I see the tracks of the railroads of the earth;
I see them welding State to State, city to city, through North America;
I see them in Great Britain, I see them in Europe;
I see them in Asia and in Africa.
