Question

find the appositive. if it is nonrestrictive, set it off with commas. if it is restrictive, submit the text without making any changes. henry david thoreau built his famous one-room cabin on land owned by the transcendentalist poet ralph waldo emerson.

Explanation:

The appositive here is "Ralph Waldo Emerson", which identifies the specific transcendentalist poet. Since there is only one well-known transcendentalist poet associated with Thoreau in this context, this is a nonrestrictive appositive that needs commas to set it off, as it provides extra, non-essential information.

Answer:

Henry David Thoreau built his famous one-room cabin on land owned by the transcendentalist poet, Ralph Waldo Emerson.
