The reading of Sara Teasdale's poem “There Will Come Soft Rains" adds to the development of the story mainly by___

Answer is A

Explanation: this part of the poem sums it up “And not one will know of the war, not one
Will care at last when it is done.
Not one would mind, neither bird nor tree
If mankind perished utterly”
The poem is saying that we humans are not as important as we might like to think in the grand scheme of nature. If humans destroy themselves in a war, nature won't care. The birds, the frogs, and the trees will continue to go about their business as if nothing happened. The cycles of nature are more powerful than human beings.
