Review the poem "summer."
the speaker claims that others find "sympathy which spurs them on to any great endeavor."
which line best explains what the speaker gains from nature?
the very crown of nature's changing year
and it is summer, glorious, deep-toned summer
when all her surging life is at its full
gathering strength for efforts yet to come

In the poem "Summer," the line that best explains what the speaker gains from nature is, "gathering strength for efforts yet to come."

The line that would support this statement would have to show how the speaker would benifit from nature. The other lines explain the glorious beauty of the nature like how it changes, the color, and how it is full of life. However, they do not best explain what the speaker gains from nature, which is strength.
