In "The Skater of Ghost Lake" by William Rose Benét, the best answer choice that correctly explains how the poet's diction affects the meaning of the stanzas is:
the emphasis on the darkness of the lake and the presence of a mysterious shadow make the lake seem dangerous.
This choice highlights the evocative language used to create a mood of danger and foreboding, suggesting that the lake is not just a simple natural feature, but carries an air of peril and mystery. The portrayal of the lake's darkness and shadows contributes to an atmosphere that can evoke feelings of unease, which is central to understanding the poem's themes and emotional impact.
