Answer:
In "The Star" by H.G. Wells, the author uses juxtaposition to highlight the contrast between the vastness of the universe and the smallness of human beings. Juxtaposition is a literary device that involves placing two contrasting ideas, images, or themes side by side to create a stark contrast.
One example of juxtaposition in "The Star" is the comparison between the vastness of space and the smallness of the Earth. The narrator describes the star as a "great ball of fire" that is "a hundred times larger than the sun," while also emphasizing that the Earth is "a little thing, a little, forgotten thing" in comparison. This contrast highlights the insignificance of human beings in the grand scheme of the universe.
