Answer:
The best answer to your question: One theme of the poem is:___, would be B: people and animals are not so different after all.
Explanation:
"At the Aquarium" is short poem that was written by American poet and philosopher Max Eastman and which was later on published in the Modern American Poetry in 1919.
Although the poem may have other themes, one that really comes to the forefront of the whole thing is the comparisson that arises, or rather the similarity that arises, between the fish in the aquarium, who are being stared at by people, and the people themselves, whose activities seem to be no different, their actions and reactions also, to those of the fish. For example, at first the speaker tells us that the fish "they watch with staring, cold surprise..." then, the poet also says about people: " Yet have a wonder in their eyes, Sometimes a pale and cold surprise." Another similarity that appears in the poem and that shows that people and animals are not so different after all is when both species are said to be wondering around, without a clear path, or without knowing where they are going; only that both are moving back and forth, both in a "to and fro" motion.
