Answer:
"Vostok's capsule clambers / Up the tall victory column."
Step-by-step explanation:
Themes give larger meaning to the main idea in a work of literature. The main idea is specific to the story, but a theme can be applied to one's own life or experiences. Sometimes, a work of literature can contain more than one theme. It might be helpful to think of a theme as a "deeper meaning" in a piece of literature. The poet also expresses the overall theme of this poem in the lines, "Vostok's capsule clambers /Up the tall victory column." These lines bear a similar meaning to the lines from the question.
