Hello. The lines you are referring to contain the following information:
<em>"Frozen branches heavy
</em>
<em>with ice arms Couldn't
</em>
<em>perform their dance "</em>
Answer:
Personification
Explanation:
Personification is the figure of speech that allows inanimate or non-human objects to have human characteristics. In the lines indicated in the question above, we can see that the author decided to present the sadness that the frozen branches have, since the ice forbids them to dance.
Dancing is a human characteristic, however, the branches are not human. By placing this characteristic on the branches, the author adds a tone of hopelessness, because the desire of the branches cannot be fulfilled.
