Answer:
It sums up what the poet has written about the sun in the first three stanzas.
Explanation:
The contribution the last stanza made to the structure of "The Golden Cat" is that it sums up what the poet has written about the sun in the first three stanzas.
<em>Below is the excerpt of that stanza:</em>
<em>His face is one big Golden smile,</em>
<em>It measures round, at least a mile—</em>
<em>How dull our World would be, and flat,</em>
<em>Without the Golden Pu**y Cat.</em>
Here, the poet buttresses the point he made about the sun. He states that our world will be dull without the Golden Cat. So, it's clearly seen that this stanza sums up what have been said about the sun in the previous stanzas.
