Passage Summary: If everyone just makes up their own meaning for a poem, we can't objectively judge it, because judging it requires people to agree on what it actually means.

Conclusion: Objective evaluation of poetry is only possible if the belief that readers determine meaning is false.

Reasoning: Discussing a poem's aesthetic value requires that at least two readers can agree on a single correct interpretation.

Analysis: The argument relies on a conditional chain: objective evaluation requires aesthetic discussion, which in turn requires the possibility of agreement on interpretation. The 'gap' is the assumption that the popular belief (that meaning is subjective) makes such agreement impossible. Look for an answer that connects the ability to have an objective evaluation to the necessity of discussing aesthetic value. The argument 'needs' it to be true that objective evaluation cannot happen without these discussions.
