I will provide an opinion article. I would like you to construct two trees: one is of the topics that are included within the article. This tree should include a branch for every noun or noun phrase and every predicate. It should be organized by the inferences that you are able to associate with their present usage. The other should be of the rhetorical structure of the article, and at its leaf nodes, references should be made to the topic tree. Can you work with this?
