Hi, before we look at the answers, let's remember that the author did seem generally supportive of the downstate campaign.
A is not stated in the passage. We don't really know if they were altered. B is directly contradicted by the passage. No new legislation was passed. C does appear in the passage, but the author appears neutral about the relationship. D is supported in the last paragraph. The two sentences starting at line 53 show that the author seems warmly disposed to how the campaign impacted public opinion and awareness. E is not supported since we know little about the way in which the negotiations actually played out.
