Input: Read this: Paragraph 6 of Article 29 stated that if a petition was successful a referendum should be held within three years. Since the deadline passed on 5 May 1958 without anything happening the Hesse state government filed a constitutional complaint with the Federal Constitutional Court in October 1958. The complaint was dismissed in July 1961 on the grounds that Article 29 had made the new delimitation of the federal territory an exclusively federal matter. At the same time, the Court reaffirmed the requirement for a territorial revision as a binding order to the relevant constitutional bodies.
Question: What did the Hesse state government due when the May 5, 1958 deadline passed?

Input: Read this: Charleston has one official sister city, Spoleto, Umbria, Italy. The relationship between the two cities began when Pulitzer Prize-winning Italian composer Gian Carlo Menotti selected Charleston as the city to host the American version of Spoleto's annual Festival of Two Worlds. "Looking for a city that would provide the charm of Spoleto, as well as its wealth of theaters, churches, and other performance spaces, they selected Charleston, South Carolina, as the ideal location. The historic city provided a perfect fit: intimate enough that the Festival would captivate the entire city, yet cosmopolitan enough to provide an enthusiastic audience and robust infrastructure."
Question: Who selected Charleston not to host an American version of a festival?

Output: unanswerable


Input: Read this: Criticism of the War on Terror addresses the issues, morality, efficiency, economics, and other questions surrounding the War on Terror and made against the phrase itself, calling it a misnomer. The notion of a "war" against "terrorism" has proven highly contentious, with critics charging that it has been exploited by participating governments to pursue long-standing policy/military objectives, reduce civil liberties, and infringe upon human rights. It is argued that the term war is not appropriate in this context (as in War on Drugs), since there is no identifiable enemy, and that it is unlikely international terrorism can be brought to an end by military means.
Question: Which other misnamed 'war' has 'war on terror' been compared to?

Output:
War on Drugs
