This task is about creating an unanswerable question based on a given passage. Construct a question that looks relevant to the given context but is unanswerable. Following are a few suggestions about how to create unanswerable questions:
(i) create questions which require satisfying a constraint that is not mentioned in the passage
(ii) create questions which require information beyond what is provided in the passage in order to answer
(iii) replace an existing entity, number, date mentioned in the passage with other entity, number, date and use it in the question
(iv) create a question which is answerable from the passage and then replace one or two words by their antonyms or insert/remove negation words to make it unanswerable.

Input: Consider Input: Passage: Hoover began using wiretapping in the 1920s during Prohibition to arrest bootleggers. In the 1927 case Olmstead v. United States, in which a bootlegger was caught through telephone tapping, the United States Supreme Court ruled that FBI wiretaps did not violate the Fourth Amendment as unlawful search and seizure, as long as the FBI did not break into a person's home to complete the tapping. After Prohibition's repeal, Congress passed the Communications Act of 1934, which outlawed non-consensual phone tapping, but allowed bugging. In the 1939 case Nardone v. United States, the court ruled that due to the 1934 law, evidence the FBI obtained by phone tapping was inadmissible in court. After the 1967 case Katz v. United States overturned the 1927 case that had allowed bugging, Congress passed the Omnibus Crime Control Act, allowing public authorities to tap telephones during investigations as long as they obtain a warrant beforehand.

Output: When did Hoover stop using wiretapping?

Input: Consider Input: Passage: Cubism and modern European art was introduced into the United States at the now legendary 1913 Armory Show in New York City, which then traveled to Chicago and Boston. In the Armory show Pablo Picasso exhibited La Femme au pot de moutarde (1910), the sculpture Head of a Woman (Fernande) (190910), Les Arbres (1907) amongst other cubist works. Jacques Villon exhibited seven important and large drypoints, his brother Marcel Duchamp shocked the American public with his painting Nude Descending a Staircase, No. 2 (1912). Francis Picabia exhibited his abstractions La Danse a la source and La Procession, Seville (both of 1912). Albert Gleizes exhibited La Femme aux phlox (1910) and L'Homme au balcon (1912), two highly stylized and faceted cubist works. Georges Braque, Fernand Leger, Raymond Duchamp-Villon, Roger de La Fresnaye and Alexander Archipenko also contributed examples of their cubist works.

Output: What was the name of the show that introduced Cubism to China?

Input: Consider Input: Passage: Whitehead also described religion more technically as "an ultimate craving to infuse into the insistent particularity of emotion that non-temporal generality which primarily belongs to conceptual thought alone." In other words, religion takes deeply felt emotions and contextualizes them within a system of general truths about the world, helping people to identify their wider meaning and significance. For Whitehead, religion served as a kind of bridge between philosophy and the emotions and purposes of a particular society. It is the task of religion to make philosophy applicable to the everyday lives of ordinary people.
Output: What was Whitehead's technical definition of nonreligion?
