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: The innovative production techniques devised by post-punk producers such as Martin Hannett and Dennis Bovell during this period would become an important element of the emerging music, with studio experimentation taking a central role. A variety of groups that predated punk, such as Cabaret Voltaire and Throbbing Gristle, experimented with crude production techniques and electronic instruments in tandem with performance art methods and influence from transgressive literature, ultimately helping to pioneer industrial music. Throbbing Gristle's independent label Industrial Records would become a hub for this scene and provide it with its namesake.

Output: Who avoided post-punk production?

Input: Consider Input: Passage: Traditionally, Section 1983 was of limited use for a state prisoner under sentence of death because the Supreme Court has held that habeas corpus, not Section 1983, is the only vehicle by which a state prisoner can challenge his judgment of death. In the 2006 Hill v. McDonough case, however, the United States Supreme Court approved the use of Section 1983 as a vehicle for challenging a state's method of execution as cruel and unusual punishment in violation of the Eighth Amendment. The theory is that a prisoner bringing such a challenge is not attacking directly his judgment of death, but rather the means by which that the judgment will be carried out. Therefore, the Supreme Court held in the Hill case that a prisoner can use Section 1983 rather than habeas corpus to bring the lawsuit. Yet, as Clarence Hill's own case shows, lower federal courts have often refused to hear suits challenging methods of execution on the ground that the prisoner brought the claim too late and only for the purposes of delay. Further, the Court's decision in Baze v. Rees, upholding a lethal injection method used by many states, has drastically narrowed the opportunity for relief through Section 1983.

Output: n what case did the Supreme Court allow Section 1989 to be used to challenge a method of execution?

Input: Consider Input: Passage: While BSkyB had been excluded from being a part of the ONdigital consortium, thereby making them a competitor by default, BSkyB was able to join ITV Digital's free-to-air replacement, Freeview, in which it holds an equal stake with the BBC, ITV, Channel 4 and National Grid Wireless. Prior to October 2005, three BSkyB channels were available on this platform: Sky News, Sky Three, and Sky Sports News. Initially BSkyB provided Sky Travel to the service. However, this was replaced by Sky Three on 31 October 2005, which was itself later re-branded as 'Pick TV' in 2011.
Output: What consortium was BSkyB included with?
