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.

[Q]: Passage: A new generation of clubs such as Liverpool's Cream and the Ministry of Sound were opened to provide a venue for more commercial sounds. Major record companies began to open "superclubs" promoting their own acts. These superclubs entered into sponsorship deals initially with fast food, soft drinks, and clothing companies. Flyers in clubs in Ibiza often sported many corporate logos. A new subgenre, Chicago hard house, was developed by DJs such as Bad Boy Bill, DJ Lynnwood, DJ Irene, Richard "Humpty" Vission and DJ Enrie, mixing elements of Chicago house, funky house and hard house together. Additionally, Producers such as George Centeno, Darren Ramirez, and Martin O. Cairo would develop the Los Angeles Hard House sound. Similar to gabber or hardcore techno from the Netherlands, this sound was often associated with the "rebel" culture of the time. These 3 producers are often considered "ahead of their time" since many of the sounds they engineered during the late 20th century became more prominent during the 21st century.
[A]: Where was a new type of club called Darren Located?


[Q]: Passage: In the former Soviet Union, electric traction eventually became somewhat more energy-efficient than diesel. Partly due to inefficient generation of electricity in the USSR (only 20.8% thermal efficiency in 1950 vs. 36.2% in 1975), in 1950 diesel traction was about twice as energy efficient as electric traction (in terms of net tonne-km of freight per kg of fuel). But as efficiency of electricity generation (and thus of electric traction) improved, by about 1965 electric railways became more efficient than diesel. After the mid 1970s electrics used about 25% less fuel per ton-km. However diesels were mainly used on single track lines with a fair amount of traffic  so that the lower fuel consumption of electrics may be in part due to better operating conditions on electrified lines (such as double tracking) rather than inherent energy efficiency. Nevertheless, the cost of diesel fuel was about 1.5 times more (per unit of heat energy content) than that of the fuel used in electric power plants (that generated electricity), thus making electric railways even more energy-cost effective.
[A]: In the US, electric traction became more energy-efficient than what?


[Q]: Passage: Many early immigrant groups traveled to America to worship freely, particularly after the English Civil War and religious conflict in France and Germany. They included nonconformists like the Puritans, who were Protestant Christians fleeing religious persecution from the Anglican King of England. Despite a common background, the groups' views on religious toleration were mixed. While some such as Roger Williams of Rhode Island and William Penn of Pennsylvania ensured the protection of religious minorities within their colonies, others like the Plymouth Colony and Massachusetts Bay Colony had established churches. The Dutch colony of New Netherland established the Dutch Reformed Church and outlawed all other worship, though enforcement was sparse. Religious conformity was desired partly for financial reasons: the established Church was responsible for poverty relief, putting dissenting churches at a significant disadvantage.
[A]:
What was one of the reason late immigrant groups came to America?
