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.

Passage: This was also a period of alternatives to nightclubs, the warehouse party, acid house, rave and outdoor festival scenes of the late 1980s and early 1990s were havens for the latest trends in electronic dance music, especially house and its ever-more hypnotic, synthetic offspring techno and trance, in clubs like the infamous Warsaw Ballroom better known as Warsaw and The Mix where DJs like david padilla (who was the resident DJ for both) and radio. The new sound fed back into mainstream clubs across the country. The scene in SoBe, along with a bustling secondhand market for electronic instruments and turntables, had a strong democratizing effect, offering amateur, "bedroom" DJs the opportunity to become proficient and popular as both music players and producers, regardless of the whims of the professional music and club industries. Some of these notable DJs are John Benetiz (better known as JellyBean Benetiz), Danny Tenaglia, and David Padilla.
Who was the Warsaw Ballroom's house JD?

Passage: During the Middle Ages, Thuringia was situated at the border between Germanic and Slavic territories, marked by the Saale river. The Ostsiedlung movement led to the assimilation of Slavic people between the 11th and the 13th century under German rule. The population growth increased during the 18th century and stayed high until World War I, before it slowed within the 20th century and changed to a decline since 1990. Since the beginning of Urbanisation around 1840, the Thuringian cities have higher growth rates resp. smaller rates of decline than rural areas (many villages lost half of their population since 1950, whereas the biggest cities (Erfurt and Jena) keep growing).
Where was Thuringia attacking in the Middle Ages?

Passage: To measure the difficulty of solving a computational problem, one may wish to see how much time the best algorithm requires to solve the problem. However, the running time may, in general, depend on the instance. In particular, larger instances will require more time to solve. Thus the time required to solve a problem (or the space required, or any measure of complexity) is calculated as a function of the size of the instance. This is usually taken to be the size of the input in bits. Complexity theory is interested in how algorithms scale with an increase in the input size. For instance, in the problem of finding whether a graph is connected, how much more time does it take to solve a problem for a graph with 2n vertices compared to the time taken for a graph with n vertices?
How does one measure the simplicity of a computational problem?
