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: In the early years, Universal had a "clean picture" policy. However, by April 1927, Carl Laemmle considered this to be a mistake as "unclean pictures" from other studios were generating more profit while Universal was losing money.

Output: What policy was established in April 1927?


Input: Consider Input: Passage: The most-commonly accepted theory is that these events were triggered by the onset of an ice age, in the Hirnantian faunal stage that ended the long, stable greenhouse conditions typical of the Ordovician. The ice age was probably not as long-lasting as once thought; study of oxygen isotopes in fossil brachiopods shows that it was probably no longer than 0.5 to 1.5 million years. The event was preceded by a fall in atmospheric carbon dioxide (from 7000ppm to 4400ppm) which selectively affected the shallow seas where most organisms lived. As the southern supercontinent Gondwana drifted over the South Pole, ice caps formed on it. Evidence of these ice caps have been detected in Upper Ordovician rock strata of North Africa and then-adjacent northeastern South America, which were south-polar locations at the time.

Output: What faunel stage triggered the greenhouse conditions of the Ordovician?


Input: Consider Input: Passage: The earliest occurrences of the term in non-Christian literature include Josephus, referring to "the tribe of Christians, so named from him;" Pliny the Younger in correspondence with Trajan; and Tacitus, writing near the end of the 1st century. In the Annals he relates that "by vulgar appellation [they were] commonly called Christians" and identifies Christians as Nero's scapegoats for the Great Fire of Rome.


Output: Which group is identified as Tacitus scapegoat for the Great Fire of Rome?
