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.

Ex Input:
Passage: Labour went on to win the 1950 general election, but with a much reduced majority of five seats. Soon afterwards, defence became a divisive issue within the party, especially defence spending (which reached a peak of 14% of GDP in 1951 during the Korean War), straining public finances and forcing savings elsewhere. The Chancellor of the Exchequer, Hugh Gaitskell, introduced charges for NHS dentures and spectacles, causing Bevan, along with Harold Wilson (then President of the Board of Trade), to resign over the dilution of the principle of free treatment on which the NHS had been established.

Ex Output:
In what year did Labour lose the general election?

Ex Input:
Passage: The exodus of Huguenots from France created a brain drain, as many Huguenots had occupied important places in society. The kingdom did not fully recover for years. The French crown's refusal to allow non-Catholics to settle in New France may help to explain that colony's slow rate of population growth compared to that of the neighbouring British colonies, which opened settlement to religious dissenters. By the time of the French and Indian War (the North American front of the Seven Years' War), a sizeable population of Huguenot descent lived in the British colonies, and many participated in the British defeat of New France in 1759-60.

Ex Output:
In what year did the French and Indian War begin?
