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.

Example Input: Passage: There is a sizeable Greek minority of about 105,000 (disputed, sources claim higher) people, in Albania. The Greek minority of Turkey, which numbered upwards of 200,000 people after the 1923 exchange, has now dwindled to a few thousand, after the 1955 Constantinople Pogrom and other state sponsored violence and discrimination. This effectively ended, though not entirely, the three-thousand-year-old presence of Hellenism in Asia Minor. There are smaller Greek minorities in the rest of the Balkan countries, the Levant and the Black Sea states, remnants of the Old Greek Diaspora (pre-19th century).
Example Output:  What other countries don't boast of a Greek populace?

Example Input: Passage: For temperature studies, subjects must remain awake but calm and semi-reclined in near darkness while their rectal temperatures are taken continuously. Though variation is great among normal chronotypes, the average human adult's temperature reaches its minimum at about 05:00 (5 a.m.), about two hours before habitual wake time. Baehr et al. found that, in young adults, the daily body temperature minimum occurred at about 04:00 (4 a.m.) for morning types but at about 06:00 (6 a.m.) for evening types. This minimum occurred at approximately the middle of the eight hour sleep period for morning types, but closer to waking in evening types.
Example Output: What physical factor must be periodicly monitored in temperature studies?

Example Input: Passage: With the forced abdication of Emperor William II in 1918, Germany became a republic. Most of West Prussia and the former Prussian Province of Posen, territories annexed by Prussia in the 18th century Partitions of Poland, were ceded to the Second Polish Republic according to the Treaty of Versailles. East Prussia became an exclave, being separated from mainland Germany. After the Treaty of Versailles, East Prussia was separated from Germany as an exclave; the Memelland was also separated from the province. Because most of West Prussia became part of the Second Polish Republic as the Polish Corridor, the formerly West Prussian Marienwerder region became part of East Prussia (as Regierungsbezirk Westpreußen). Also Soldau district in Allenstein region was part of Second Polish Republic. The Seedienst Ostpreußen was established to provide an independent transport service to East Prussia.
Example Output:
In what year was William II crowned as Emperor?
