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: During World War II, Hitler's Generalplan Ost (general plan for the East) entailed killing, deporting, or enslaving the Slavic and Jewish population of occupied Eastern Europe to create Lebensraum (living space) for German settlers. The Nazi Hunger Plan and Generalplan Ost would have led to the starvation of 80 million people in the Soviet Union. These partially fulfilled plans resulted in the deaths of an estimated 19.3 million civilians and prisoners of war.

Output: How many prisoners of war were supposed to die from the Hunger Plan?


Input: Consider Input: Passage: DeveloperWorks is a website run by IBM for software developers and IT professionals.

Subjects range from open, industry-standard technologies like Java, Linux, SOA and web services, web development, Ajax, PHP, and XML to IBM's products (WebSphere, Rational, Lotus, Tivoli and Information Management). In 2007, developerWorks was inducted into the Jolt Hall of Fame.

Output: Where was Java inducted in 2007?


Input: Consider Input: Passage: During World War II, San Diego became a major hub of military and defense activity, due to the presence of so many military installations and defense manufacturers. The city's population grew rapidly during and after World War II, more than doubling between 1930 (147,995) and 1950 (333,865). During the final months of the war, the Japanese had a plan to target multiple U.S. cities for biological attack, starting with San Diego. The plan was called "Operation Cherry Blossoms at Night" and called for kamikaze planes filled with fleas infected with plague (Yersinia pestis) to crash into civilian population centers in the city, hoping to spread plague in the city and effectively kill tens of thousands of civilians. The plan was scheduled to launch on September 22, 1945, but was not carried out because Japan surrendered five weeks earlier.


Output: When did San Diego's population grow so rapidly that it nearly tripled?
