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: YouTube entered into a marketing and advertising partnership with NBC in June 2006. In November 2008, YouTube reached an agreement with MGM, Lions Gate Entertainment, and CBS, allowing the companies to post full-length films and television episodes on the site, accompanied by advertisements in a section for US viewers called "Shows". The move was intended to create competition with websites such as Hulu, which features material from NBC, Fox, and Disney. In November 2009, YouTube launched a version of "Shows" available to UK viewers, offering around 4,000 full-length shows from more than 60 partners. In January 2010, YouTube introduced an online film rentals service, which is available only to users in the US, Canada and the UK as of 2010. The service offers over 6,000 films.
Example Output: Who entered into a partnership during June 2008 with NBC?

Example Input: Passage: Uranium carbides and uranium nitrides are both relatively inert semimetallic compounds that are minimally soluble in acids, react with water, and can ignite in air to form U
3O
8. Carbides of uranium include uranium monocarbide (UC), uranium dicarbide (UC
2), and diuranium tricarbide (U
2C
3). Both UC and UC
2 are formed by adding carbon to molten uranium or by exposing the metal to carbon monoxide at high temperatures. Stable below 1800 C, U
2C
3 is prepared by subjecting a heated mixture of UC and UC
2 to mechanical stress. Uranium nitrides obtained by direct exposure of the metal to nitrogen include uranium mononitride (UN), uranium dinitride (UN
2), and diuranium trinitride (U
2N
3).
Example Output: Along with uranium monocarbide and uranium dicarbide, what is a unnotable carbide of uranium?

Example Input: Passage: Of approximately 100 million native speakers of German in the world, roughly 80 million consider themselves Germans.[citation needed] There are an additional 80 million people of German ancestry mainly in the United States, Brazil (mainly in the South Region of the country), Argentina, Canada, South Africa, the post-Soviet states (mainly in Russia and Kazakhstan), and France, each accounting for at least 1 million.[note 2] Thus, the total number of Germans lies somewhere between 100 and more than 150 million, depending on the criteria applied (native speakers, single-ancestry ethnic Germans, partial German ancestry, etc.).
Example Output:
Where do an additional 80 million German natives live?
