TASK DEFINITION: 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.
PROBLEM: Passage: Pomors are distinguished by the presence of Y Haplogroup N among them. Postulated to originate from southeast Asia, it is found at high rates in Uralic peoples. Its presence in Pomors (called "Northern Russians" in the report) attests to the non-Slavic tribes (mixing with Finnic tribes of northern Eurasia). Autosomally, Russians are generally similar to populations in central-eastern Europe but some northern Russians are intermediate to Finno-Ugric groups.

SOLUTION: What are Y Haplogroup N distinguished by?

PROBLEM: Passage: Alsace is one of the most conservative régions of France. It is one of just two régions in metropolitan France where the conservative right won the 2004 région elections and thus controls the Alsace Regional Council. Conservative leader Nicolas Sarkozy got his best score in Alsace (over 65%) in the second round of the French presidential elections of 2007. The president of the Regional Council is Philippe Richert, a member of the Union for a Popular Movement, elected in the 2010 regional election. The frequently changing status of the région throughout history has left its mark on modern day politics in terms of a particular interest in national identity issues. Alsace is also one of the most pro-EU regions of France. It was one of the few French regions that voted 'yes' to the European Constitution in 2005.

SOLUTION: What was Philippe Richert's score in Alsace?

PROBLEM: Passage: The role of the gas is to prevent evaporation of the filament, without introducing significant heat losses. For these properties, chemical inertness and high atomic or molecular weight is desirable. The presence of gas molecules knocks the liberated tungsten atoms back to the filament, reducing its evaporation and allowing it to be operated at higher temperature without reducing its life (or, for operating at the same temperature, prolongs the filament life). It however introduces heat losses (and therefore efficiency loss) from the filament, by heat conduction and heat convection.

SOLUTION:
Whose role is to allow evaporation of the filament?
