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 Q]: Passage: International friendlies give team managers the opportunity to experiment with team selection and tactics before the tournament proper, and also allow them to assess the abilities of players they may potentially select for the tournament squad. Players can be booked in international friendlies, and can be suspended from future international matches based on red cards or accumulated yellows in a specified period. Caps and goals scored also count towards a player's career records. In 2004, FIFA ruled that substitutions by a team be limited to six per match in international friendlies, in response to criticism that such matches were becoming increasingly farcical with managers making as many as 11 substitutions per match.
[EX A]: What do club Friendly's give team managers a chance to experiment with?

[EX Q]: Passage: For instance, a common use of a database system is to track information about users, their name, login information, various addresses and phone numbers. In the navigational approach all of this data would be placed in a single record, and unused items would simply not be placed in the database. In the relational approach, the data would be normalized into a user table, an address table and a phone number table (for instance). Records would be created in these optional tables only if the address or phone numbers were actually provided.
[EX A]: How is a database system rarely used?

[EX Q]: Passage: After the ceasefire following the Fall of France in June 1940, Alsace was annexed to Germany and a rigorous policy of Germanisation was imposed upon it by the Gauleiter Robert Heinrich Wagner. When, in July 1940, the first evacuees were allowed to return, only residents of Alsatian origin were admitted. The last Jews were deported on 15 July 1940 and the main synagogue, a huge Romanesque revival building that had been a major architectural landmark with its 54-metre-high dome since its completion in 1897, was set ablaze, then razed.
[EX A]:
In what year was Robert Heinrich Wagner made Gauleiter?
