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: After the Peace of Westphalia, several border territories were assigned to the United Provinces. They were federally-governed Generality Lands (Generaliteitslanden). They were Staats-Brabant (present North Brabant), Staats-Vlaanderen (present Zeeuws-Vlaanderen), Staats-Limburg (around Maastricht) and Staats-Oppergelre (around Venlo, after 1715).
[EX A]: In 1715 what was assigned to the United Provinces?

[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: Protestants in general reject the veneration and invocation of the Saints.:1174 Protestants typically hold that Mary was the mother of Jesus, but was an ordinary woman devoted to God. Therefore, there is virtually no Marian veneration, Marian feasts, Marian pilgrimages, Marian art, Marian music or Marian spirituality in today's Protestant communities. Within these views, Roman Catholic beliefs and practices are at times rejected, e.g., theologian Karl Barth wrote that "the heresy of the Catholic Church is its Mariology".
[EX A]:
How many pieces of Marian music did theologian Karl Barth write?
