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: 1,500 V DC is used in the Netherlands, Japan, Republic Of Indonesia, Hong Kong (parts), Republic of Ireland, Australia (parts), India (around the Mumbai area alone, has been converted to 25 kV AC like the rest of India), France (also using 25 kV 50 Hz AC), New Zealand (Wellington) and the United States (Chicago area on the Metra Electric district and the South Shore Line interurban line). In Slovakia, there are two narrow-gauge lines in the High Tatras (one a cog railway). In Portugal, it is used in the Cascais Line and in Denmark on the suburban S-train system.
[EX A]: In Romania, there are two narrow-gauge lines where?

[EX Q]: Passage: Hyperbaric (high-pressure) medicine uses special oxygen chambers to increase the partial pressure of O
2 around the patient and, when needed, the medical staff. Carbon monoxide poisoning, gas gangrene, and decompression sickness (the 'bends') are sometimes treated using these devices. Increased O
2 concentration in the lungs helps to displace carbon monoxide from the heme group of hemoglobin. Oxygen gas is poisonous to the anaerobic bacteria that cause gas gangrene, so increasing its partial pressure helps kill them. Decompression sickness occurs in divers who decompress too quickly after a dive, resulting in bubbles of inert gas, mostly nitrogen and helium, forming in their blood. Increasing the pressure of O
2 as soon as possible is part of the treatment.
[EX A]: What medicines to do hyperbaric chambers use?

[EX Q]: Passage: “The roots of all our modern academic fields can be found within the pages of literature.”  Literature in all its forms can be seen as written records, whether the literature itself be factual or fictional, it is still quite possible to decipher facts through things like characters’ actions and words or the authors’ style of writing and the intent behind the words. The plot is for more than just entertainment purposes; within it lies information about economics, psychology, science, religions, politics, cultures, and social depth. Studying and analyzing literature becomes very important in terms of learning about our history. Through the study of past literature we are able to learn about how society has evolved and about the societal norms during each of the different periods all throughout history. This can even help us to understand references made in more modern literature because authors often make references to Greek mythology and other old religious texts or historical moments. Not only is there literature written on each of the aforementioned topics themselves, and how they have evolved throughout history (like a book about the history of economics or a book about evolution and science, for example) but we can also learn about these things in fictional works. Authors often include historical moments in their works, like when Lord Byron talks about the Spanish and the French in ‘‘Childe Harold’s Pilgrimage: Canto I’’ and expresses his opinions through his character Childe Harold. Through literature we are able to continuously uncover new information about history. It is easy to see how all academic fields have roots in literature. Information became easier to pass down from generation to generation once we began to write it down. Eventually everything was written down, from things like home remedies and cures for illness, or how to build shelter to traditions and religious practices. From there people were able to study literature, improve on ideas, further our knowledge, and academic fields such as the medical field or trades could be started. In much the same way as the literature that we study today continue to be updated as we continue to evolve and learn more and more.
[EX A]:
Literature in most forms can be seen as what?
