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 Input:
Passage: Min Nan texts, all Hokkien, can be dated back to the 16th century. One example is the Doctrina Christiana en letra y lengua china, presumably written after 1587 by the Spanish Dominicans in the Philippines. Another is a Ming Dynasty script of a play called Romance of the Lychee Mirror (1566), supposedly the earliest Southern Min colloquial text. Xiamen University has also developed an alphabet based on Pinyin, which has been published in a dictionary called the Minnan Fangyan-Putonghua Cidian (閩南方言普通話詞典) and a language teaching book, which is used to teach the language to foreigners and Chinese non-speakers. It is known as Pumindian.

Ex Output:
Who has developed an alphabet based on Pumindian?


Ex Input:
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 Output:
What medicines to do hyperbaric chambers use?


Ex Input:
Passage: Washington University's North Campus and West Campus principally house administrative functions that are not student focused. North Campus lies in St. Louis City near the Delmar Loop. The University acquired the building and adjacent property in 2004, formerly home to the Angelica Uniform Factory. Several University administrative departments are located at the North Campus location, including offices for Quadrangle Housing, Accounting and Treasury Services, Parking and Transportation Services, Army ROTC, and Network Technology Services. The North Campus location also provides off-site storage space for the Performing Arts Department. Renovations are still ongoing; recent additions to the North Campus space include a small eatery operated by Bon Appétit Management Company, the University's on-campus food provider, completed during spring semester 2007, as well as the Family Learning Center, operated by Bright Horizons and opened in September 2010.

Ex Output:

On what campuses are the student focused administrative functions located?
