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.

Example Input: Passage: Cork is home to the RTÉ Vanbrugh Quartet, and to many musical acts, including John Spillane, The Frank And Walters, Sultans of Ping, Simple Kid, Microdisney, Fred, Mick Flannery and the late Rory Gallagher. Singer songwriter Cathal Coughlan and Sean O'Hagan of The High Llamas also hail from Cork. The opera singers Cara O'Sullivan, Mary Hegarty, Brendan Collins, and Sam McElroy are also Cork born. Ranging in capacity from 50 to 1,000, the main music venues in the city are the Cork Opera House (capacity c.1000), Cyprus Avenue, Triskel Christchurch, the Roundy, the Savoy and Coughlan's.[citation needed] Cork's underground scene is supported by Plugd Records.[citation needed]
Example Output: What Opera singers currently lives in Cork?

Example Input: Passage: The structure of a mosque is simple and it expresses openness. Calligraphic inscriptions from the Quran decorate mosques and mausoleums in Punjab. The inscriptions on bricks and tiles of the mausoleum of Shah Rukn-e-Alam (1320 AD) at Multan are outstanding specimens of architectural calligraphy. The earliest existing building in South Asia with enamelled tile-work is the tomb of Shah Yusuf Gardezi (1150 AD) at Multan. A specimen of the sixteenth century tile-work at Lahore is the tomb of Sheikh Musa Ahangar, with its brilliant blue dome. The tile-work of Emperor Shah Jahan is of a richer and more elaborate nature. The pictured wall of Lahore Fort is the last line in the tile-work in the entire world.
Example Output: Where does the structure of a mosque come from?

Example Input: Passage: Areas that should not be soldered may be covered with solder resist (solder mask). One of the most common solder resists used today is called "LPI" (liquid photoimageable solder mask).  A photo-sensitive coating is applied to the surface of the PWB, then exposed to light through the solder mask image film, and finally developed where the unexposed areas are washed away. Dry film solder mask is similar to the dry film used to image the PWB for plating or etching. After being laminated to the PWB surface it is imaged and develop as LPI. Once common but no longer commonly used because of its low accuracy and resolution is to screen print epoxy ink. Solder resist also provides protection from the environment.
Example Output:
Areas that should be soldered may be covered with what?
