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.

[Q]: Passage: Infrared reflectography (fr; it; es), as called by art conservators, can be applied to paintings to reveal underlying layers in a completely non-destructive manner, in particular the underdrawing or outline drawn by the artist as a guide. This often reveals the artist's use of carbon black, which shows up well in reflectograms, as long as it has not also been used in the ground underlying the whole painting. Art conservators are looking to see whether the visible layers of paint differ from the underdrawing or layers in between – such alterations are called pentimenti when made by the original artist. This is very useful information in deciding whether a painting is the prime version by the original artist or a copy, and whether it has been altered by over-enthusiastic restoration work. In general, the more pentimenti the more likely a painting is to be the prime version. It also gives useful insights into working practices.
[A]: What painting technique is used to reveal working practices?


[Q]: Passage: On March 31, 2010, the YouTube website launched a new design, with the aim of simplifying the interface and increasing the time users spend on the site. Google product manager Shiva Rajaraman commented: "We really felt like we needed to step back and remove the clutter." In May 2010, it was reported that YouTube was serving more than two billion videos a day, which it described as "nearly double the prime-time audience of all three major US television networks combined". In May 2011, YouTube reported in its company blog that the site was receiving more than three billion views per day. In January 2012, YouTube stated that the figure had increased to four billion videos streamed per day.

[Q]: Passage: In 1992, the university drafted a new Statement on Academic Freedom, specifying that limitations may be placed upon "expression with students or in public that: (1) contradicts or opposes, rather than analyzes or discusses, fundamental Church doctrine or policy; (2) deliberately attacks or derides the Church or its general leaders; or (3) violates the Honor Code because the expression is dishonest, illegal, unchaste, profane, or unduly disrespectful of others." These restrictions have caused some controversy as several professors have been disciplined according to the new rule. The American Association of University Professors has claimed that "infringements on academic freedom are distressingly common and that the climate for academic freedom is distressingly poor." The new rules have not affected BYU's accreditation, as the university's chosen accrediting body allows "religious colleges and universities to place limitations on academic freedom so long as they publish those limitations candidly", according to associate academic vice president Jim Gordon. The AAUP's concern was not with restrictions on the faculty member's religious expression but with a failure, as alleged by the faculty member and AAUP, that the restrictions had not been adequately specified in advance by BYU: "The AAUP requires that any doctrinal limitations on academic freedom be laid out clearly in writing. We [AAUP] concluded that BYU had failed to do so adequately."
