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.

Input: Consider Input: Passage: Santa Monica was long inhabited by the Tongva people. Santa Monica was called Kecheek in the Tongva language. The first non-indigenous group to set foot in the area was the party of explorer Gaspar de Portola, who camped near the present day intersection of Barrington and Ohio Avenues on August 3, 1769. There are two different versions of the naming of the city. One says that it was named in honor of the feast day of Saint Monica (mother of Saint Augustine), but her feast day is actually May 4. Another version says that it was named by Juan Crespi on account of a pair of springs, the Kuruvungna Springs (Serra Springs), that were reminiscent of the tears that Saint Monica shed over her son's early impiety.

Output: What language did Gaspar de Portola speak?

Input: Consider Input: 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.

Output: What painting technique is used to reveal working practices?

Input: Consider Input: Passage: BYU has designated energy conservation, products and materials, recycling, site planning and building design, student involvement, transportation, water conservation, and zero waste events as top priority categories in which to further its efforts to be an environmentally sustainable campus. The university has stated that "we have a responsibility to be wise stewards of the earth and its resources." BYU is working to increase the energy efficiency of its buildings by installing various speed drives on all pumps and fans, replacing incandescent lighting with fluorescent lighting, retrofitting campus buildings with low-E reflective glass, and upgraded roof insulation to prevent heat loss. The student groups BYU Recycles, Eco-Response, and BYU Earth educate students, faculty, staff, and administrators about how the campus can decrease its environmental impact. BYU Recycles spearheaded the recent campaign to begin recycling plastics, which the university did after a year of student campaigning.
Output: What does BUY state about being a sustainable campus?
