TASK DEFINITION: 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.
PROBLEM: Passage: In November 2014, Sony Pictures Entertainment was targeted by hackers who released details of confidential e-mails between Sony executives regarding several high-profile film projects. Included within these were several memos relating to the production of Spectre, claiming that the film was over budget, detailing early drafts of the script written by John Logan, and expressing Sony's frustration with the project. Eon Productions later issued a statement confirming the leak of what they called "an early version of the screenplay".

SOLUTION: Which company was targeted by hackers in November 2004?

PROBLEM: Passage: Numerous plays are put on every year at Eton College; there is one main theatre, called the Farrer (seating 400) and 2 Studio theatres, called the Caccia Studio and Empty Space (seating 90 and 80 respectively). There are about 8 or 9 house productions each year, around 3 or 4 "independent" plays (not confined solely to one house, produced, directed and funded by Etonians) and three school plays, one specifically for boys in the first two years, and two open to all years. The School Plays have such good reputations that they are normally fully booked every night. Productions also take place in varying locations around the School, varying from the sports fields to more historic buildings such as Upper School and College Chapel.

SOLUTION: How many people can sit in College Chapel?

PROBLEM: Passage: The first blue-violet LED using magnesium-doped gallium nitride was made at Stanford University in 1972 by Herb Maruska and Wally Rhines, doctoral students in materials science and engineering. At the time Maruska was on leave from RCA Laboratories, where he collaborated with Jacques Pankove on related work. In 1971, the year after Maruska left for Stanford, his RCA colleagues Pankove and Ed Miller demonstrated the first blue electroluminescence from zinc-doped gallium nitride, though the subsequent device Pankove and Miller built, the first actual gallium nitride light-emitting diode, emitted green light. In 1974 the U.S. Patent Office awarded Maruska, Rhines and Stanford professor David Stevenson a patent for their work in 1972 (U.S. Patent US3819974 A) and today magnesium-doping of gallium nitride continues to be the basis for all commercial blue LEDs and laser diodes. These devices built in the early 1970s had too little light output to be of practical use and research into gallium nitride devices slowed. In August 1989, Cree introduced the first commercially available blue LED based on the indirect bandgap semiconductor, silicon carbide (SiC). SiC LEDs had very low efficiency, no more than about 0.03%, but did emit in the blue portion of the visible light spectrum.[citation needed]

SOLUTION:
The first red-violet LED was developed at what University?
