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: Jehovah's Witnesses are organized hierarchically, in what the leadership calls a "theocratic organization", reflecting their belief that it is God's "visible organization" on earth. The organization is led by the Governing Body—an all-male group that varies in size, but since early 2014 has comprised seven members,[note 1] all of whom profess to be of the "anointed" class with a hope of heavenly life—based in the Watch Tower Society's Brooklyn headquarters. There is no election for membership; new members are selected by the existing body. Until late 2012, the Governing Body described itself as the representative and "spokesman" for God's "faithful and discreet slave class" (approximately 10,000 self-professed "anointed" Jehovah's Witnesses). At the 2012 Annual Meeting of the Watch Tower Society, the "faithful and discreet slave" was defined as referring to the Governing Body only. The Governing Body directs several committees that are responsible for administrative functions, including publishing, assembly programs and evangelizing activities. It appoints all branch committee members and traveling overseers, after they have been recommended by local branches, with traveling overseers supervising circuits of congregations within their jurisdictions. Traveling overseers appoint local elders and ministerial servants, and while branch offices may appoint regional committees for matters such as Kingdom Hall construction or disaster relief.
Example Output: How many Governing Body members were there in late 2012?

Example Input: Passage: Blues rock acts that pioneered the sound included Cream, The Jimi Hendrix Experience, and The Jeff Beck Group. Cream, in songs like "I Feel Free" (1966) combined blues rock with pop and psychedelia, particularly in the riffs and guitar solos of Eric Clapton. Jimi Hendrix produced a form of blues-influenced psychedelic rock, which combined elements of jazz, blues and rock and roll. From 1967 Jeff Beck brought lead guitar to new heights of technical virtuosity and moved blues rock in the direction of heavy rock with his band, The Jeff Beck Group. Dave Davies of The Kinks, Keith Richards of The Rolling Stones, Pete Townshend of The Who, Hendrix, Clapton and Beck all pioneered the use of new guitar effects like phasing, feedback and distortion. The Beatles began producing songs in the new hard rock style beginning with the White Album in 1968 and, with the track "Helter Skelter", attempted to create a greater level of noise than the Who. Stephen Thomas Erlewine of AllMusic has described the "proto-metal roar" of "Helter Skelter," while Ian MacDonald argued that "their attempts at emulating the heavy style were without exception embarrassing."
Example Output: Who was a hard rock act that pioneered the blues sound?

Example Input: Passage: The rapid expansion of the Rus' to the south led to conflict and volatile relationships with the Khazars and other neighbors on the Pontic steppe. The Khazars dominated the Black Sea steppe during the 8th century, trading and frequently allying with the Byzantine Empire against Persians and Arabs. In the late 8th century, the collapse of the Göktürk Khaganate led the Magyars and the Pechenegs, Ugric and Turkic peoples from Central Asia, to migrate west into the steppe region, leading to military conflict, disruption of trade, and instability within the Khazar Khaganate. The Rus' and Slavs had earlier allied with the Khazars against Arab raids on the Caucasus, but they increasingly worked against them to secure control of the trade routes.
Example Output:
What led to intermittent problems for the Khazars?
