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: Neptune has 14 known moons. Triton is the largest Neptunian moon, comprising more than 99.5% of the mass in orbit around Neptune,[e] and it is the only one massive enough to be spheroidal. Triton was discovered by William Lassell just 17 days after the discovery of Neptune itself. Unlike all other large planetary moons in the Solar System, Triton has a retrograde orbit, indicating that it was captured rather than forming in place; it was probably once a dwarf planet in the Kuiper belt. It is close enough to Neptune to be locked into a synchronous rotation, and it is slowly spiralling inward because of tidal acceleration. It will eventually be torn apart, in about 3.6 billion years, when it reaches the Roche limit. In 1989, Triton was the coldest object that had yet been measured in the Solar System, with estimated temperatures of 38 K (−235 °C).

Q: Passage: Terra preta (black earth), which is distributed over large areas in the Amazon forest, is now widely accepted as a product of indigenous soil management. The development of this fertile soil allowed agriculture and silviculture in the previously hostile environment; meaning that large portions of the Amazon rainforest are probably the result of centuries of human management, rather than naturally occurring as has previously been supposed. In the region of the Xingu tribe, remains of some of these large settlements in the middle of the Amazon forest were found in 2003 by Michael Heckenberger and colleagues of the University of Florida. Among those were evidence of roads, bridges and large plazas.

A: Terra preta is distributor over a small area of what?

Q: Passage: Until recently, in most critical writing the post-punk era was "often dismissed as an awkward period in which punk's gleeful ructions petered out into the vacuity of the Eighties". Contemporary scholars have argued to the contrary, asserting that the period produced significant innovations and music on its own. Simon Reynolds described the period as "a fair match for the sixties in terms of the sheer amount of great music created, the spirit of adventure and idealism that infused it, and the way that the music seemed inextricably connected to the political and social turbulence of its era". Nicholas Lezard wrote that the music of the period "was avant-garde, open to any musical possibilities that suggested themselves, united only in the sense that it was very often cerebral, concocted by brainy young men and women interested as much in disturbing the audience, or making them think, as in making a pop song".

A:
What musical period had no innovations?
