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.

Passage: To make pulp from wood, a chemical pulping process separates lignin from cellulose fibres. This is accomplished by dissolving lignin in a cooking liquor, so that it may be washed from the cellulose; this preserves the length of the cellulose fibres. Paper made from chemical pulps are also known as wood-free papers–not to be confused with tree-free paper; this is because they do not contain lignin, which deteriorates over time. The pulp can also be bleached to produce white paper, but this consumes 5% of the fibres; chemical pulping processes are not used to make paper made from cotton, which is already 90% cellulose.
What is separated from pulp to make wood?

Passage: The ultimate substantive legacy of Principia Mathematica is mixed. It is generally accepted that Kurt Gödel's incompleteness theorem of 1931 definitively demonstrated that for any set of axioms and inference rules proposed to encapsulate mathematics, there would in fact be some truths of mathematics which could not be deduced from them, and hence that Principia Mathematica could never achieve its aims. However, Gödel could not have come to this conclusion without Whitehead and Russell's book. In this way, Principia Mathematica's legacy might be described as its key role in disproving the possibility of achieving its own stated goals. But beyond this somewhat ironic legacy, the book popularized modern mathematical logic and drew important connections between logic, epistemology, and metaphysics.
What is the general consensus of the axioms and inference rules not declared in Principia Mathematica?

Passage: In the early 1980s, Downtown Manhattan's no wave scene transitioned from its abrasive origins into a more dance-oriented sound, with compilations such as ZE's Mutant Disco (1981) highlighting a newly playful sensibility borne out of the city's clash of hip hop, disco and punk styles, as well as dub reggae and world music influences. Artists such as Liquid Liquid, the B-52s, Cristina, Arthur Russell, James White and the Blacks and Lizzy Mercier Descloux pursued a formula described by Luc Sante as "anything at all + disco bottom". The decadent parties and art installations of venues such as Club 57 and the Mudd Club became cultural hubs for musicians and visual artists alike, with figures such as Jean-Michel Basquiat, Keith Haring and Michael Holman frequenting the scene. Other no wave-indebted groups such as Swans, Glenn Branca, the Lounge Lizards, Bush Tetras and Sonic Youth instead continued exploring the early scene's forays into noise and more abrasive territory.

When did the no wave scene decide not to transition?
