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: Han Chinese make up the vast majority of the population, and the largest Han subgroup are the speakers of Wu varieties of Chinese. There are also 400,000 members of ethnic minorities, including approximately 200,000 She people and approximately 20,000 Hui Chinese[citation needed]. Jingning She Autonomous County in Lishui is the only She autonomous county in China.
[A]: What kind of Japanese make up the vast majority of the population?


[Q]: Passage: In Homer's Iliad, the names Danaans (or Danaoi: Δαναοί) and Argives (Argives: Αργείοι) are used to designate the Greek forces opposed to the Trojans. The myth of Danaus, whose origin is Egypt, is a foundation legend of Argos. His daughters Danaides, were forced in Tartarus to carry a jug to fill a bathtub without a bottom. This myth is connected with a task that can never be fulfilled (Sisyphos) and the name can be derived from the PIE root *danu: "river". There is not any satisfactory theory on their origin. Some scholars connect Danaans with the Denyen, one of the groups of the sea peoples who attacked Egypt during the reign of Ramesses III (1187-1156 BCE). The same inscription mentions the Weshesh who might have been the Achaeans. The Denyen seem to have been inhabitants of the city Adana in Cilicia. Pottery similar to that of Mycenae itself has been found in Tarsus of Cilicia and it seems that some refugees from the Aegean went there after the collapse of the Mycenean civilization. These Cilicians seem to have been called Dananiyim, the same word as Danaoi who attacked Egypt in 1191 BC along with the Quaouash (or Weshesh) who may be Achaeans. They were also called Danuna according to a Hittite inscription and the same name is mentioned in the Amarna letters. Julius Pokorny reconstructs the name from the PIE root da:-: "flow, river", da:-nu: "any moving liquid, drops", da: navo "people living by the river, Skyth. nomadic people (in Rigveda water-demons, fem.Da:nu primordial goddess), in Greek Danaoi, Egypt. Danuna". It is also possible that the name Danaans is pre-Greek. A country Danaja with a city Mukana (propaply: Mycenea) is mentioned in inscriptions from Egypt from Amenophis III (1390-1352 BC), Thutmosis III (1437 BC).
[A]: In Homer's poems who were the Greeks not at odds with?


[Q]: Passage: There are three main chemical pulping processes: the sulfite process dates back to the 1840s and it was the dominant method extent before the second world war. The kraft process, invented in the 1870s and first used in the 1890s, is now the most commonly practiced strategy, one of its advantages is the chemical reaction with lignin, that produces heat, which can be used to run a generator. Most pulping operations using the kraft process are net contributors to the electricity grid or use the electricity to run an adjacent paper mill. Another advantage is that this process recovers and reuses all inorganic chemical reagents. Soda pulping is another specialty process used to pulp straws, bagasse and hardwoods with high silicate content.
[A]:
How many mechanical pulping processes exist?
