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.

[EX Q]: Passage: Popper contrasts his views with the notion of the "hopeful monster" that has large phenotype mutations and calls it the "hopeful behavioural monster". After behaviour has changed radically, small but quick changes of the phenotype follow to make the organism fitter to its changed goals. This way it looks as if the phenotype were changing guided by some invisible hand, while it is merely natural selection working in combination with the new behaviour. For example, according to this hypothesis, the eating habits of the giraffe must have changed before its elongated neck evolved. Popper contrasted this view as "evolution from within" or "active Darwinism" (the organism actively trying to discover new ways of life and being on a quest for conquering new ecological niches), with the naturalistic "evolution from without" (which has the picture of a hostile environment only trying to kill the mostly passive organism, or perhaps segregate some of its groups).
[EX A]: What happens after behavior changes only a little?

[EX Q]: Passage: Following al-Farabi's lead, Avicenna initiated a full-fledged inquiry into the question of being, in which he distinguished between essence (Mahiat) and existence (Wujud). He argued that the fact of existence can not be inferred from or accounted for by the essence of existing things, and that form and matter by themselves cannot interact and originate the movement of the universe or the progressive actualization of existing things. Existence must, therefore, be due to an agent-cause that necessitates, imparts, gives, or adds existence to an essence. To do so, the cause must be an existing thing and coexist with its effect.
[EX A]: Who followed Avicenna's leadand investigated the question of being?

[EX Q]: Passage: Victoria was physically unprepossessing—she was stout, dowdy and no more than five feet tall—but she succeeded in projecting a grand image. She experienced unpopularity during the first years of her widowhood, but was well liked during the 1880s and 1890s, when she embodied the empire as a benevolent matriarchal figure. Only after the release of her diary and letters did the extent of her political influence become known to the wider public. Biographies of Victoria written before much of the primary material became available, such as Lytton Strachey's Queen Victoria of 1921, are now considered out of date. The biographies written by Elizabeth Longford and Cecil Woodham-Smith, in 1964 and 1972 respectively, are still widely admired. They, and others, conclude that as a person Victoria was emotional, obstinate, honest, and straight-talking.
[EX A]:
How tall was Queen Victor?
