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.

Question: Passage: Oxygen was discovered independently by Carl Wilhelm Scheele, in Uppsala, in 1773 or earlier, and Joseph Priestley in Wiltshire, in 1774, but Priestley is often given priority because his work was published first. The name oxygen was coined in 1777 by Antoine Lavoisier, whose experiments with oxygen helped to discredit the then-popular phlogiston theory of combustion and corrosion. Its name derives from the Greek roots oxys, "acid", literally "sharp", referring to the sour taste of acids and - -genes, "producer", literally "begetter", because at the time of naming, it was mistakenly thought that all acids required oxygen in their composition. Common uses of oxygen includes the production cycle of steel, plastics and textiles, brazing, welding and cutting of steels and other metals, rocket propellant, in oxygen therapy and life support systems in aircraft, submarines, spaceflight and diving.

Answer: When did Carl Priestly discover oxygen?

Question: Passage: In the late 19th and early 20th century several forms of pragmatic philosophy arose. The ideas of pragmatism, in its various forms, developed mainly from discussions between Charles Sanders Peirce and William James when both men were at Harvard in the 1870s. James popularized the term "pragmatism", giving Peirce full credit for its patrimony, but Peirce later demurred from the tangents that the movement was taking, and redubbed what he regarded as the original idea with the name of "pragmaticism". Along with its pragmatic theory of truth, this perspective integrates the basic insights of empirical (experience-based) and rational (concept-based) thinking.

Answer: What year did Charles Sanders Peirce graduate from harvard?

Question: Passage: Some commentators have defined reverse discrimination as a policy or practice in which members of a majority are discriminated against in favor of a historically disadvantaged group or minority.[non-primary source needed] Many argue that reverse discrimination results from affirmative action policies and that these policies are just another form of discrimination no different from examples in the past. People like Ward Connerly assert that affirmative action requires the very discrimination it is seeking to eliminate. According to these opponents, this contradiction might make affirmative action counter-productive. One argument for reverse discrimination is the idea that affirmative action encourages mediocrity and incompetence. Job positions would not be offered to the applicants who are the most qualified, but to applicants with a special trait such as a certain race, ethnicity, or gender. For example, opponents say affirmative action causes unprepared applicants to be accepted in highly demanding educational institutions or jobs which result in eventual failure (see, for example, Richard Sander's study of affirmative action in Law School, bar exam and eventual performance at law firms). Other opponents say that affirmative action lowers the bar and so denies those who strive for excellence on their own merit and the sense of real achievement. Opponents of affirmative action suggest that merit should be the primary factor considered in applying for job positions, college, graduate school, etc.
