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

question:
Passage: There are fifteen fraternities and seven sororities at the University of Chicago, as well as one co-ed community service fraternity, Alpha Phi Omega. Four of the sororities are members of the National Panhellenic Conference, and ten of the fraternities form the University of Chicago Interfraternity Council. In 2002, the Associate Director of Student Activities estimated that 8–10 percent of undergraduates were members of fraternities or sororities. The student activities office has used similar figures, stating that one in ten undergraduates participate in Greek life.
answer:
Along with 15 sororities, how many fraternities does the U of C have?

question:
Passage: Stephen Hawking in particular has addressed a connection between time and the Big Bang. In A Brief History of Time and elsewhere, Hawking says that even if time did not begin with the Big Bang and there were another time frame before the Big Bang, no information from events then would be accessible to us, and nothing that happened then would have any effect upon the present time-frame. Upon occasion, Hawking has stated that time actually began with the Big Bang, and that questions about what happened before the Big Bang are meaningless. This less-nuanced, but commonly repeated formulation has received criticisms from philosophers such as Aristotelian philosopher Mortimer J. Adler.
answer:

What does Mortimer J. Adler think time has a connection with?
