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: Despite yet another offer from the Institute for Advanced Study, Feynman rejected the Institute on the grounds that there were no teaching duties: Feynman felt that students were a source of inspiration and teaching was a diversion during uncreative spells. Because of this, the Institute for Advanced Study and Princeton University jointly offered him a package whereby he could teach at the university and also be at the institute.[citation needed] Feynman instead accepted an offer from the California Institute of Technology (Caltech)and as he says in his book Surely You're Joking Mr. Feynman!because a desire to live in a mild climate had firmly fixed itself in his mind while he was installing tire chains on his car in the middle of a snowstorm in Ithaca.
Why did Feynman decide to accept all offers from the Institute of Advanced Study?

Passage: International friendlies give team managers the opportunity to experiment with team selection and tactics before the tournament proper, and also allow them to assess the abilities of players they may potentially select for the tournament squad. Players can be booked in international friendlies, and can be suspended from future international matches based on red cards or accumulated yellows in a specified period. Caps and goals scored also count towards a player's career records. In 2004, FIFA ruled that substitutions by a team be limited to six per match in international friendlies, in response to criticism that such matches were becoming increasingly farcical with managers making as many as 11 substitutions per match.
What do club Friendly's give team managers a chance to experiment with?

Passage: Although most are non-aligned, some of the best known independent schools also belong to the large, long-established religious foundations, such as the Anglican Church, Uniting Church and Presbyterian Church, but in most cases, they do not insist on their students' religious allegiance. These schools are typically viewed as 'elite schools'. Many of the 'grammar schools' also fall in this category. They are usually expensive schools that tend to be up-market and traditional in style, some Catholic schools fall into this category as well, e.g. St Joseph's College, Gregory Terrace, Saint Ignatius' College, Riverview, St Gregory's College, Campbelltown, St Aloysius' College (Sydney) and St Joseph's College, Hunters Hill, as well as Loreto Kirribilli, Monte Sant Angelo Mercy College, St Ursula's College and Loreto Normanhurst for girls.
What denomination insists that students must also be a member of the founding church?
