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: Four major AM radio stations based in or near Ann Arbor are WAAM 1600, a conservative news and talk station; WLBY 1290, a business news and talk station; WDEO 990, Catholic radio; and WTKA 1050, which is primarily a sports station. The city's FM stations include NPR affiliate WUOM 91.7; country station WWWW 102.9; and adult-alternative station WQKL 107.1. Freeform station WCBN-FM 88.3 is a local community radio/college radio station operated by the students of the University of Michigan featuring noncommercial, eclectic music and public-affairs programming. The city is also served by public and commercial radio broadcasters in Ypsilanti, the Lansing/Jackson area, Detroit, Windsor, and Toledo.

Passage: In February 2012, Capello resigned from his role as England manager, following a disagreement with the FA over their request to remove John Terry from team captaincy after accusations of racial abuse concerning the player. Following this, there was media speculation that Harry Redknapp would take the job. However, on 1 May 2012, Roy Hodgson was announced as the new manager, just six weeks before UEFA Euro 2012. England managed to finish top of their group, winning two and drawing one of their fixtures, but exited the Championships in the quarter-finals via a penalty shoot-out, this time to Italy.
In what year was Capello made England's manager?

Passage: In particular, this norm gets smaller when a number is multiplied by p, in sharp contrast to the usual absolute value (also referred to as the infinite prime). While completing Q (roughly, filling the gaps) with respect to the absolute value yields the field of real numbers, completing with respect to the p-adic norm |−|p yields the field of p-adic numbers. These are essentially all possible ways to complete Q, by Ostrowski's theorem. Certain arithmetic questions related to Q or more general global fields may be transferred back and forth to the completed (or local) fields. This local-global principle again underlines the importance of primes to number theory.

What happens to the norm when a number is multiplied by Q?
