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: Cork is home to one of Ireland's main national newspapers, the Irish Examiner (formerly the Cork Examiner). It also prints the Evening Echo, which for decades has been connected to the Echo Boys, who were poor and often homeless children who sold the newspaper. Today, the shouts of the vendors selling the Echo can still be heard in various parts of the city centre. One of the biggest free newspapers in the city is the Cork Independent. The city's University publishes the UCC Express and Motley magazine.
What did the Irish Examiner change its name to?

Passage: Melatonin is absent from the system or undetectably low during daytime. Its onset in dim light, dim-light melatonin onset (DLMO), at roughly 21:00 (9 p.m.) can be measured in the blood or the saliva. Its major metabolite can also be measured in morning urine. Both DLMO and the midpoint (in time) of the presence of the hormone in the blood or saliva have been used as circadian markers. However, newer research indicates that the melatonin offset may be the more reliable marker. Benloucif et al. found that melatonin phase markers were more stable and more highly correlated with the timing of sleep than the core temperature minimum. They found that both sleep offset and melatonin offset are more strongly correlated with phase markers than the onset of sleep. In addition, the declining phase of the melatonin levels is more reliable and stable than the termination of melatonin synthesis.
When is Meletonin found in the system?

Passage: In the autumn of 1991, talks were held for the broadcast rights for Premier League for a five-year period, from the 1992 season. ITV were the current rights holders, and fought hard to retain the new rights. ITV had increased its offer from £18m to £34m per year to keep control of the rights. BSkyB joined forces with the BBC to make a counter bid. The BBC was given the highlights of most of the matches, while BSkyB paying £304m for the Premier League rights, would give them a monopoly of all live matches, up to 60 per year from the 1992 season.  Murdoch described sport as a "battering ram" for pay-television, providing a strong customer base. A few weeks after the deal, ITV went to the High Court to get an injunction as it believed their bid details had been leaked before the decision was taken. ITV also asked the Office of Fair Trading to investigate since it believed Rupert Murdoch's media empire via its newspapers had influenced the deal. A few days later neither action took effect, ITV believed BSkyB was telephoned and informed of its £262m bid, and Premier League advised BSkyB to increase its counter bid.

What company was not concerned about retaining new rights?
