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.

[Q]: Passage: In free-range husbandry, the birds can roam freely outdoors for at least part of the day. Often, this is in large enclosures, but the birds have access to natural conditions and can exhibit their normal behaviours. A more intensive system is yarding, in which the birds have access to a fenced yard and poultry house at a higher stocking rate. Poultry can also be kept in a barn system, with no access to the open air, but with the ability to move around freely inside the building. The most intensive system for egg-laying chickens is battery cages, often set in multiple tiers. In these, several birds share a small cage which restricts their ability to move around and behave in a normal manner. The eggs are laid on the floor of the cage and roll into troughs outside for ease of collection. Battery cages for hens have been illegal in the EU since January 1, 2012.
[A]: What is the benefit to chickens of being in a caged location?


[Q]: Passage: In 1987, in Canada, Elizabeth publicly supported politically divisive constitutional amendments, prompting criticism from opponents of the proposed changes, including Pierre Trudeau. The same year, the elected Fijian government was deposed in a military coup. Elizabeth, as monarch of Fiji, supported the attempts of the Governor-General, Ratu Sir Penaia Ganilau, to assert executive power and negotiate a settlement. Coup leader Sitiveni Rabuka deposed Ganilau and declared Fiji a republic. By the start of 1991, republican feeling in Britain had risen because of press estimates of the Queen's private wealth—which were contradicted by the Palace—and reports of affairs and strained marriages among her extended family. The involvement of the younger royals in the charity game show It's a Royal Knockout was ridiculed and the Queen was the target of satire.
[A]: What government was Pierre Trudeau prime minister of in 1987?
