Problem: Botany:

During the 18th century, systems of plant identification were developed comparable to dichotomous keys, where unidentified plants are placed into taxonomic groups (e.g. family, genus and species) by making a series of choices between pairs of characters. The choice and sequence of the characters may be artificial in keys designed purely for identification (diagnostic keys) or more closely related to the natural or phyletic order of the taxa in synoptic keys. By the 18th century, new plants for study were arriving in Europe in increasing numbers from newly discovered countries and the European colonies worldwide. In 1753 Carl von Linné (Carl Linnaeus) published his Species Plantarum, a hierarchical classification of plant species that remains the reference point for modern botanical nomenclature. This established a standardised binomial or two-part naming scheme where the first name represented the genus and the second identified the species within the genus. For the purposes of identification, Linnaeus's Systema Sexuale classified plants into 24 groups according to the number of their male sexual organs. The 24th group, Cryptogamia, included all plants with concealed reproductive parts, mosses, liverworts, ferns, algae and fungi.

Problem: Norfolk Island was originally a colony acquired by settlement but was never within the British Settlements Act. It was accepted as a territory of Australia, separate from any state, by the Norfolk Island Act 1913 (Cth), passed under the territories power (Constitution section 122) and made effective in 1914. In 1976 the High Court of Australia held unanimously that Norfolk Island is a part of the Commonwealth. Again, in 2007 the High Court of Australia affirmed the validity of legislation that made Australian citizenship a necessary qualification for voting for, and standing for election to, the Legislative Assembly of Norfolk Island.
What was an unnecessary qualification for voting in Norfolk Island?

Context and question: In January 2010, YouTube launched an experimental version of the site that used the built-in multimedia capabilities of web browsers supporting the HTML5 standard. This allowed videos to be viewed without requiring Adobe Flash Player or any other plug-in to be installed. The YouTube site had a page that allowed supported browsers to opt into the HTML5 trial. Only browsers that supported HTML5 Video using the H.264 or WebM formats could play the videos, and not all videos on the site were available.

Question: In response to concerns that clubs were increasingly passing over young English players in favour of foreign players, in 1999, the Home Office tightened its rules for granting work permits to players from countries outside of the European Union. A non-EU player applying for the permit must have played for his country in at least 75 per cent of its competitive 'A' team matches for which he was available for selection during the previous two years, and his country must have averaged at least 70th place in the official FIFA world rankings over the previous two years. If a player does not meet those criteria, the club wishing to sign him may appeal.
Is there an answer to this question: Which entity tightened its rules in response to concerns about the clubs passing over British players?

Answer: unanswerable
