Problem: Data compression:

In a further refinement of the direct use of probabilistic modelling, statistical estimates can be coupled to an algorithm called arithmetic coding. Arithmetic coding is a more modern coding technique that uses the mathematical calculations of a finite-state machine to produce a string of encoded bits from a series of input data symbols. It can achieve superior compression to other techniques such as the better-known Huffman algorithm. It uses an internal memory state to avoid the need to perform a one-to-one mapping of individual input symbols to distinct representations that use an integer number of bits, and it clears out the internal memory only after encoding the entire string of data symbols. Arithmetic coding applies especially well to adaptive data compression tasks where the statistics vary and are context-dependent, as it can be easily coupled with an adaptive model of the probability distribution of the input data. An early example of the use of arithmetic coding was its use as an optional (but not widely used) feature of the JPEG image coding standard. It has since been applied in various other designs including H.264/MPEG-4 AVC and HEVC for video coding.

Problem: Seven clubs have won the FA Cup as part of a League and Cup double, namely Preston North End (1889), Aston Villa (1897), Tottenham Hotspur (1961), Arsenal (1971, 1998, 2002), Liverpool (1986), Manchester United (1994, 1996, 1999) and Chelsea (2010). In 1993, Arsenal became the first side to win both the FA Cup and the League Cup in the same season when they beat Sheffield Wednesday 21 in both finals. Liverpool (in 2001) and Chelsea (in 2007) have since repeated this feat. In 2012, Chelsea accomplished a different cup double consisting of the FA Cup and the 2012 Champions League. In 199899, Manchester United added the 1999 Champions League title to their league and cup double to complete a unique Treble. Two years later, in 200001, Liverpool won the FA Cup, League Cup and UEFA Cup to complete a cup treble. An English Treble has never been achieved.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Amensalism is an interaction where an organism inflicts harm to another organism without any costs or benefits received by the other. A clear case of amensalism is where sheep or cattle trample grass. Whilst the presence of the grass causes negligible detrimental effects to the animal's hoof, the grass suffers from being crushed. Amensalism is often used to describe strongly asymmetrical competitive interactions, such as has been observed between the Spanish ibex and weevils of the genus Timarcha which feed upon the same type of shrub. Whilst the presence of the weevil has almost no influence on food availability, the presence of ibex has an enormous detrimental effect on weevil numbers, as they consume significant quantities of plant matter and incidentally ingest the weevils upon it.
What happens if a weevil eats from an ibex?
A: unanswerable

Context and question: During the Napoleonic Wars he was taken seriously by the British press as a dangerous tyrant, poised to invade. He was often referred to by the British as Boney. A nursery rhyme warned children that Bonaparte ravenously ate naughty people; the "bogeyman". The British Tory press sometimes depicted Napoleon as much smaller than average height, and this image persists. Confusion about his height also results from the difference between the French pouce and British inch2.71 cm and 2.54 cm, respectively. The myth of the "Napoleon Complex" named after him to describe men who have an inferiority complex stems primarily from the fact that he was listed, incorrectly, as 5 feet 2 inches (in French units) at the time of his death. In fact, he was 1.68 metres (5 ft 6 in) tall, an average height for a man in that period.[note 11]
Which foreign news service viewed Napoleon as a dangerous tyrant?
Answer: the British press

Question: Rugby union is the national sport in Samoa and the national team, nicknamed the Manu Samoa, is consistently competitive against teams from vastly more populous nations. Samoa has competed at every Rugby World Cup since 1991, and made the quarter finals in 1991, 1995 and the second round of the 1999 world cup. At the 2003 world cup, Manu Samoa came close to beating eventual world champions, England. Samoa also played in the Pacific Nations Cup and the Pacific Tri-Nations The sport is governed by the Samoa Rugby Football Union, who are members of the Pacific Islands Rugby Alliance, and thus, also contribute to the international Pacific Islanders rugby union team.

Question: In 2003, it was reported that one third of female academics "believe that discrimination or bullying by managers has held back their careers". It was said then that "A spokesman for Imperial said the college was acting on the recommendations and had already made changes". Nevertheless, allegations of bullying have continued: in 2007, concerns were raised about the methods that were being used to fire people in the Faculty of Medicine. New President of Imperial College, Alice Gast says she sees bright lights in the horizon for female careers at Imperial College London.
