Input: Literature
Poetry is a form of literary art which uses aesthetic and rhythmic qualities of language to evoke meanings in addition to, or in place of, prosaic ostensible meaning. Poetry has traditionally been distinguished from prose by its being set in verse;[a] prose is cast in sentences, poetry in lines; the syntax of prose is dictated by meaning, whereas that of poetry is held across metre or the visual aspects of the poem. Prior to the nineteenth century, poetry was commonly understood to be something set in metrical lines; accordingly, in 1658 a definition of poetry is "any kind of subject consisting of Rythm or Verses". Possibly as a result of Aristotle's influence (his Poetics), "poetry" before the nineteenth century was usually less a technical designation for verse than a normative category of fictive or rhetorical art. As a form it may pre-date literacy, with the earliest works being composed within and sustained by an oral tradition; hence it constitutes the earliest example of literature.

Input: Article: After the Romans left, Britain was invaded by Anglo-Saxon peoples. By AD 600 they had established control over much of what is now England, but Somerset was still in native British hands. The British held back Saxon advance into the south-west for some time longer, but by the early eighth century King Ine of Wessex had pushed the boundaries of the West Saxon kingdom far enough west to include Somerset. The Saxon royal palace in Cheddar was used several times in the 10th century to host the Witenagemot. After the Norman Conquest, the county was divided into 700 fiefs, and large areas were owned by the crown, with fortifications such as Dunster Castle used for control and defence. Somerset contains HM Prison Shepton Mallet, which was England's oldest prison still in use prior to its closure in 2013, having opened in 1610. In the English Civil War Somerset was largely Parliamentarian, with key engagements being the Sieges of Taunton and the Battle of Langport. In 1685 the Monmouth Rebellion was played out in Somerset and neighbouring Dorset. The rebels landed at Lyme Regis and travelled north, hoping to capture Bristol and Bath, but they were defeated in the Battle of Sedgemoor at Westonzoyland, the last pitched battle fought in England. Arthur Wellesley took his title, Duke of Wellington from the town of Wellington; he is commemorated on a nearby hill by a large, spotlit obelisk, known as the Wellington Monument.

Now answer this question: What prison does somerset county contain

Output: HM Prison Shepton Mallet, which was England's oldest prison still in use prior to its closure in 2013, having opened in 1610

Article: This set inherits a group operation (sometimes called coset multiplication, or coset addition) from the original group G: (gN) (hN) = (gh)N for all g and h in G. This definition is motivated by the idea (itself an instance of general structural considerations outlined above) that the map G G / N that associates to any element g its coset gN be a group homomorphism, or by general abstract considerations called universal properties. The coset eN = N serves as the identity in this group, and the inverse of gN in the quotient group is (gN)1 = (g1)N.e["]

Question: What is another term for coset multiplication?
Ans: coset addition

Here is a question about this article: Under the leadership of Vladimir Lenin, the Bolsheviks established the Soviet state on 7 November [O.S. 25 October] 1917, immediately after the Russian Provisional Government, which governed the Russian Republic, was overthrown during the October Revolution.

Meanwhile, anti-Bolsheviks coined the mocking label "Sovdepia" for the nascent state of the "Soviets of Workers' and Peasants' Deputies".
What is the answer to this question: Who led the group which created the Soviet state?
****
So... Vladimir Lenin

A number of meta-analyses have found clinical hypnosis to be effective in controlling pain associated with diagnostic and surgical procedures in both adults and children, as well as pain associated with cancer and childbirth. A 2007 review of 13 studies found evidence for the efficacy of hypnosis in the reduction of chronic pain in some conditions, though the number of patients enrolled in the studies was low, bringing up issues of power to detect group differences, and most lacked credible controls for placebo and/or expectation. The authors concluded that "although the findings provide support for the general applicability of hypnosis in the treatment of chronic pain, considerably more research will be needed to fully determine the effects of hypnosis for different chronic-pain conditions."
What is considerable more research needed to determine for different chronic pain conditions?
****
The answer: effects of hypnosis

In 1983, the International Telecommunication Union's radio telecommunications sector (ITU-R) set up a working party (IWP11/6) with the aim of setting a single international HDTV standard. One of the thornier issues concerned a suitable frame/field refresh rate, the world already having split into two camps, 25/50 Hz and 30/60 Hz, largely due to the differences in mains frequency. The IWP11/6 working party considered many views and throughout the 1980s served to encourage development in a number of video digital processing areas, not least conversion between the two main frame/field rates using motion vectors, which led to further developments in other areas. While a comprehensive HDTV standard was not in the end established, agreement on the aspect ratio was achieved.
How many frame/field rates were primarily being used in 1983?
****
The answer:
two
