Passage: The spotted green pigeon or Liverpool pigeon (Caloenas maculata) is a species of pigeon which is most likely extinct. It was first mentioned and described in 1783 by John Latham, who had seen two specimens of unknown provenance and a drawing depicting the bird. The taxonomic relationships of the bird were long obscure, and early writers suggested many different possibilities, though the idea that it was related to the Nicobar pigeon (C. nicobarica) prevailed, and it was therefore placed in the same genus, Caloenas. Today, the species is only known from a specimen kept in World Museum, Liverpool. Overlooked for much of the 20th century, it was recognised as a valid extinct species by the IUCN Red List only in 2008. In 2014 a genetic study confirmed it as a distinct species related to the Nicobar pigeon, and showed that the two were the closest relatives of the extinct dodo and Rodrigues solitaire.
 Link Information: The animal order Columbiformes is also constituted of pigeons and doves, and includes about 42 genera and 310 species.
 Question: How many species of pigeons are there?

Answer: 310

Passage: Plucknett describes Bracton in this way: "Two generations after Ranulf de Glanvill we come to the flower and crown of English jurisprudence – Bracton." Bracton was born around 1210 in Devon and had a great deal of preferment in the Church. He either derived from Bratton Fleming or Bratton Clovelly. Both villages are in Devon. It was only after his death that the family name appears as Bracton; during his life, he was known as Bratton, or Bretton. This originally may have been Bradton, meaning "Broad Town". Bracton first appeared as a justice in 1245. From 1248 until his death in 1268 he was steadily employed as a justice of the assize in the southwestern counties, especially Somerset, Devon and Cornwall. He was a member of the coram rege, also called the coram ipso rege, later to become the King's Court. He retired from this in 1257, shortly before the meeting of the Mad Parliament in 1258 at Oxford. It is unknown whether his retirement was related to politics. His leaving coincided with the onset of the notorious Second Barons' War in 1264. At that time Bracton was ordered to restore to the Treasury the large store of plea rolls (case records from previous trials) that had been in his possession. He was also forced to surrender the large number of rolls from his predecessors Martin Pateshull and William Raleigh, also known as William de Raley. It cannot be determined whether he disgraced the King or the barons in this affair, but it is speculated that some kind of political intrigue was involved. The practical result was that his major work, De Legibus et Consuetudinibus Angliae ("The Laws and Customs of England"), was left unfinished. Even so, it exists in four large volumes today. He continued to follow the assizes in the southwest until 1267. In the last year of his life he filled another prominent role, as member of a commission of prelates, magnates and justices appointed to hear the complaints of the "disinherited" – those who had sided with Simon de Montfort, 6th Earl of Leicester.
 Link Information: Martin of Pattishall (died 14 November 1229) was an English judge.

He took his name from the village of Pattishall in Northamptonshire and was the clerk of Simon of Pattishall, although they were apparently unrelated. By 1201 he was already respected enough to be collecting the Plea rolls from the clerks of other judges on Eyre. After the end of the First Barons' War Pattishall became the leader of Henry III's professional legal servants, and was instrumental in reestablishing the courts. Between 1217 and 1218 he was a justice on Eyre in Yorkshire and Question: Which of Bracton's predecessors served in their position the longest?

Ex Output:
Answer: Raley

Passage: In November 1942, American and British forces landed in North Africa under Operation Torch. Allied thrusts overran Vichy French Morocco and Algeria and advanced into Tunisia. The danger for the Axis Powers was now apparent. The Allied forces advancing eastward and the British 8th Army advancing westward after the victory at the Second Battle of El Alamein, would trap and destroy the remaining Axis forces in North Africa. In response to the crisis, and the poor state of Axis forces, reinforcements for the German Afrika Korps, Italian Army and Luftwaffe were dispatched by sea and air. These reinforcements duly staved off an immediate defeat in Tunisia, the last region still in Axis hands. The poor state of the roads and rail lines in Algeria meant that Allied forces faced difficult logistic challenges which enabled the Axis to prolong a defence. The inexperience of U.S. forces was also apparent at the Battle of the Kasserine Pass. Nevertheless, the growing number and experience of Allied forces squeezed the Axis toward the northern tip of Tunisia. The Royal Air Force (RAF) and Royal Navy operating from Malta took a heavy toll of Axis shipping. However, Axis supplies were still reaching the besieged Afrika Korps by air. By early April, large quantities of Axis manpower was also being evacuated by air. Although the Allies held air superiority by this time, Luftwaffe transports were operating with impunity during darkness.
