question:
Question: Who is in charge of the city Couceiro arrived in in 1889? Passage:Paiva Couceiro arrived in Luanda, Angola on September 1, 1889, and was immediately appointed commander of the Irregular Cavalry Squadron in the village of Humpata (which was originally created by Artur de Paiva to combat bands of guerrillas along the plain of Moçâmedes). He did not remain at this outpost for long; apparently he was unsatisfied with his subordinates, their methods and inferior level of discipline, but was able to utilize them in a campaign to retrieve missing cattle, instead of hiring local Boer mercenaries, which had been the custom. By January he was in the village of Belmonte, in Bié, on a mission that would take him along the Cuando River, to Cuito and then to the Lialui along the Zambezi River (a trek of thousands of kilometers across savannah), in order to negotiate with Lewanika, chief of the Barotze tribe. The growth of the Portuguese occupation force in the Angolan interior was part of the administration's attempted to implement their Pink Map to explore and expand their serfdom over the peoples of the central-African interior. After some resistance, the colonial administration began a military campaign to pacify groups that had resisted initial token gestures of friendship and gifts, a process that Paiva Couceiro participated in energetically. For the chief's recognition of Portuguese sovereignty over his territories, Paiva Couceiro brought with him a colonels tunic and sword, textiles, gold, velvet, boxes of Porto wine and arms, which were to be delivered in 300 crates when the Governor of Angola canceled the project.

question:
Question: Was the man who consecrated Richardson in 1879 older than 50 at the time? Passage:Alfred Spencer Richardson was consecrated on 22 June 1879 in the Reformed Episcopal Church in Philadelphia, USA by William Rufus Nicholson, a bishop of the Reformed Episcopal Church, USA. WR Nicholson was consecrated for the Protestant Episcopal Church, USA on 24 February 1876 by Charles Edward Cheney who was consecrated (14 December 1873) by George David Cummins, American Episcopal assistant bishop of Kentucky, USA, and who was consecrated (15 November 1866) by John Henry Hopkins, Episcopal bishop of Vermont, USA. The line of succession to Hopkins is traceable from William Sancroft (enthroned archbishop of Canterbury, 1678) via Thomas White (bishop of Peterborough, England), George Hickes (assistant bishop of Thetford, England), James Gadderar (bishop of Aberdeen, Scotland), Thomas Rattray (bishop of Dunkeld, Scotland), William Falconer (or Falconar) (bishop of Caithness, Scotland), Robert Kilgour (bishop of Aberdeen, Scotland), Samuel Seabury (bishop of Connecticut, USA), Thomas Clagett (bishop of Maryland, USA), Edward Bass (bishop of Massachusetts, USA), Abraham Jarvis (bishop of Connecticut, USA), Alexander Viets Griswold (bishop of Eastern Diocese, USA) who in 1832 consecrated Hoskins.

question:
Question: Did Joseph Banks and Daniel Solander sail on the same ship as James Cook? Passage:Specimens of Lambertia formosa were collected by botanists Joseph Banks and Daniel Solander during Lieutenant James Cook's landing at Botany Bay between April and May in 1770. These are thought to have been obtained from vegetation currently known as the Eastern Suburbs Banksia Scrub that occurs in sandy areas near present-day La Perouse. The shrub was first described in 1798 by English botanist James Edward Smith who concurrently erected the new genus Lambertia, the name honouring English botanist Aylmer Bourke Lambert. The specific name formosa is the Latin adjective for 'handsome'. English plantsman Henry Charles Andrews wrote in 1799, "Of all the plants yet introduced from New Holland, that have hitherto flowered with us, this unquestionably takes the lead for beauty, considering the plant altogether", although his countryman Joseph Knight in his 1809 work On the cultivation of the plants belonging to the natural order of Proteeae added that the species name "applies only to the flowers, the foliage being generally of a sickly hue". French botanist Michel Gandoger described specimens collected at Hornsby and Port Jackson as Lambertia proxima, and material sent to him by plant collector Charles Walter as L. barbata in 1919; these turned out to be L. formosa. Gandoger described 212 taxa of Australian plants, almost all of which turned out to be species already described.
