Question: Passage: In Osbert: A Portrait of Osbert Lancaster, Boston comments that after the dramatic events in Athens his subject's later life was uneventful and industrious with "a somewhat dismaying dearth of rows, intrigues, scandals or scrapes to report." The Lancasters had a Georgian house in Henley-on-Thames, and a flat in Chelsea, where they lived from Mondays to Fridays. He worked at home in the mornings, on illustrations, stage designs, book reviews and any other commissions, before joining his wife for a midday dry martini and finally dressing and going to one of his clubs for lunch. After that he would walk to the Express building in  Fleet Street at about four in the afternoon. There he would gossip with his colleagues before sitting at his desk smoking furiously, producing the next day's pocket cartoon. By about half-past six he would have presented the cartoon to the editor and be ready for a drink at El Vino's across the road, and then the evening's social events.Karen Lancaster died in 1964. They were markedly different in character, she quiet and home-loving, he extrovert and gregarious, but they were devoted to each other, and her death left him devastated. Three years later he married the journalist Anne Scott-James; they had known each other for many years, although at first she did not much like him, finding him "stagey" and "supercilious". By the 1960s they had become good friends, and after Karen died the widowed Lancaster and the divorced Scott-James spent increasing amounts of time together. Their wedding was at the Chelsea Register Office on 2 January 1967. After their marriage they kept his Chelsea flat,  and lived at weekends in her house in the Berkshire village of Aldworth, the house in Henley having been sold. 
Question: What is the full name of the person who was extroverted and gregarious?

Answer: Osbert Lancaster.


Question: Passage: Conquistadors often wore steel armour that included chainmail and helmets. The Spanish were sufficiently impressed by the quilted cotton armour of their Maya enemies that they adopted it in preference to their own steel armour. Maya weaponry was not sufficiently powerful to justify the discomfort of wearing European armour. Quilted cotton armour, although still uncomfortably hot, was flexible and weighed much less. The Maya armour was adapted by the Spanish, who used knee-length quilted cotton tunics and Spanish-style caps. Horsemen wore long quilted cotton leg protectors; their horses were also protected with padded cotton armour. After the final push to the Petén lakes in early 1697, the Spanish recorded that they left with their garrison over 50 Dutch- and French-made muskets, three 1-pound (0.45 kg) calibre light cannons (piezas) cast from iron and mounted on carriages, four iron and two bronze pedreros (2-chambered stone-launchers) and six of at least eight bronze light cannons (known as esmiriles). 
Question: Who had four iron and two bronze pedreros?

Answer: the Spanish.


Question: Passage: Caspar David Friedrich (5 September 1774 – 7 May 1840) was a 19th-century German Romantic landscape painter, generally considered the most important German artist of his generation. He is best known for his mid-period allegorical landscapes which typically feature contemplative figures silhouetted against night skies, morning mists, barren trees or Gothic or megalithic ruins. His primary interest as an artist was the contemplation of nature, and his often symbolic and anti-classical work seeks to convey a subjective, emotional response to the natural world. Friedrich's paintings characteristically set a human presence in diminished perspective amid expansive landscapes, reducing the figures to a scale that, according to the art historian Christopher John Murray, directs "the viewer's gaze towards their metaphysical dimension".Friedrich was born in the town of Greifswald on the Baltic Sea in what was at the time Swedish Pomerania. He studied in Copenhagen until 1798, before settling in Dresden. He came of age during a period when, across Europe, a growing disillusionment with materialistic society was giving rise to a new appreciation of spirituality. This shift in ideals was often expressed through a reevaluation of the natural world, as artists such as Friedrich, J. M. W. Turner and John Constable sought to depict nature as a "divine creation, to be set against the artifice of human civilization".Friedrich's work brought him renown early in his career, and contemporaries such as the French sculptor David d'Angers spoke of him as a man who had discovered "the tragedy of landscape". Nevertheless, his work fell from favour during his later years, and he died in obscurity. As Germany moved towards modernisation in the late 19th century, a new sense of urgency characterised its art, and Friedrich's contemplative depictions of stillness came to be seen as the products of a bygone age. The early 20th century brought a renewed appreciation of his work, beginning in 1906 with an exhibition of thirty-two of his paintings in Berlin. By the 1920s his paintings had been discovered by the Expressionists, and in the 1930s and early 1940s Surrealists and Existentialists frequently drew ideas from his work. The rise of Nazism in the early 1930s again saw a resurgence in Friedrich's popularity, but this was followed by a sharp decline as his paintings were, by association with the Nazi movement, interpreted as having a nationalistic aspect. It was not until the late 1970s that Friedrich regained his reputation as an icon of the German Romantic movement and a painter of international importance. 
Question: What is the last name of the person who had a new appreciation for his work occur in the early 20th century?

Answer:
Friedrich.
