Passage: The panel has at various times been attributed to van der Goes and van Eyck, but was recognized as by Memling as early as the time of the seminal 1902 exhibition Exposition des primitifs flamands a Bruges in Bruges, when it was lent by Leopold Goldschmidt of Paris. In 1916 Max J. Friedlander described it as "without doubt" by Memling, and c. 1475. The art historian Catheline Perier-d'Ieteren, while noting that Memling's portrait faces were rarely underdrawn, wrote that this panel contains "thin yet confident incised lines" which may be preliminary drawings for Maria's face, perhaps made from life.
The triptych was recorded in an inventory of Tommaso's holdings upon his death. The New York panels passed through Tommaso's son Francesco. The central panel was described in his 1544 will as "a small tabernacle with three movable wings, in which is depicted the glorious Virgin Mary and the father and mother of the donor" (unum tabernaculettum que clauditur con tribus sportellis, in qua est depicta imago Gloriossime virginis Marie et patris et matris dicti testatoris). Francesco bequeathed the triptych to the convent of the hospital of Santa Maria Nuova in Florence. Records indicate a small intact winged altarpiece which stayed in the hospital's possession until around the time of the Napoleonic occupation, when it was probably broken up.Maria's panel was sold as a Dieric Bouts for 6,000 francs in 1870. It later passed through several private collections before arriving in the possession of Elia Volpi of Rome, who briefly returned it to Florence. Thereafter the panels were in London from 1901, from where they were sold to Villeroy Goldschmidt of Paris by for $426,500 in 1910. They were purchased, also in 1910, by the collector Benjamin Altman of New York on the advice of Max Friedlander, along with works by Albrecht Durer, Gerard David and Hans Holbein the Younger paintings whose "grave austerity seems to have been most in tune with his own taste". Altman bequeathed his holdings to the Metropolitan on his death in 1913.
Question: What was probably broken up around the time of the Napoleonic occupation?
answer:
winged altarpiece.

Passage: Although weakened and pushed south beyond the Huai River, the Southern Song found new ways to bolster its strong economy and defend itself against the Jin dynasty. It had able military officers such as Yue Fei and Han Shizhong. The government sponsored massive shipbuilding and harbor improvement projects, and the construction of beacons and seaport warehouses to support maritime trade abroad, including at the major international seaports, such as Quanzhou, Guangzhou, and Xiamen, that were sustaining China's commerce.To protect and support the multitude of ships sailing for maritime interests into the waters of the East China Sea and Yellow Sea (to Korea and Japan), Southeast Asia, the Indian Ocean, and the Red Sea, it was necessary to establish an official standing navy. The Song dynasty therefore established China's first permanent navy in 1132, with a headquarters at Dinghai. With a permanent navy, the Song were prepared to face the naval forces of the Jin on the Yangtze River in 1161, in the Battle of Tangdao and the Battle of Caishi. During these battles the Song navy employed swift paddle wheel driven naval vessels armed with traction trebuchet catapults aboard the decks that launched gunpowder bombs. Although the Jin forces commanded by Wanyan Liang (the Prince of Hailing) boasted 70,000 men on 600 warships, and the Song forces only 3,000 men on 120 warships, the Song dynasty forces were victorious in both battles due to the destructive power of the bombs and the rapid assaults by paddle wheel ships. The strength of the navy was heavily emphasized after that. A century after the navy was founded it had grown in size to 52,000 fighting marines.
The Song government confiscated portions of land owned by the landed gentry in order to raise revenue for these projects, an act which caused dissension and loss of loyalty amongst leading members of Song society but did not stop the Song's defensive preparations. Financial matters were made worse by the fact that many wealthy, land-owning familiessome of which had officials working for the governmentused their social connections with those in office in order to obtain tax-exempt status.Although the Song dynasty was able to hold back the Jin, a new foe came to power over the steppe, deserts, and plains north of the Jin dynasty. The Mongols, led by Genghis Khan (r. 12061227), initially invaded the Jin dynasty in 1205 and 1209, engaging in large raids across its borders, and in 1211 an enormous Mongol army was assembled to invade the Jin. The Jin dynasty was forced to submit and pay tribute to the Mongols as vassals; when the Jin suddenly moved their capital city from Beijing to Kaifeng, the Mongols saw this as a revolt. Under the leadership of Ogedei Khan (r.12291241), both the Jin dynasty and Western Xia dynasty were conquered by Mongol forces. The Mongols also invaded Korea, the Abbasid Caliphate of the Middle East and the Kievan Rus'.
Question: What is the full name of the dynasty whose government sponsored major international seaports that were sustaining China's commerce?
answer:
Southern Song.

Passage: Whales are a widely distributed and diverse group of fully aquatic placental marine mammals. They are an informal grouping within the infraorder Cetacea, usually excluding dolphins and porpoises. Whales, dolphins and porpoises belong to the order Cetartiodactyla, which consists of even-toed ungulates. Their closest living relatives are the hippopotamuses, having diverged about 40 million years ago. The two parvorders of whales, baleen whales (Mysticeti) and toothed whales (Odontoceti), are thought to have split apart around 34 million years ago. Whales consist of eight extant families: Balaenopteridae (the rorquals), Balaenidae (right whales), Cetotheriidae (the pygmy right whale), Eschrichtiidae (the grey whale), Monodontidae (belugas and narwhals), Physeteridae (the sperm whale), Kogiidae (the dwarf and pygmy sperm whale), and Ziphiidae (the beaked whales).
Whales are creatures of the open ocean; they feed, mate, give birth, suckle and raise their young at sea. So extreme is their adaptation to life underwater that they are unable to survive on land. Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 29.9 metres (98 ft) and 190 metric tons (210 short tons) blue whale, which is the largest creature that has ever lived. The sperm whale is the largest toothed predator on earth. Several species exhibit sexual dimorphism, in that the females are larger than males. Baleen whales have no teeth; instead they have plates of baleen, a fringe-like structure used to expel water while retaining the krill and plankton which they feed on. They use their throat pleats to expand the mouth to take in huge gulps of water. Balaenids have heads that can make up 40% of their body mass to take in water. Toothed whales, on the other hand, have conical teeth adapted to catching fish or squid. Baleen whales have a well developed sense of "smell", whereas toothed whales have well-developed hearing their hearing, that is adapted for both air and water, is so well developed that some can survive even if they are blind. Some species, such as sperm whales, are well adapted for diving to great depths to catch squid and other favoured prey.
Question: What are the type of whales that can survive even if blind?
answer:
Toothed.
