[EX Q]: Passage: The origins of the Early Netherlandish school lie in the miniature paintings of the late Gothic period.  This was first seen in manuscript illumination, which after 1380 conveyed new levels of realism, perspective and skill in rendering colour, peaking with the Limbourg brothers and the Netherlandish artist known as Hand G, to whom the most significant leaves of the Turin-Milan Hours are usually attributed. Although his identity has not been definitively established, Hand G, who contributed c. 1420, is thought to have been either Jan van Eyck or his brother Hubert. According to Georges Hulin de Loo, Hand G's contributions to the Turin-Milan Hours "constitute the most marvelous group of paintings that have ever decorated any book, and, for their period, the most astounding work known to the history of art".Jan van Eyck's use of oil as a medium was a significant development, allowing artists far greater manipulation of paint. The 16th-century art historian Giorgio Vasari claimed van Eyck invented the use of oil paint; a claim that, while exaggerated, indicates the extent to which van Eyck helped disseminate the technique. Van Eyck employed a new level of virtuosity, mainly from taking advantage of the fact that oil dries so slowly; this gave him more time and more scope for blending and mixing layers of different pigments, and his technique was quickly adopted and refined by both Robert Campin and Rogier van der Weyden. These three artists are considered the first rank and most influential of the early generation of Early Netherlandish painters. Their influence was felt across northern Europe, from Bohemia and Poland in the east to Austria and Swabia in the south. 
Question: What are the last names of the three artists who are considered the first rank and most influential of the early generation of Early Netherlandish painters?
[EX A]: Van Eyck.

[EX Q]: Passage: Following a fire at the Ajuda Palace in 1794, the Prince Regent John VI and his wife Carlotta Joaquina began to use Queluz themselves. The Robillon wing was enlarged and given an upper floor for the use of the princess and her nine children. These additions were destroyed in the fire of 1934. To escape the forces of Napoleon I in 1807, the Portuguese royal family abandoned Queluz and fled to Brazil. The French occupational forces took control of the palace, and their commander, General Junot, made several alterations to the building. On the royal family's return from exile in 1821, the King preferred to live at Mafra, leaving his wife, the Spanish Queen Carlotta Joaquina, to occupy Queluz with her aunt Princess Maria Francisca Benedita. The King visited Queluz infrequently. It was on one of these rare visits that João VI died in the circular domed King's Bedroom in 1826.Carlotta Joaquina, sometimes described as sinister, is said to have been ambitious and violent. Her features were reportedly ugly, and she was short in stature. Whatever her shortcomings she lived in great style at Queluz, employing an orchestra which William Beckford described as the finest in Europe. The Queen also had a small private theatre in the gardens, of which nothing remains today. She died at the palace in 1830.Following the death of Carlotta Joaquina, Queluz saw only intermittent use as a royal residence and was not again the primary residence of Portuguese royalty. Carlotta Joaquina's son King Miguel used the palace during the three-year civil war which he fought against his brother King Pedro IV, before being forced by his brother in 1834 to abdicate and go into exile. A year later, Pedro IV died of tuberculosis at the age of 35 at Queluz, the palace of his birth. Pedro I's daughter Maria II ruled until her death in 1853 and was succeeded by her son Pedro V. Following his untimely death in the cholera epidemic of 1861, the throne passed to his brother Luís. From this time the royal family lived chiefly at the rebuilt Ajuda Palace in Lisbon. On the assassination of Luís' son Carlos I in 1908, the palace passed into the ownership of the state. Portugal was in the turmoil of revolution and the monarchy fell two years later. 
Question: What are the full names of the people who died at the palace?
[EX A]: Carlotta Joaquina.
