The answer to the question: What was the name of Joseph I's brother's wife? is inside the article: Queluz's architecture is representative of the final extravagant period of Portuguese culture that followed the discovery of Brazilian gold in 1690. From the beginning of the 18th century many foreign artists and architects were employed in Portugal to satisfy the needs of the newly enriched aristocracy; they brought with them classical ideas of architecture which derived from the Renaissance. In its design, Queluz is a revolt against the earlier, heavier, Italian-influenced Baroque which preceded the Rococo style throughout Europe.Comparisons with the far larger and more Baroque Versailles are unwarranted: Versailles is referred to as having "an aura of majesty" and it was built and dedicated to exhibit in stone "all the glories of France," whereas the far smaller palace at Queluz has been described as "exquisite rather than magnificent" and looking like "a very expensive birthday cake". In its frivolity, the architecture of Queluz reflects the lifestyle led by the Portuguese royal family at the time of building: during the reign of Dom Pedro's brother, Joseph I, when Portugal was in practice governed by a valido or favourite, the Marquis of Pombal. Pombal encouraged the royal family to while away their days in the country and leave affairs of state to him. Thus the extravagant, almost whimsical architecture of Queluz, set apart from the capital city, exactly represents the politics and social events of Portugal during this era, and the carefree and flamboyant lives led by its occupants. Queluz's role as a haven for those without responsibility was, however, to be short-lived. On the accession to the throne of Dom Pedro's wife Maria in 1777, Pombal was dismissed, and Dom Pedro and Maria ruled jointly in his place, using the partially completed Rococo palace at Queluz as a retreat from affairs of state in much the same way as Frederick the Great used Europe's other famed Rococo palace, Sanssouci. The site chosen for this summer retreat was in a secluded hollow. It had originally been owned by the Marquis of..., can you guess it ?
Ans: Maria

The answer to the question: How many acres is Bryce Canyon? is inside the article: These scenic areas were first described for the public in magazine articles published by Union Pacific and Santa Fe railroads in 1916. People like Forest Supervisor J. W. Humphrey promoted the scenic wonders of Bryce Canyon's amphitheaters, and by 1918 nationally distributed articles also helped to spark interest. However, poor access to the remote area and the lack of accommodations kept visitation to a bare minimum. Ruby Syrett, Harold Bowman and the Perry brothers later built modest lodging, and set up "touring services" in the area. Syrett later served as the first postmaster of Bryce Canyon. Visitation steadily increased, and by the early 1920s the Union Pacific Railroad became interested in expanding rail service into southwestern Utah to accommodate more tourists. At the same time, conservationists became alarmed by the damage overgrazing, logging, and unregulated visitation were having on the fragile features of Bryce Canyon. A movement to have the area protected was soon started, and National Park Service Director Stephen Mather responded by proposing that Bryce Canyon be made into a state park. The governor of Utah and the Utah State Legislature, however, lobbied for national protection of the area. Mather relented and sent his recommendation to President Warren G. Harding, who on June 8, 1923 declared Bryce Canyon a national monument.A road was built the same year on the plateau to provide easy access to outlooks over the amphitheaters. From 1924 to 1925, Bryce Canyon Lodge was built from local timber and stone.Members of the United States Congress started work in 1924 on upgrading Bryce Canyon's protection status from a national monument to a national park in order to establish Utah National Park. A process led by the Utah Parks Company for transferring ownership of private and state-held land in the monument to the federal government started in 1923. The last of the land in the proposed park's borders was sold to the federal government four years later, and on February 25, 1928, the renamed Bryce..., can you guess it ?
Ans: 35,835 acres

The answer to the question: What is the scientific name of the specific mollusk species that are the primary food of the limpkin and the endangered snail kite? is inside the article: Ecosystems in the Everglades have been described as both fragile and resilient. Author Michael Grunwald wrote about the observations of the Everglades' first American visitors: "If the Grand Canyon was a breathtaking painting, the Everglades was a complex drama, and everything in it had a role." An estimated 11,000 species of seed-bearing plants and 400 species of land or water vertebrates live in the Everglades, but slight variations in water levels affect many organisms and reshape land formations. The health and productivity of any ecosystem relies on the number of species present: the loss of one species weakens the entire ecosystem.For example, Florida apple snails (Pomacea paludosa)  are an amphibious fresh water mollusk. They have a single gill and lung, and live on stalks of sawgrass in water depths no more than 20 inches (51 cm). They are the primary food of the endangered snail kite (Rostrhamus sociabilis) and limpkin (Aramus guarauna) as well as the raccoon, otter, and young alligator. Apple snails lay their eggs on sawgrass stalks about 6 inches (15 cm) above the water line, and they are intolerant of being submerged for long periods of time. When the eggs hatch, young snails must enter the water quickly or face death. When water levels are too low or rise too quickly while snail eggs are developing, apple snails do not flourish, affecting the many reptiles, mammals, and birds that feed on them. With regard to the ecology of trophic dynamics, or food chains, the 174 species of invertebrates play a vital role in the Everglades. Crayfish, insects, scorpions, and other invertebrates also support a web of animals., can you guess it ?
