Problem: Josip Broz Tito:

As the President, Tito had access to extensive (state-owned) property associated with the office, and maintained a lavish lifestyle. In Belgrade he resided in the official residence, the Beli dvor, and maintained a separate private home. The Brijuni islands were the site of the State Summer Residence from 1949 on. The pavilion was designed by Joze Plecnik, and included a zoo. Close to 100 foreign heads of state were to visit Tito at the island residence, along with film stars such as Elizabeth Taylor, Richard Burton, Sophia Loren, Carlo Ponti, and Gina Lollobrigida.

Problem: In 1870, at age 23, Bell, his brother's widow, Caroline (Margaret Ottaway), and his parents travelled on the SS Nestorian to Canada. After landing at Quebec City the Bells transferred to another steamer to Montreal and then boarded a train to Paris, Ontario, to stay with the Reverend Thomas Henderson, a family friend. After a brief stay with the Hendersons, the Bell family purchased a farm of 10.5 acres (42,000 m2) at Tutelo Heights (now called Tutela Heights), near Brantford, Ontario. The property consisted of an orchard, large farm house, stable, pigsty, hen-house, and a carriage house, which bordered the Grand River.[N 9]
In what Canadian city did Bell first arrive?

Knowledge, for Popper, was objective, both in the sense that it is objectively true (or truthlike), and also in the sense that knowledge has an ontological status (i.e., knowledge as object) independent of the knowing subject (Objective Knowledge: An Evolutionary Approach, 1972). He proposed three worlds: World One, being the physical world, or physical states; World Two, being the world of mind, or mental states, ideas, and perceptions; and World Three, being the body of human knowledge expressed in its manifold forms, or the products of the second world made manifest in the materials of the first world (i.e., books, papers, paintings, symphonies, and all the products of the human mind). World Three, he argued, was the product of individual human beings in exactly the same sense that an animal path is the product of individual animals, and that, as such, has an existence and evolution independent of any individual knowing subjects. The influence of World Three, in his view, on the individual human mind (World Two) is at least as strong as the influence of World One. In other words, the knowledge held by a given individual mind owes at least as much to the total accumulated wealth of human knowledge, made manifest, as to the world of direct experience. As such, the growth of human knowledge could be said to be a function of the independent evolution of World Three. Many contemporary philosophers, such as Daniel Dennett, have not embraced Popper's Three World conjecture, due mostly, it seems, to its resemblance to mind-body dualism.
What constituted World Four in Popper's theory?
A: unanswerable

Context and question: As one of their first acts after end of the War of the Castilian Succession in 1479, Ferdinand and Isabella established the centrally organized and efficient Holy Brotherhood (Santa Hermandad) as a national police force.

Answer: Holy Brotherhood

The Trans-Alaska Pipeline can transport and pump up to 2.1 million barrels (330,000 m3) of crude oil per day, more than any other crude oil pipeline in the United States. Additionally, substantial coal deposits are found in Alaska's bituminous, sub-bituminous, and lignite coal basins. The United States Geological Survey estimates that there are 85.4 trillion cubic feet (2,420 km3) of undiscovered, technically recoverable gas from natural gas hydrates on the Alaskan North Slope. Alaska also offers some of the highest hydroelectric power potential in the country from its numerous rivers. Large swaths of the Alaskan coastline offer wind and geothermal energy potential as well.
Alaska's coastline also has potential in which three environmentally friendly energy types?
A:
unanswerable
