QUES: The Palácio da Alvorada is the official residence of the President of Brazil. The palace was designed, along with the rest of the city of Brasília, by Oscar Niemeyer and inaugurated in 1958. One of the first structures built in the republic's new capital city, the "Alvorada" lies on a peninsula at the margins of Lake Paranoá. The principles of simplicity and modernity, that in the past characterized the great works of architecture, motivated Niemeyer. The viewer has an impression of looking at a glass box, softly landed on the ground with the support of thin external columns. The building has an area of 7,000 m2 with three floors consisting of the basement, landing, and second floor. The auditorium, kitchen, laundry, medical center, and administration offices are at basement level. The rooms used by the presidency for official receptions are on the landing. The second floor has four suites, two apartments, and various private rooms which make up the residential part of the palace. The building also has a library, a heated Olympic-sized swimming pool, a music room, two dining rooms and various meeting rooms. A chapel and heliport are in adjacent buildings.

QUES: At about this time the surrounding areas experienced recurring fragmentation and reincorporations among a number of feudal secular and ecclesiastical lordships, a common process in the Holy Roman Empire. Alsace experienced great prosperity during the 12th and 13th centuries under Hohenstaufen emperors. Frederick I set up Alsace as a province (a procuratio, not a provincia) to be ruled by ministeriales, a non-noble class of civil servants. The idea was that such men would be more tractable and less likely to alienate the fief from the crown out of their own greed. The province had a single provincial court (Landgericht) and a central administration with its seat at Hagenau. Frederick II designated the Bishop of Strasbourg to administer Alsace, but the authority of the bishop was challenged by Count Rudolf of Habsburg, who received his rights from Frederick II's son Conrad IV. Strasbourg began to grow to become the most populous and commercially important town in the region. In 1262, after a long struggle with the ruling bishops, its citizens gained the status of free imperial city. A stop on the Paris-Vienna-Orient trade route, as well as a port on the Rhine route linking southern Germany and Switzerland to the Netherlands, England and Scandinavia, it became the political and economic center of the region. Cities such as Colmar and Hagenau also began to grow in economic importance and gained a kind of autonomy within the "Decapole" or "Dekapolis", a federation of ten free towns.
During which century did Frederick I make Alsace a province?

The standard SNES controller adds two additional face buttons (X and Y) to the design of the NES iteration, arranging the four in a diamond shape, and introduces two shoulder buttons. It also features an ergonomic design by Lance Barr, later used for the NES-102 model controllers, also designed by Barr. The Japanese and PAL region versions incorporate the colors of the four action buttons into system's logo. The North American version's buttons are colored to match the redesigned console; the X and Y buttons are lavender with concave faces, and the A and B buttons are purple with convex faces. Several later consoles derive elements of their controller design from the SNES, including the PlayStation, Dreamcast, Xbox, and Wii Classic Controller.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What color are the shoulder buttons X and Y in Japan?
Ah, so.. unanswerable


Question: There is no clear mechanism by which these local trade organisations became today's Masonic Lodges, but the earliest rituals and passwords known, from operative lodges around the turn of the 17th–18th centuries, show continuity with the rituals developed in the later 18th century by accepted or speculative Masons, as those members who did not practice the physical craft came to be known. The minutes of the Lodge of Edinburgh (Mary's Chapel) No. 1 in Scotland show a continuity from an operative lodge in 1598 to a modern speculative Lodge. It is reputed to be the oldest Masonic Lodge in the world.
Try to answer this question if possible: What is the oldest Masonic lodge in the world?
Answer: Lodge of Edinburgh (Mary's Chapel) No. 1 in Scotland
