Question: The Somerset Coal Canal was built in the early 19th century to reduce the cost of transportation of coal and other heavy produce. The first 16 kilometres (10 mi), running from a junction with the Kennet and Avon Canal, along the Cam valley, to a terminal basin at Paulton, were in use by 1805, together with several tramways. A planned 11.7 km (7.3 mi) branch to Midford was never built, but in 1815 a tramway was laid along its towing path. In 1871 the tramway was purchased by the Somerset and Dorset Joint Railway (S&DJR), and operated until the 1950s.
Try to answer this question if possible: In what year were the several tramways completed?

Question: In the 1772 First Partition of Poland, the Prussian king Frederick the Great annexed neighboring Royal Prussia, i.e. the Polish voivodeships of Pomerania (Gdansk Pomerania or Pomerelia), Malbork, Chemno and the Prince-Bishopric of Warmia, thereby bridging the "Polish Corridor" between his Prussian and Farther Pomeranian lands and cutting remaining Poland off the Baltic Coast. The territory of Warmia was incorporated into the lands of former Ducal Prussia, which, by administrative deed of 31 January 1773 were named East Prussia. The former Polish Pomerelian lands beyond the Vistula River together with Malbork and Chemno Land formed the Province of West Prussia with its capital at Marienwerder (Kwidzyn). The Polish Partition Sejm ratified the cession on 30 September 1773, whereafter Frederick officially went on to call himself a King "of" Prussia.

Question: In the 16th century, Count Hieronymus Schlick of Bohemia began minting coins known as Joachimstalers (from German thal, or nowadays usually Tal, "valley", cognate with "dale" in English), named for Joachimstal, the valley where the silver was mined (St. Joachim's Valley, now Jachymov; then part of the Kingdom of Bohemia, now part of the Czech Republic). Joachimstaler was later shortened to the German Taler, a word that eventually found its way into Danish and Swedish as daler, Norwegian as dalar and daler, Dutch as daler or daalder, Ethiopian as (talari), Hungarian as taller, Italian as tallero, and English as dollar. Alternatively, thaler is said to come from the German coin Guldengroschen ("great guilder", being of silver but equal in value to a gold guilder), minted from the silver from Joachimsthal.
Try to answer this question if possible: Other than "taler" what is the other name of the Italian coin?

Question: The Brazilian federal constitution states that the power to enter into treaties is vested in the president and that such treaties must be approved by Congress (articles 84, clause VIII, and 49, clause I). In practice, this has been interpreted as meaning that the executive branch is free to negotiate and sign a treaty, but its ratification by the president is contingent upon the prior approval of Congress. Additionally, the Federal Supreme Court has ruled that, following ratification and entry into force, a treaty must be incorporated into domestic law by means of a presidential decree published in the federal register in order to be valid in Brazil and applicable by the Brazilian authorities.
Try to answer this question if possible: What Brazilian institution has ruled that a treaty must be incorporated into domestic law by means of a presidential decree?
Answer:
the Federal Supreme Court
