The other independent national television channels are TV3, 3e, UTV Ireland and TG4, the latter of which is a public service broadcaster for speakers of the Irish language. All these channels are available on Saorview, the national free-to-air digital terrestrial television service. Additional channels included in the service are RTÉ News Now, RTÉjr, and RTÉ One +1. Subscription-based television providers operating in Ireland include Virgin Media and Sky. Supported by the Irish Film Board, the Irish film industry grew significantly since the 1990s, with the promotion of indigenous films as well as the attraction of international productions like Braveheart and Saving Private Ryan. A large number of regional and local radio stations are available countrywide. A survey showed that a consistent 85% of adults listen to a mixture of national, regional and local stations on a daily basis. RTÉ Radio operates four national stations, Radio 1, 2fm, Lyric fm, and RnaG. It also operates four national DAB radio stations. There are two independent national stations: Today FM and Newstalk. Ireland has a traditionally competitive print media, which is divided into daily national newspapers and weekly regional newspapers, as well as national Sunday editions. The strength of the British press is a unique feature of the Irish print media scene, with the availability of a wide selection of British published newspapers and magazines. Eurostat reported that 82% of Irish households had Internet access in 2013 compared to the EU average of 79% but only 67% had broadband access.

Problem: The Black Sea Fleet  is the fleet of the Russian Navy in the Black Sea, the Sea of Azov and the Mediterranean Sea. The fleet is considered to have been founded by Prince Potemkin on May 13, 1783. In 1918, the fleet was inherited by the Russian SFSR then the Soviet Union in 1922, where it became part of the Soviet Navy. Following the collapse of the Soviet Union in 1991, the Black Sea Fleet and most of its vessels were inherited by the Russian Federation. The Black Sea Fleet's official primary headquarters and facilities are located in the city of Sevastopol, which is de jure part of Ukraine but de facto part of Russia . The remainder of the fleet's facilities are based in various locations on the Black Sea and the Sea of Azov, including Krasnodar Krai, Rostov Oblast and Crimea. The current commander is Admiral Aleksandr Viktorovich Vitko, who has held the position since April 2013.

The Black Sea Fleet covers how many seas for Russia?

Problem: The US had a gold stock of 1.9 million ounces (59 t) in 1862. Stocks rose to 2.6 million ounces (81 t) in 1866, declined in 1875 to 1.6 million ounces (50 t) and rose to 2.5 million ounces (78 t) in 1878. Net exports did not mirror that pattern. In the decade before the Civil War net exports were roughly constant; postwar they varied erratically around pre-war levels, but fell significantly in 1877 and became negative in 1878 and 1879. The net import of gold meant that the foreign demand for American currency to purchase goods, services, and investments exceeded the corresponding American demands for foreign currencies. In the final years of the greenback period (1862-1879), gold production increased while gold exports decreased.  The decrease in gold exports was considered by some to be a result of changing monetary conditions. The demands for gold during this period were as a speculative vehicle, and for its primary use in the foreign exchange markets financing international trade. The major effect of the increase in gold demand by the public and Treasury was to reduce exports of gold and increase the Greenback price of gold relative to purchasing power.

Was the gold stock of the United States higher in 1866 or 1878?
Answer: 

Problem: The Dano-Hanseatic War from 1426-1435  was an armed trade conflict between the Danish dominated Kalmar Union  and the German Hanseatic League  led by the Free City of Lübeck. When Danish king Eric opened the Baltic trade routes for Dutch ships and introduced a new toll for all foreign ships passing the Øresund , six Hanseatic cities  declared war, put a naval blockade on Scandinavian harbours and allied with Eric's enemy Henry IV, count of Holstein. Therefore the war was intensively linked with the Dutch-Hanseatic War , the Kalmar War with Holstein  and the Swedish revolt . After years of changing fortune in warfare Rostock and Stralsund signed a separate peace agreement in 1430. Lübeck, Hamburg, Wismar and Lüneburg, however, continued the war and assisted Holstein to conquer Flensburg in 1431. Thereafter they agreed an armistice in 1432 and started peace negotiations. Meanwhile an anti-Danish revolt broke out in Sweden . In 1434 Eric had to agree an armistice with the Swedes, too. In April 1435 he signed the peace of Vordingborg with the Hanseatic League and Holstein, followed by the peace of Stockholm with Sweden a few months later the same year. The Hanseatic cities were excepted from the Sound Dues but they had to accept Dutch competition in the Baltic trade. The Danish Duchy of Schleswig was ceded to the count of Holstein. Sweden's autonomous rights and privileges were extended. These peace agreements weakened Eric's position dramatically, and in 1439 he got dethroned by Danish, Swedish and Norwegian Privy Councils.

How many years span these events?
