Q: Work commenced on 9 July 1944, and S-50 began partial operation in September. Ferguson operated the plant through a subsidiary known as Fercleve. The plant produced just  of 0.852% uranium-235 in October. Leaks limited production and forced shutdowns over the next few months, but in June 1945 it produced . By March 1945, all 21 production racks were operating. Initially the output of S-50 was fed into Y-12, but starting in March 1945 all three enrichment processes were run in series. S-50 became the first stage, enriching from 0.71% to 0.89%. This material was fed into the gaseous diffusion process in the K-25 plant, which produced a product enriched to about 23%. This was, in turn, fed into Y-12, which boosted it to about 89%, sufficient for nuclear weapons.
How many things were fed into the Y-12
A: 2

Q: The Black Sea Fleet is considered to have been founded by Prince Potemkin on May 13, 1783, together with its principal base, the city of Sevastopol. Formerly commanded by such legendary admirals as Dmitriy Senyavin and Pavel Nakhimov, it is a fleet of enormous historical and political importance for Russia. In 1790, Russian naval forces under the command of Admiral Fyodor Ushakov defeated the Turkish fleet at the Battle of Kerch Strait. From 1841 onward, the fleet was confined to the Black Sea by the London Straits Convention. As a result of the Crimean War, one provision of the Treaty of Paris was that the Black Sea was to be a demilitarized zone like the Island of Åland in the Baltic Sea, although Russia subsequently renounced the treaty and reconstituted its naval strength and fortifications in the Black Sea. The crew of the battleship Potemkin revolted in 1905 soon after the Navy's defeat in the Russo-Japanese War. Lenin wrote that the Potemkin uprising had had a huge importance in terms of being the first attempt at creating the nucleus of a revolutionary army. During World War I, there were a number of encounters between the Russian and Ottoman navies in the Black Sea. The Ottomans initially had the advantage due to their having under their command the German battlecruiser SMS Goeben, but after the two modern Russian dreadnoughts Imperatritsa Mariya and Imperatritsa Ekaterina Velikaya had been built in Mykolaiv, the Russians took command of the sea until the Russian government collapsed in November 1917. German submarines of the Constantinople Flotilla and Turkish light forces would continue to raid and harass Russian shipping until the war's end.
How many years after the founding of the Black Sea Fleet was it confined to the Black Sea by the London Straits Convention?
A: 58

Q: The Livonian War  was fought for control of Old Livonia , when the Tsardom of Russia faced a varying coalition of Denmark-Norway, the Kingdom of Sweden, and the Union  of the Grand Duchy of Lithuania and the Kingdom of Poland. During the period 1558-1578, Russia dominated the region with early military successes at Dorpat  and Narva. Russian dissolution of the Livonian Confederation brought Poland-Lithuania into the conflict, while Sweden and Denmark both intervened between 1559 and 1561. Swedish Estonia was established despite constant invasion from Russia, and Frederick II of Denmark bought the old Bishopric of Ösel-Wiek, which he placed under the control of his brother Magnus of Holstein. Magnus attempted to expand his Livonian holdings to establish the Russian vassal state Kingdom of Livonia, which nominally existed until his defection in 1576. In 1576, Stefan Batory became King of Poland as well as Grand Duke of Lithuania and turned the tide of the war with his successes between 1578 and 1581, including the joint Swedish-Polish-Lithuanian offensive at the Battle of Wenden. This was followed by an extended campaign through Russia culminating in the long and difficult siege of Pskov. Under the 1582 Truce of Jam Zapolski, which ended the war between Russia and Poland-Lithuania, Russia lost all its former holdings in Livonia and Polotsk to Poland-Lithuania. The following year, Sweden and Russia signed the Truce of Plussa with Sweden gaining most of Ingria and northern Livonia while retaining the Duchy of Estonia.
who signed the truce ?
A: Sweden and Russia s
