Ex Input:
The Russian Civil War included what non-Russians?, Context: The principal fighting occurred between the Bolshevik Red Army and the forces of the White Army. Many foreign armies warred against the Red Army, notably the Allied Forces, yet many volunteer foreigners fought in both sides of the Russian Civil War. Other nationalist and regional political groups also participated in the war, including the Ukrainian nationalist Green Army, the Ukrainian anarchist Black Army and Black Guards, and warlords such as Ungern von Sternberg. The most intense fighting took place from 1918 to 1920. Major military operations ended on 25 October 1922 when the Red Army occupied Vladivostok, previously held by the Provisional Priamur Government. The last enclave of the White Forces was the Ayano-Maysky District on the Pacific coast. The majority of the fighting ended in 1920 with the defeat of General Pyotr Wrangel in the Crimea, but a notable resistance in certain areas continued until 1923 (e.g., Kronstadt Uprising, Tambov Rebellion, Basmachi Revolt, and the final resistance of the White movement in the Far East).

Ex Output:
volunteer foreigners

What happens with Patent 5,703,999, Context: An exception is the United States, where patents filed prior to 8 June 1995 expire 17 years after the publication date of the patent, but application extensions make it possible for a patent to issue much later than normally expected (see submarine patents). The various MP3-related patents expire on dates ranging from 2007 to 2017 in the U.S. Patents filed for anything disclosed in ISO CD 11172 a year or more after its publication are questionable. If only the known MP3 patents filed by December 1992 are considered, then MP3 decoding has been patent-free in the US since 22 September 2015 when U.S. Patent 5,812,672 expired which had a PCT filing in October 1992. If the longest-running patent mentioned in the aforementioned references is taken as a measure, then the MP3 technology will be patent-free in the United States on 30 December 2017 when U.S. Patent 5,703,999, held by the Fraunhofer-Gesellschaft and administered by Technicolor, expires.

Ex Input:
What does R and D stand for from the text., Context: The Estonian Academy of Sciences is the national academy of science. The strongest public non-profit research institute that carries out fundamental and applied research is the National Institute of Chemical Physics and Biophysics (NICPB; Estonian KBFI). The first computer centres were established in the late 1950s in Tartu and Tallinn. Estonian specialists contributed in the development of software engineering standards for ministries of the Soviet Union during the 1980s. As of 2011[update], Estonia spends around 2.38% of its GDP on Research and Development, compared to an EU average of around 2.0%.

Ex Output:
