Question: In October 1919, Albert went up to Trinity College, Cambridge, where he studied history, economics and civics for a year. On 4 June 1920, he was created Duke of York, Earl of Inverness and Baron Killarney. He began to take on more royal duties. He represented his father, and toured coal mines, factories, and railyards. Through such visits he acquired the nickname of the "Industrial Prince". His stammer, and his embarrassment over it, together with his tendency to shyness, caused him to appear much less impressive than his older brother, Edward. However, he was physically active and enjoyed playing tennis. He played at Wimbledon in the Men's Doubles with Louis Greig in 1926, losing in the first round. He developed an interest in working conditions, and was President of the Industrial Welfare Society. His series of annual summer camps for boys between 1921 and 1939 brought together boys from different social backgrounds.
Try to answer this question if possible: In what year did Louis Greig begin playing tennis?

Question: Frédéric François Chopin (/ˈʃoʊpæn/; French pronunciation: ​[fʁe.de.ʁik fʁɑ̃.swa ʃɔ.pɛ̃]; 22 February or 1 March 1810 – 17 October 1849), born Fryderyk Franciszek Chopin,[n 1] was a Polish and French (by citizenship and birth of father) composer and a virtuoso pianist of the Romantic era, who wrote primarily for the solo piano. He gained and has maintained renown worldwide as one of the leading musicians of his era, whose "poetic genius was based on a professional technique that was without equal in his generation." Chopin was born in what was then the Duchy of Warsaw, and grew up in Warsaw, which after 1815 became part of Congress Poland. A child prodigy, he completed his musical education and composed his earlier works in Warsaw before leaving Poland at the age of 20, less than a month before the outbreak of the November 1830 Uprising.

Question: Buddhists believe Gautama Buddha was the first to achieve enlightenment in this Buddha era and is therefore credited with the establishment of Buddhism. A Buddha era is the stretch of history during which people remember and practice the teachings of the earliest known Buddha. This Buddha era will end when all the knowledge, evidence and teachings of Gautama Buddha have vanished. This belief therefore maintains that many Buddha eras have started and ended throughout the course of human existence.[web 15][web 16] The Gautama Buddha, therefore, is the Buddha of this era, who taught directly or indirectly to all other Buddhas in it (see types of Buddhas).
Try to answer this question if possible: Who taught directly or indirectly to all other Buddhas?
Answer: Gautama Buddha
Question: In Epperson v. Arkansas, 393 U.S. 97 (1968), the Supreme Court considered an Arkansas law that made it a crime "to teach the theory or doctrine that mankind ascended or descended from a lower order of animals," or "to adopt or use in any such institution a textbook that teaches" this theory in any school or university that received public funds. The court's opinion, written by Justice Abe Fortas, ruled that the Arkansas law violated "the constitutional prohibition of state laws respecting an establishment of religion or prohibiting the free exercise thereof. The overriding fact is that Arkansas' law selects from the body of knowledge a particular segment which it proscribes for the sole reason that it is deemed to conflict with a particular religious doctrine; that is, with a particular interpretation of the Book of Genesis by a particular religious group." The court held that the Establishment Clause prohibits the state from advancing any religion, and that "[T]he state has no legitimate interest in protecting any or all religions from views distasteful to them."
