Input: Philadelphia
Irish, Italians, Polish, Germans, English, and Greeks are the largest ethnic European groups in the city. Philadelphia has the second-largest Irish and Italian populations in the United States, after New York City. South Philadelphia remains one of the largest Italian neighborhoods in the country and is home to the Italian Market. The Pennsport neighborhood and Gray's Ferry section of South Philadelphia, home to many Mummer clubs, are well known as Irish neighborhoods. The Kensington section, Port Richmond, and Fishtown have historically been heavily Irish and Polish. Port Richmond is well known in particular as the center of the Polish immigrant and Polish-American community in Philadelphia, and it remains a common destination for Polish immigrants. Northeast Philadelphia, although known for its Irish and Irish-American population, is also home to a large Jewish and Russian population. Mount Airy in Northwest Philadelphia also contains a large Jewish community, while nearby Chestnut Hill is historically known as an Anglo-Saxon Protestant stronghold.

Name the six largest European ethnic groups in the city?
Output: Irish, Italians, Polish, Germans, English, and Greeks

Input: Order of the British Empire
Honorary knighthoods are appointed to citizens of nations where Queen Elizabeth II is not Head of State, and may permit use of post-nominal letters but not the title of Sir or Dame. Occasionally honorary appointees are, incorrectly, referred to as Sir or Dame - Bill Gates or Bob Geldof, for example. Honorary appointees who later become a citizen of a Commonwealth realm can convert their appointment from honorary to substantive, then enjoy all privileges of membership of the order including use of the title of Sir and Dame for the senior two ranks of the Order. An example is Irish broadcaster Terry Wogan, who was appointed an honorary Knight Commander of the Order in 2005 and on successful application for dual British and Irish citizenship was made a substantive member and subsequently styled as "Sir Terry Wogan KBE".

Who are examples of Sir of Dame?
Output: Bill Gates or Bob Geldof

Input: God
Stephen Hawking and co-author Leonard Mlodinow state in their book, The Grand Design, that it is reasonable to ask who or what created the universe, but if the answer is God, then the question has merely been deflected to that of who created God. Both authors claim however, that it is possible to answer these questions purely within the realm of science, and without invoking any divine beings. Neuroscientist Michael Nikoletseas has proposed that questions of the existence of God are no different from questions of natural sciences. Following a biological comparative approach, he concludes that it is highly probable that God exists, and, although not visible, it is possible that we know some of his attributes.

Who says the that whether there is or isn't a God are just like questions in natural science?
Output: Michael Nikoletseas

Input: Digestion
Different phases of digestion take place including: the cephalic phase , gastric phase, and intestinal phase. The cephalic phase occurs at the sight, thought and smell of food, which stimulate the cerebral cortex. Taste and smell stimuli are sent to the hypothalamus and medulla oblongata. After this it is routed through the vagus nerve and release of acetylcholine. Gastric secretion at this phase rises to 40% of maximum rate. Acidity in the stomach is not buffered by food at this point and thus acts to inhibit parietal (secretes acid) and G cell (secretes gastrin) activity via D cell secretion of somatostatin. The gastric phase takes 3 to 4 hours. It is stimulated by distension of the stomach, presence of food in stomach and decrease in pH. Distention activates long and myenteric reflexes. This activates the release of acetylcholine, which stimulates the release of more gastric juices. As protein enters the stomach, it binds to hydrogen ions, which raises the pH of the stomach. Inhibition of gastrin and gastric acid secretion is lifted. This triggers G cells to release gastrin, which in turn stimulates parietal cells to secrete gastric acid. Gastric acid is about 0.5% hydrochloric acid (HCl), which lowers the pH to the desired pH of 1-3. Acid release is also triggered by acetylcholine and histamine. The intestinal phase has two parts, the excitatory and the inhibitory. Partially digested food fills the duodenum. This triggers intestinal gastrin to be released. Enterogastric reflex inhibits vagal nuclei, activating sympathetic fibers causing the pyloric sphincter to tighten to prevent more food from entering, and inhibits local reflexes.

How is the gastric phase stimulated to start?
Output:
by distension of the stomach, presence of food in stomach and decrease in pH
