Please answer this: Extract the answer to the question from the following context. Question: How does duramen respond to rot? Context: Heartwood (or duramen) is wood that as a result of a naturally occurring chemical transformation has become more resistant to decay. Heartwood formation occurs spontaneously (it is a genetically programmed process). Once heartwood formation is complete, the heartwood is dead. Some uncertainty still exists as to whether heartwood is truly dead, as it can still chemically react to decay organisms, but only once.

Problem: Given the question: Extract the answer to the question from the following context. Question: How did Africans and Indigenous Americans get so close? Context: European colonists created treaties with Indigenous American tribes requesting the return of any runaway slaves. For example, in 1726, the British governor of New York exacted a promise from the Iroquois to return all runaway slaves who had joined them. This same promise was extracted from the Huron Nation in 1764, and from the Delaware Nation in 1765, though there is no record of slaves ever being returned. Numerous advertisements requested the return of African Americans who had married Indigenous Americans or who spoke an Indigenous American language. The primary exposure that Africans and Indigenous Americans had to each other came through the institution of slavery. Indigenous Americans learned that Africans had what Indigenous Americans considered 'Great Medicine' in their bodies because Africans were virtually immune to the Old-World diseases that were decimating most native populations. Because of this, many tribes encouraged marriage between the two groups, to create stronger, healthier children from the unions.

input question: Extract the answer to the question from the following context. Question: Who initiated the patent investigation? Context: The question of priority for the variable resistance feature of the telephone was raised by the examiner before he approved Bell's patent application. He told Bell that his claim for the variable resistance feature was also described in Gray's caveat. Bell pointed to a variable resistance device in Bell's previous application in which Bell described a cup of mercury, not water. Bell had filed the mercury application at the patent office a year earlier on February 25, 1875, long before Elisha Gray described the water device. In addition, Gray abandoned his caveat, and because he did not contest Bell's priority, the examiner approved Bell's patent on March 3, 1876. Gray had reinvented the variable resistance telephone, but Bell was the first to write down the idea and the first to test it in a telephone.???
output answer: the examiner
Extract the answer to the question from the following context. Question: How many times were people sent forth from Russia? Context: Two rounds of Soviet purges directed by Moscow (19271934 and 19371938) resulted in the expulsion of nearly 10,000 people, from all levels of the Communist Party of Tajikistan. Ethnic Russians were sent in to replace those expelled and subsequently Russians dominated party positions at all levels, including the top position of first secretary. Between 1926 and 1959 the proportion of Russians among Tajikistan's population grew from less than 1% to 13%. Bobojon Ghafurov, Tajikistan's First Secretary of the Communist Party of Tajikistan from 19461956 was the only Tajikistani politician of significance outside of the country during the Soviet Era. He was followed in office by Tursun Uljabayev (195661), Jabbor Rasulov (19611982), and Rahmon Nabiyev (19821985, 19911992).

Q: Extract the answer to the question from the following context. Question: If someone in America uses the word "evangelical", of what are they speaking? Context: During the Reformation, the term was hardly used outside of the German politics. The word evangelical (German: evangelisch), which refers to the gospel, was much more widely used for those involved in the religious movement. Nowadays, this word is still preferred among some of the historical Protestant denominations, above all the ones in the German-speaking area such as the EKD. The German word evangelisch means Protestant, and is different from the German evangelikal, which refers to churches shaped by Evangelicalism. The English word evangelical usually refers to Evangelical Protestant churches, and therefore not to Protestantism as a whole. It traces its roots back to the Puritans in England, where Evangelicalism originated, and then was brought to the United States. The word reformatorisch is used as an alternative for evangelisch in German, and is different from English reformed (German: reformiert), which refers to churches shaped by ideas of John Calvin, Huldrych Zwingli and other Reformed theologians.
A:
Evangelical Protestant churches
