Input: Read this: During the 18th century, systems of plant identification were developed comparable to dichotomous keys, where unidentified plants are placed into taxonomic groups (e.g. family, genus and species) by making a series of choices between pairs of characters. The choice and sequence of the characters may be artificial in keys designed purely for identification (diagnostic keys) or more closely related to the natural or phyletic order of the taxa in synoptic keys. By the 18th century, new plants for study were arriving in Europe in increasing numbers from newly discovered countries and the European colonies worldwide. In 1753 Carl von Linné (Carl Linnaeus) published his Species Plantarum, a hierarchical classification of plant species that remains the reference point for modern botanical nomenclature. This established a standardised binomial or two-part naming scheme where the first name represented the genus and the second identified the species within the genus. For the purposes of identification, Linnaeus's Systema Sexuale classified plants into 24 groups according to the number of their male sexual organs. The 24th group, Cryptogamia, included all plants with concealed reproductive parts, mosses, liverworts, ferns, algae and fungi.
Question: What is the meaning of dichotomous keys?

Output: choices between pairs


QUES: For those that remained under the Ottoman Empire's millet system, religion was the defining characteristic of national groups (milletler), so the exonym "Greeks" (Rumlar from the name Rhomaioi) was applied by the Ottomans to all members of the Orthodox Church, regardless of their language or ethnic origin. The Greek speakers were the only ethnic group to actually call themselves Romioi, (as opposed to being so named by others) and, at least those educated, considered their ethnicity (genos) to be Hellenic. There were, however, many Greeks who escaped the second-class status of Christians inherent in the Ottoman millet system, according to which Muslims were explicitly awarded senior status and preferential treatment. These Greeks either emigrated, particularly to their fellow Greek Orthodox protector, the Russian Empire, or simply converted to Islam, often only very superficially and whilst remaining crypto-Christian. The most notable examples of large-scale conversion to Turkish Islam among those today defined as Greek Muslims - excluding those who had to convert as a matter of course on being recruited through the devshirme - were to be found in Crete (Cretan Turks), Greek Macedonia (for example among the Vallahades of western Macedonia), and among Pontic Greeks in the Pontic Alps and Armenian Highlands. Several Ottoman sultans and princes were also of part Greek origin, with mothers who were either Greek concubines or princesses from Byzantine noble families, one famous example being sultan Selim the Grim, whose mother Gülbahar Hatun was a Pontic Greek.

Likewise the migration of Spanish-speaking Nicaraguans also began as a result of political instability during the end of the 1970s and the 1980s. The uprising of the Sandinista revolution which toppled the Somoza dictatorship in 1979 caused many Nicaraguans to migrate particularly from those opposing the Sandinistas. Throughout the 1980s with the United States supported Contra War (or Contra-revolutionary war) which continued up until 1988, and the economic collapse of the country many more Nicaraguans migrated to the United States amongst other countries. The states of the United States where most Nicaraguans migrated to include Florida, California and Texas.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When did the Nicaraguans arrive?
Ah, so.. Throughout the 1980s with the United States supported Contra War (or Contra-revolutionary war) which continued up until 1988


Question: "Hanover" is the traditional English spelling. The German spelling (with a double n) is becoming more popular in English; recent editions of encyclopedias prefer the German spelling, and the local government uses the German spelling on English websites. The English pronunciation /ˈhænəvər/, with stress on the first syllable and a reduced second syllable, is applied to both the German and English spellings, which is different from German pronunciation [haˈnoːfɐ], with stress on the second syllable and a long second vowel. The traditional English spelling is still used in historical contexts, especially when referring to the British House of Hanover.
Try to answer this question if possible: Which version of the spelling of Hanover does the local Government use on English websites?
Answer: German


Input: Read this: Greece played a peripheral role in the war. When Russia attacked the Ottoman Empire in 1853, King Otto of Greece saw an opportunity to expand North and South into Ottoman areas that had large Greek Christian majorities. However, Greece did not coordinate its plans with Russia, did not declare war, and received no outside military or financial support. Greece, an Orthodox nation, had considerable support in Russia, but the Russian government decided it was too dangerous to help Greece expand its holdings.:32–40 When the Russians invaded the Principalities, the Ottoman forces were tied down so Greece invaded Thessaly and Epirus. To block further Greek moves, the British and French occupied the main Greek port at Piraeus from April 1854 to February 1857, and effectively neutralized the Greek army. Greeks, gambling on a Russian victory, incited the large-scale Epirus Revolt of 1854 as well as uprisings in Crete. The insurrections were failures that were easily crushed by the Ottoman army. Greece was not invited to the peace conference and made no gains out of the war.:139 The frustrated Greek leadership blamed the King for failing to take advantage of the situation; his popularity plunged and he was later forced to abdicate.
Question: Who stirred up the Epirus Revolt of 1854?

Output:
Greeks
