Question: The ethnic group whose language, according to Xenophon, sounded like Armenian forms what percentage of the population in the world's largest pistachio producing country?

<P0-S0> the exonym armenia is attested in the old persian behistun inscription (515 bc) as armina (    ). <P0-S1> the ancient greek terms ἀρμενία (armenía) and ἀρμένιοι (arménioi, "armenians") are first mentioned by hecataeus of miletus (c. 550 bc – c. 476 bc). <P0-S2> xenophon, a greek general serving in some of the persian expeditions, describes many aspects of armenian village life and hospitality in around 401 bc. <P0-S3> he relates that the people spoke a language that to his ear sounded like the language of the persians. <P0-S4> according to the histories of both moses of chorene and michael chamchian, armenia derives from the name of aram, a lineal descendant of hayk. <SEP> <P1-S0> Historically, the name Armenian has come to internationally designate this group of people. <P1-S1> It was first used by neighbouring countries of ancient Armenia. <P1-S2> The earliest attestations of the exonym Armenia date around the 6th century BC. <P1-S3> In his trilingual Behistun Inscription dated to 517 BC, Darius I the Great of Persia refers to Urashtu (in Babylonian) as Armina (in Old Persian; Armina (    ) and Harminuya (in Elamite). <P1-S4> In Greek, Αρμένιοι "Armenians" is attested from about the same time, perhaps the earliest reference being a fragment attributed to Hecataeus of Miletus (476 BC). <P1-S5> Xenophon, a Greek general serving in some of the Persian expeditions, describes many aspects of Armenian village life and hospitality in around 401 BC. <P1-S6> He relates that the people spoke a language that to his ear sounded like the language of the Persians. <SEP> <P2-S0> these events are described in detail within the behistun inscription. <P2-S1> after the administrative reorganization of the persian empire, armenia was converted into several satrapies. <P2-S2> armenian satraps regularly intermarried with the family of the king of kings. <P2-S3> these satraps provided contingents to xerxes' invasion of greece in 480 bc. <P2-S4> herodotus says that the armenians in the army of xerxes "were armed like the phrygians." <P2-S5> in 401 bc xenophon marched through armenia with a large army of greek mercenaries as part of the march of the ten thousand. <P2-S6> xenophon mentions two individuals by the name orontes, apparently both persian. <P2-S7> one was a nobleman and military officer of high rank, belonging to the royal family; as the commander of the citadel of sardis, he waged war against cyrus the younger and he tried to betray him to artaxerxes ii memnon shortly before the battle of cunaxa, but was taken prisoner and sentenced to death by a court martial. <P2-S8> xenophon's anabasis has a detailed description of the country, where it is also written that the region near the river centrites was defended by the satrap of armenia for artaxerxes ii, named orontes, son of artasyras, who had armenian contingents as well as alarodians. <P2-S9> tiribaz is mentioned as hipparchos (vice-governor) of armenia under orontes, who later became satrap of lydia. <SEP> <P3-S0> Top Pistachio Producers in 2014 Region Production (metric tonnes) Iran 415,531 United States 233,146 Turkey 80,000 China 76,943 World 857,878 <SEP> <P4-S0> The CIA's World Factbook has estimated that around 79% of the population of Iran are a diverse Indo-European ethno-linguistic group that comprise the speakers of Iranian languages, with Persians constituting 53% of the population, Gilaks and Mazanderanis 7%, Kurds 10%, Lurs 6%, and Balochs 2%. <P4-S1> As with the spoken languages, the ethnic group composition also remains a point of debate, mainly regarding the largest and second largest ethnic groups, the Persians and Azerbaijanis, due to the lack of Iranian state censuses based on ethnicity. <P4-S2> Peoples of the other ethnicities in Iran make up the remaining 22%, with Azerbaijanis constituting 16%, Arabs 2%, Turkmens and Turkic tribes 2%, and others 2% (such as Armenians, Talysh, Georgians, Circassians, Assyrians).
