Question: The people whose language Xenophon said sounded like Armenian make up what percentage of the population of the country where Kaboud-val is found?

full_context: Document 1: Armenians: Eric P. Hamp in his 2012 Indo-European family tree, groups the Armenian language along with Greek and Ancient Macedonian ("Helleno-Macedonian") in the Pontic Indo-European (also called Helleno-Armenian) subgroup. In Hamp's view the homeland of this subgroup is the northeast coast of the Black Sea and its hinterlands. He assumes that they migrated from there southeast through the Caucasus with the Armenians remaining after Batumi while the pre-Greeks proceeded westwards along the southern coast of the Black Sea.
Document 2: Armenians: Historically, the name Armenian has come to internationally designate this group of people. It was first used by neighbouring countries of ancient Armenia. The earliest attestations of the exonym Armenia date around the 6th century BC. 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). 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). Xenophon, a Greek general serving in some of the Persian expeditions, describes many aspects of Armenian village life and hospitality in around 401 BC. He relates that the people spoke a language that to his ear sounded like the language of the Persians.
Document 3: Iranian languages: The multitude of Middle Iranian languages and peoples indicate that great linguistic diversity must have existed among the ancient speakers of Iranian languages. Of that variety of languages/dialects, direct evidence of only two have survived. These are:
Document 4: Golestan Province: Golestān Province (Persian: استان گلستان‎, Ostān-e Golestān) is one of the 31 provinces of Iran, located in the north-east of the country south of the Caspian Sea. Its capital is Gorgan.
Document 5: Kaboud-val: Kaboud-val waterfall ( Persian: آبشار کبودوال ) also transliterated Kaboud vâl, is a waterfall in Iran's Golestan province. It is near the Aliabad-e katul city about 3 kilometers to the south.
Document 6: Margoon Waterfall: Margoon (Margun) Waterfall is located in the Fars province of Iran near the city of Sepidan. Its name means in Persian "snake like".
Document 7: Cascade Falls (Kettle River): Cascade Falls is a waterfall on the Kettle River in the Boundary Country of the Southern Interior of British Columbia. They are located just south of Christina Lake and just north of the Canada–United States border in a gorge 200-300 yards long and just below the railway bridge over the Kettle by the southern mainline of the Canadian Pacific Railway. The ghost town of Cascade City aka Cascade is nearby and was named for the falls, even though they were not officially named until 1977.
Document 8: Iran: 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. 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%. 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).
Document 9: Orontid dynasty: These events are described in detail within the Behistun inscription. After the administrative reorganization of the Persian Empire, Armenia was converted into several satrapies. Armenian satraps regularly intermarried with the family of the King of Kings. These satraps provided contingents to Xerxes' invasion of Greece in 480 BC. Herodotus says that the Armenians in the army of Xerxes "were armed like the Phrygians."  In 401 BC Xenophon marched through Armenia with a large army of Greek mercenaries as part of the March of the Ten Thousand. Xenophon mentions two individuals by the name Orontes, apparently both Persian. 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. 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. Tiribaz is mentioned as hipparchos (vice-governor) of Armenia under Orontes, who later became satrap of Lydia.
Document 10: Armenians: The first geographical entity that was called Armenia by neighboring peoples (such as by Hecataeus of Miletus and on the Achaemenid Behistun Inscription) was established in the late 6th century BC under the Orontid dynasty within the Achaemenid Persian Empire as part of the latters' territories, and which later became a kingdom. At its zenith (95–65 BC), the state extended from the Caucasus all the way to what is now central Turkey, Lebanon, and northern Iran. The imperial reign of Tigranes the Great is thus the span of time during which Armenia itself conquered areas populated by other peoples.
Document 11: Abshir Ata Waterfall: Abshir Ata Waterfall is a geological reserve at Abshir Say River in Nookat District of Osh Province of Kyrgyzstan. It was established in 1975. The waterfall is the mouth of an underground river. The water cascades down in two steps (15 m and 12 m) through 1.5 m cave in a sheer cliff.
Document 12: Demographics of Eritrea: The nation has nine recognized ethnic groups. According to SIL Ethnologue, Tigrayans make up about 50% of the population; the Tigre, who also speak a Semitic language, constitute around 30% of residents. Most of the rest of the population belong to other Afro - Asiatic - speaking communities of the Cushitic branch. Additionally, there are a number of Nilo - Saharan - speaking ethnic minorities and other smaller groups.
Document 13: Armenia: The exonym Armenia is attested in the Old Persian Behistun Inscription (515 BC) as Armina (    ). The ancient Greek terms Ἀρμενία (Armenía) and Ἀρμένιοι (Arménioi, "Armenians") are first mentioned by Hecataeus of Miletus (c. 550 BC – c. 476 BC). Xenophon, a Greek general serving in some of the Persian expeditions, describes many aspects of Armenian village life and hospitality in around 401 BC. He relates that the people spoke a language that to his ear sounded like the language of the Persians. According to the histories of both Moses of Chorene and Michael Chamchian, Armenia derives from the name of Aram, a lineal descendant of Hayk.
Document 14: Iran: Other non-governmental estimations regarding the groups other than the Persians and Azerbaijanis roughly congruate with the World Factbook and the Library of Congress. However, many scholarly and organisational estimations regarding the number of these two groups differ significantly from the mentioned census. According to many of them, the number of ethnic Azerbaijanis in Iran comprises between 21.6–30% of the total population, with the majority holding it on 25%.cd In any case, the largest population of Azerbaijanis in the world live in Iran.
Document 15: Persians: The Persians are an Iranian ethnic group that make up over half the population of Iran. They share a common cultural system and are native speakers of the Persian language, as well as closely related languages.
