It flows out of the Valdai Hills and continues west into the Western Dvina. The town of Nelidovo and the urban-type settlement of Zharkovsky are located along the Mezha. It is long, and the area of its basin . Its main tributaries are the Bereza, the Luchesa, the Obsha, and the Yelsha (all left).

Document 3: Jews: More than half of the Jews live in the Diaspora (see Population table). Currently, the largest Jewish community outside Israel, and either the largest or second-largest Jewish community in the world, is located in the United States, with 5.2 million to 6.4 million Jews by various estimates. Elsewhere in the Americas, there are also large Jewish populations in Canada (315,000), Argentina (180,000-300,000), and Brazil (196,000-600,000), and smaller populations in Mexico, Uruguay, Venezuela, Chile, Colombia and several other countries (see History of the Jews in Latin America). Demographers disagree on whether the United States has a larger Jewish population than Israel, with many maintaining that Israel surpassed the United States in Jewish population during the 2000s, while others maintain that the United States still has the largest Jewish population in the world. Currently, a major national Jewish population survey is planned to ascertain whether or not Israel has overtaken the United States in Jewish population.
Document 4: Han dynasty: During the turbulent reign of Wang Mang, Han lost control over the Tarim Basin, which was conquered by the Northern Xiongnu in AD 63 and used as a base to invade Han's Hexi Corridor in Gansu. Dou Gu (d. 88 AD) defeated the Northern Xiongnu at the Battle of Yiwulu in AD 73, evicting them from Turpan and chasing them as far as Lake Barkol before establishing a garrison at Hami. After the new Protector General of the Western Regions Chen Mu (d. AD 75) was killed by allies of the Xiongnu in Karasahr and Kucha, the garrison at Hami was withdrawn. At the Battle of Ikh Bayan in AD 89, Dou Xian (d. AD 92) defeated the Northern Xiongnu chanyu who then retreated into the Altai Mountains. After the Northern Xiongnu fled into the Ili River valley in AD 91, the nomadic Xianbei occupied the area from the borders of the Buyeo Kingdom in Manchuria to the Ili River of the Wusun people. The Xianbei reached their apogee under Tanshihuai (檀石槐) (d. AD 180), who consistently defeated Chinese armies. However, Tanshihuai's confederation disintegrated after his death.
Document 5: Tikhaya Sosna River: The river has its sources in the eastern part of Belgorod Oblast, on the southeastern slopes of the Central Russian Upland. It flows in a northeasterly direction, and joins the Don some west of the town of Liski in Voronezh Oblast.
Document 6: Israel: The population of Israel, as defined by the Israel Central Bureau of Statistics, was estimated in 2016 to be 8,476,600 people. It is the world's only Jewish-majority state, with 6,345,400 citizens, or 74.9%, being designated as Jewish. The country's second largest group of citizens are denoted as Arabs, numbering 1,760,400 people (including the Druze and most East Jerusalem Arabs). The great majority of Israeli Arabs are Sunni Muslims, with smaller but significant numbers of semi-settled Negev Bedouins; the rest are Christians and Druze. Other far smaller minorities include Maronites, Samaritans, Dom people and Roma, Black Hebrew Israelites, other Sub-Saharan Africans, Armenians, Circassians, Vietnamese boat people, and others. Israel also hosts a significant population of non-citizen foreign workers and asylum seekers from Africa and Asia.
Document 7: Jews: According to a report published in 2014, about 43% of all Jews reside in Israel (6.1 million), and 40% in the United States (5.7 million), with most of the remainder living in Europe (1.4 million) and Canada (0.4 million). These numbers include all those who self-identified as Jews in a socio-demographic study or were identified as such by a respondent in the same household. The exact world Jewish population, however, is difficult to measure. In addition to issues with census methodology, disputes among proponents of halakhic, secular, political, and ancestral identification factors regarding who is a Jew may affect the figure considerably depending on the source.
Document 8: Jews: Western Europe's largest Jewish community, and the third-largest Jewish community in the world, can be found in France, home to between 483,000 and 500,000 Jews, the majority of whom are immigrants or refugees from North African Arab countries such as Algeria, Morocco, and Tunisia (or their descendants). The United Kingdom has a Jewish community of 292,000. In Eastern Europe, there are anywhere from 350,000 to one million Jews living in the former Soviet Union, but exact figures are difficult to establish. In Germany, the 102,000 Jews registered with the Jewish community are a slowly declining population, despite the immigration of tens of thousands of Jews from the former Soviet Union since the fall of the Berlin Wall. Thousands of Israelis also live in Germany, either permanently or temporarily, for economic reasons.
Document 9: Skhodnya River: Skhodnya River (), also known as Sukhodnya, Vkhodnya, Vykhodnya and Vskhodnya is a river in the northwest of Moscow, the second largest tributary (after the Yauza River) of the Moskva River. The length of the Skhodnya is 47 km (5 km in Moscow proper). The area of its basin is 17,2 km² (within the city). The Skhodnya originates near the village of Alabushevo (part of Zelenograd) and flows into the Moskva River near the Tushino Airfield. The Skhodnya River is connected with a derivational canal, which supplies water from the Volga River through the Khimki Reservoir (with the help of the Skhodnenskaya hydroelectric plant) to Moscow for sanitary irrigation.
Document 10: Battle of the Tanais River: The Battle of the Tanais River in 373 AD between the Huns and the Alans, was fought on the traditional border between Asia and Europe. The Huns were victorious.
Document 11: Battle of Adrianople: The Battle of Adrianople (9 August 378), sometimes known as the Battle of Hadrianopolis, was fought between an Eastern Roman army led by the Eastern Roman Emperor Valens and Gothic rebels (largely Thervings as well as Greutungs, non-Gothic Alans, and various local rebels) led by Fritigern. The battle took place in the vicinity of Adrianople, in the Roman province of Thracia (modern Edirne in European Turkey). It ended with an overwhelming victory for the Goths and the death of Emperor Valens.
Document 12: Tura River: The Tura River (), also known as Dolgaya River (Long River, ) is a historically important Siberian river which flows eastward from the central Ural Mountains into the Tobol River, a part of the Ob River basin. The main town on it is Tyumen.
Document 13: Kievan Rus': The expansion of the Rus' put further military and economic pressure on the Khazars, depriving them of territory, tributaries, and trade. In around 890, Oleg waged an indecisive war in the lands of the lower Dniester and Dnieper rivers with the Tivertsi and the Ulichs, who were likely acting as vassals of the Magyars, blocking Rus' access to the Black Sea. In 894, the Magyars and Pechenegs were drawn into the wars between the Byzantines and the Bulgarian Empire. The Byzantines arranged for the Magyars to attack Bulgarian territory from the north, and Bulgaria in turn persuaded the Pechenegs to attack the Magyars from their rear. Boxed in, the Magyars were forced to migrate further west across the Carpathian Mountains into the Hungarian plain, depriving the Khazars of an important ally and a buffer from the Rus'. The migration of the Magyars allowed Rus' access to the Black Sea, and they soon launched excursions into Khazar territory along the sea coast, up the Don river, and into the lower Volga region. The Rus' were raiding and plundering into the Caspian Sea region from 864, with the first large-scale expedition in 913, when they extensively raided Baku, Gilan, Mazandaran and penetrated into the Caucasus.
Document 14: Israel: Israel was established as a homeland for the Jewish people and is often referred to as a Jewish state. The country's Law of Return grants all Jews and those of Jewish ancestry the right to Israeli citizenship. Over three quarters, or 75.5%, of the population are Jews from a diversity of Jewish backgrounds. Around 4% of Israelis (300,000), ethnically defined as "others", are Russian descendants of Jewish origin or family who are not Jewish according to rabbinical law, but were eligible for Israeli citizenship under the Law of Return. Approximately 75% of Israeli Jews are born in Israel, 17% are immigrants from Europe and the Americas, and 8% are immigrants from Asia and Africa (including the Arab World). Jews from Europe and the former Soviet Union and their descendants born in Israel, including Ashkenazi Jews, constitute approximately 50% of Jewish Israelis. Jews who left or fled Arab and Muslim countries and their descendants, including both Mizrahi and Sephardi Jews, form most of the rest of the Jewish population. Jewish intermarriage rates run at over 35% and recent studies suggest that the percentage of Israelis descended from both Sephardi and Ashkenazi Jews increases by 0.5 percent every year, with over 25% of school children now originating from both communities.
Document 15: Battle of Mohi: The Battle of Mohi (today Muhi), also known as Battle of the Sajó River or Battle of the Tisza River (11 April 1241), was the main battle between the Mongol Empire and the Kingdom of Hungary during the Mongol invasion of Europe. It took place at Muhi, southwest of the Sajó River. After the invasion, Hungary lay in ruins. Nearly half of the inhabited places had been destroyed by the invading armies. Around 15–25 percent of the population was lost, mostly in lowland areas, especially in the Great Hungarian Plain, the southern reaches of the Hungarian plain in the area now called the Banat and in southern Transylvania.
