Which portion of the Nile runs from where they migrate to the country that borders Egypt to the south?
Blue Nile
Title: Ancient Egypt
Passage: Ancient Egypt was a civilization of ancient Northeastern Africa, concentrated along the lower reaches of the Nile River in the place that is now the country Egypt. Egyptian civilization followed prehistoric Egypt and coalesced around 3100 BC (according to conventional Egyptian chronology) with the political unification of Upper and Lower Egypt under Menes (often identified with Narmer). The history of ancient Egypt occurred as a series of stable kingdoms, separated by periods of relative instability known as Intermediate Periods: the Old Kingdom of the Early Bronze Age, the Middle Kingdom of the Middle Bronze Age and the New Kingdom of the Late Bronze Age.
Title: Tekezé River
Passage: The Tekezé River rises in the central Ethiopian Highlands near Mount Qachen within Lasta, from where it flows west, north, then west again, forming the westernmost border of Ethiopia and Eritrea from the confluence of the Tomsa with the Tekezé at to the tripoint between the two countries and Sudan at . After entering northeastern Sudan at the tripoint it joins the Atbarah River, which is a tributary of the Nile. The Tekezé is perhaps the true upper course of the Atbarah, as the former follows the longer course prior to the confluence of the two rivers.
Title: Political history of the world
Passage: The first states of sorts were those of early dynastic Sumer and early dynastic Egypt, which arose from the Uruk period and Predynastic Egypt respectively at approximately 3000BCE. Early dynastic Egypt was based around the Nile River in the north - east of Africa, the kingdom's boundaries being based around the Nile and stretching to areas where oases existed. Early dynastic Sumer was located in southern Mesopotamia with its borders extending from the Persian Gulf to parts of the Euphrates and Tigris rivers.
Title: Sahara
Passage: The desert comprises much of North Africa, excluding the fertile region on the Mediterranean Sea coast, the Atlas Mountains of the Maghreb, and the Nile Valley in Egypt and Sudan. It stretches from the Red Sea in the east and the Mediterranean in the north to the Atlantic Ocean in the west, where the landscape gradually changes from desert to coastal plains. To the south, it is bounded by the Sahel, a belt of semi-arid tropical savanna around the Niger River valley and the Sudan Region of Sub-Saharan Africa.
Title: Arizona State Route 189
Passage: State Route 189 (SR 189) is a highway in Santa Cruz County, Arizona that runs from its junction with Interstate 19 to the US-Mexico Border. It is a north–south route for its entirety.
Title: Black people
Passage: About 150,000 East African and black people live in Israel, amounting to just over 2% of the nation's population. The vast majority of these, some 120,000, are Beta Israel, most of whom are recent immigrants who came during the 1980s and 1990s from Ethiopia. In addition, Israel is home to over 5,000 members of the African Hebrew Israelites of Jerusalem movement that are descendants of African Americans who emigrated to Israel in the 20th century, and who reside mainly in a distinct neighborhood in the Negev town of Dimona. Unknown numbers of black converts to Judaism reside in Israel, most of them converts from the United Kingdom, Canada, and the United States.
Title: Turkey
Passage: Turkey (Turkish: Türkiye (ˈtyɾcije)), officially the Republic of Turkey (Turkish: Türkiye Cumhuriyeti (ˈtyɾcije d͡ʒumˈhuɾijeti) (listen)), is a transcontinental country in Eurasia, located mainly in Western Asia, with a smaller portion on the Balkan peninsula in Southeast Europe. Turkey is bordered by eight countries: Greece and Bulgaria to the northwest; Georgia to the northeast; Armenia, the Azerbaijani exclave of Nakhchivan and Iran to the east; and Iraq and Syria to the south. The country is encircled by seas on three sides, with the Aegean Sea to the west, the Black Sea to the north, and the Mediterranean Sea to the south. The Bosphorus, the Sea of Marmara, and the Dardanelles, which together form the Turkish Straits, divide Thrace and Anatolia and separate Europe from Asia. Ankara is the capital while Istanbul is the country's largest city and main cultural and commercial centre, classified as a leading global city.
Title: Neolithic
Passage: Domestication of sheep and goats reached Egypt from the Near East possibly as early as 6,000 BC. Graeme Barker states "The first indisputable evidence for domestic plants and animals in the Nile valley is not until the early fifth millennium bc in northern Egypt and a thousand years later further south, in both cases as part of strategies that still relied heavily on fishing, hunting, and the gathering of wild plants" and suggests that these subsistence changes were not due to farmers migrating from the Near East but was an indigenous development, with cereals either indigenous or obtained through exchange. Other scholars argue that the primary stimulus for agriculture and domesticated animals (as well as mud-brick architecture and other Neolithic cultural features) in Egypt was from the Middle East.
Title: Lake Timsah
Passage: Lake Timsah, also known as Crocodile Lake, is a lake in Egypt on the Nile delta. It lies in a basin developed along a fault extending from the Mediterranean Sea to the Gulf of Suez through the Bitter Lakes region. In 1800, a flood filled the Wadi Tumilat, which caused Timsah's banks to overflow and moved water south into the Bitter Lakes about nine miles (14 km) away. In 1862, the lake was filled with waters from the Red Sea.
Title: Brazos Mountains
Passage: The Brazos Mountains is a range in far northern Rio Arriba County, in northern New Mexico in the southwestern United States. The range is part of the southern portion of the San Juan Mountains which are more well known in Colorado. A high crest runs from the border with Colorado for over in a south-southeasterly direction. The high point of the range at is on Grouse Mesa,
Title: A13 highway (Nigeria)
Passage: The A13 highway is a highway in Nigeria. It runs from Jimeta on the Benue River in Adamawa State north, close to the eastern border of the country, to join the A4 highway near Bama in Borno State.
Title: Former Region 11 (Johannesburg)
Passage: Region 11 was an administrative district in the city of Johannesburg, South Africa, from 2000 to 2006. On a map, Region 11 appeared to hang down from the borders of the two Soweto regions and Johannesburg South. It was about 40 km south of the Inner City. It was the most isolated, least integrated region of Johannesburg, with its east, west and southern borders also forming Johannesburg’s boundaries in the area. It was diagonally traversed by the N1 and the Golden Highway (both from north-east to south-west), with the N12 (R29) running along its northern border. The region was abolished with a reorganisation of regions in 2006.
Title: Nile
Passage: The Nile (Arabic: النيل‎, written as al-Nīl; pronounced as an-Nīl) is a major north-flowing river in northeastern Africa, and is the longest river in Africa and the disputed longest river in the world (Brazilian government claims that the Amazon River is longer than the Nile). The Nile, which is about 6,650 km (4,130 mi) long, is an "international" river as its drainage basin covers eleven countries, namely, Tanzania, Uganda, Rwanda, Burundi, the Democratic Republic of the Congo, Kenya, Ethiopia, Eritrea, South Sudan, Republic of the Sudan and Egypt. In particular, the Nile is the primary water source of Egypt and Sudan.The river Nile has two major tributaries, the White Nile and Blue Nile. The White Nile is considered to be the headwaters and primary stream of the Nile itself. The Blue Nile, however, is the source of most of the water and silt. The White Nile is longer and rises in the Great Lakes region of central Africa, with the most distant source still undetermined but located in either Rwanda or Burundi. It flows north through Tanzania, Lake Victoria, Uganda and South Sudan.  The Blue Nile begins at Lake Tana in Ethiopia and flows into Sudan from the southeast. The two rivers meet just north of the Sudanese capital of Khartoum.The northern section of the river flows north almost entirely through the Sudanese desert to Egypt, then ends in a large delta and flows into the Mediterranean Sea. Egyptian civilization and Sudanese kingdoms have depended on the river since ancient times. Most of the population and cities of Egypt lie along those parts of the Nile valley north of Aswan, and nearly all the cultural and historical sites of Ancient Egypt are found along river banks.
Title: Egypt
Passage: The First Intermediate Period ushered in a time of political upheaval for about 150 years. Stronger Nile floods and stabilisation of government, however, brought back renewed prosperity for the country in the Middle Kingdom c. 2040 BC, reaching a peak during the reign of Pharaoh Amenemhat III. A second period of disunity heralded the arrival of the first foreign ruling dynasty in Egypt, that of the Semitic Hyksos. The Hyksos invaders took over much of Lower Egypt around 1650 BC and founded a new capital at Avaris. They were driven out by an Upper Egyptian force led by Ahmose I, who founded the Eighteenth Dynasty and relocated the capital from Memphis to Thebes.

It is the world's only contiguous Eurafrasian nation. Most of Egypt's territory of 1,010,408 square kilometres (390,000 sq mi) lies within the Nile Valley. Egypt is a Mediterranean country. It is bordered by the Gaza Strip and Israel to the northeast, the Gulf of Aqaba to the east, the Red Sea to the east and south, Sudan to the south and Libya to the west.
Title: New York City
Passage: Ecuador, Colombia, Guyana, Peru, and Brazil were the top source countries from South America for legal immigrants to the New York City region in 2013; the Dominican Republic, Jamaica, Haiti, and Trinidad and Tobago in the Caribbean; Egypt, Ghana, and Nigeria from Africa; and El Salvador, Honduras, and Guatemala in Central America. Amidst a resurgence of Puerto Rican migration to New York City, this population had increased to approximately 1.3 million in the metropolitan area as of 2013.
Title: Highway M23 (Ukraine)
Passage: Highway M23 is one of the shortest Ukrainian international highway (M-highway) which connects Berehove with Khust and runs in the southern portion of the region next to the Hungarian and Romanian borders.

Title: Egypt
Passage: With over 90 million inhabitants, Egypt is the most populous country in North Africa and the Arab World, the third-most populous in Africa (after Nigeria and Ethiopia), and the fifteenth-most populous in the world. The great majority of its people live near the banks of the Nile River, an area of about 40,000 square kilometres (15,000 sq mi), where the only arable land is found. The large regions of the Sahara desert, which constitute most of Egypt's territory, are sparsely inhabited. About half of Egypt's residents live in urban areas, with most spread across the densely populated centres of greater Cairo, Alexandria and other major cities in the Nile Delta.
