Document 2: Central African Republic: By 1990, inspired by the fall of the Berlin Wall, a pro-democracy movement arose. Pressure from the United States, France, and from a group of locally represented countries and agencies called GIBAFOR (France, the USA, Germany, Japan, the EU, the World Bank, and the UN) finally led Kolingba to agree, in principle, to hold free elections in October 1992 with help from the UN Office of Electoral Affairs. After using the excuse of alleged irregularities to suspend the results of the elections as a pretext for holding on to power, President Kolingba came under intense pressure from GIBAFOR to establish a "Conseil National Politique Provisoire de la République" (Provisional National Political Council, CNPPR) and to set up a "Mixed Electoral Commission", which included representatives from all political parties.[citation needed]
Document 3: Red Sea: The Red Sea is one of the saltiest bodies of water in the world, owing to high evaporation. Salinity ranges from between ~ 36 ‰ in the southern part because of the effect of the Gulf of Aden water and reaches 41 ‰ in the northern part, owing mainly to the Gulf of Suez water and the high evaporation. The average salinity is 40 ‰. (Average salinity for the world's seawater is ~ 35 ‰ on the Practical Salinity Scale, or PSU; that translates to 3.5% of actual dissolved salts.)
Document 4: Eritrea: In the 1950s, the Ethiopian feudal administration under Emperor Haile Selassie sought to annex Eritrea and Italian Somaliland. He laid claim to both territories in a letter to Franklin D. Roosevelt at the Paris Peace Conference and at the First Session of the United Nations. In the United Nations, the debate over the fate of the former Italian colonies continued. The British and Americans preferred to cede all of Eritrea except the Western province to the Ethiopians as a reward for their support during World War II. The Independence Bloc of Eritrean parties consistently requested from the UN General Assembly that a referendum be held immediately to settle the Eritrean question of sovereignty.
Document 5: Somalis: A referendum was held in neighboring Djibouti (then known as French Somaliland) in 1958, on the eve of Somalia's independence in 1960, to decide whether or not to join the Somali Republic or to remain with France. The referendum turned out in favour of a continued association with France, largely due to a combined yes vote by the sizable Afar ethnic group and resident Europeans. There was also widespread vote rigging, with the French expelling thousands of Somalis before the referendum reached the polls. The majority of those who voted no were Somalis who were strongly in favour of joining a united Somalia, as had been proposed by Mahmoud Harbi, Vice President of the Government Council. Harbi was killed in a plane crash two years later. Djibouti finally gained its independence from France in 1977, and Hassan Gouled Aptidon, a Somali who had campaigned for a yes vote in the referendum of 1958, eventually wound up as Djibouti's first president (1977–1991).
Document 6: Pitch Lake: The Pitch Lake is the largest natural deposit of asphalt in the world, estimated to contain 10 million tons. It is located in La Brea in southwest Trinidad, within the Siparia Regional Corporation. The lake covers about 100 acres and is reported to be 250 feet deep.
Document 7: Somalis: Somali people in the Horn of Africa are divided among different countries (Somalia, Djibouti, Ethiopia, and northeastern Kenya) that were artificially and some might say arbitrarily partitioned by the former imperial powers. Pan-Somalism is an ideology that advocates the unification of all ethnic Somalis once part of Somali empires such as the Ajuran Empire, the Adal Sultanate, the Gobroon Dynasty and the Dervish State under one flag and one nation. The Siad Barre regime actively promoted Pan-Somalism, which eventually led to the Ogaden War between Somalia on one side, and Ethiopia, Cuba and the Soviet Union on the other.
Document 8: Djibouti: Djibouti ( (listen) jih-BOO-tee; Afar: Yibuuti, Arabic: جيبوتي‎ Jībūtī, French: Djibouti, Somali: Jabuuti, officially the Republic of Djibouti) is a country located in the Horn of Africa. It is bordered by Eritrea in the north, Ethiopia in the west and south, and Somalia in the southeast. The remainder of the border is formed by the Red Sea and the Gulf of Aden at the east. Djibouti occupies a total area of 23,200 km2 (8,958 sq mi). The state of Djibouti is predominantly inhabited by two ethnic groups, the Somali and the Afar people, the Somalis being the major ethnic group of the country.
Document 9: Dallol (woreda): Dallol is one of the woredas in the Afar Region of Ethiopia. This woreda is named for the former mining settlement of Dallol, which set the record for the hottest inhabited place on Earth, with an average temperature of 34° C. Located at the northernmost point of the Administrative Zone 2, Dallol's territory includes part of the Afar Depression. This woreda is bordered on the south by Koneba, on the west by the Tigray Region, on the north by Eritrea, and on the east and south by Berhale. Detailed information is not available for the settlements in this woreda.
Document 10: Republic of the Congo: Following the revision of the French constitution that established the Fifth Republic in 1958, the AEF dissolved into its constituent parts, each of which became an autonomous colony within the French Community. During these reforms, Middle Congo became known as the Republic of the Congo in 1958 and published its first constitution in 1959. Antagonism between the pro-Opangault Mbochis and the pro-Youlou Balalis resulted in a series of riots in Brazzaville in February 1959, which the French Army subdued.
Document 11: Somalis: British Somaliland became independent on 26 June 1960 as the State of Somaliland, and the Trust Territory of Somalia (the former Italian Somaliland) followed suit five days later. On 1 July 1960, the two territories united to form the Somali Republic, albeit within boundaries drawn up by Italy and Britain. A government was formed by Abdullahi Issa Mohamud and Muhammad Haji Ibrahim Egal other members of the trusteeship and protectorate governments, with Haji Bashir Ismail Yusuf as President of the Somali National Assembly, Aden Abdullah Osman Daar as the President of the Somali Republic and Abdirashid Ali Shermarke as Prime Minister (later to become President from 1967 to 1969). On 20 July 1961 and through a popular referendum, the people of Somalia ratified a new constitution, which was first drafted in 1960. In 1967, Muhammad Haji Ibrahim Egal became Prime Minister, a position to which he was appointed by Shermarke. Egal would later become the President of the autonomous Somaliland region in northwestern Somalia.

Document 13: Israel: The Jordan River runs along the Jordan Rift Valley, from Mount Hermon through the Hulah Valley and the Sea of Galilee to the Dead Sea, the lowest point on the surface of the Earth. Further south is the Arabah, ending with the Gulf of Eilat, part of the Red Sea. Unique to Israel and the Sinai Peninsula are makhteshim, or erosion cirques. The largest makhtesh in the world is Ramon Crater in the Negev, which measures 40 by 8 kilometers (25 by 5 mi). A report on the environmental status of the Mediterranean basin states that Israel has the largest number of plant species per square meter of all the countries in the basin.
Document 14: Lake Vanda: Lake Vanda is a lake in Wright Valley, Victoria Land, Ross Dependency, Antarctica. The lake is 5 km long and has a maximum depth of 69 m. On its shore, New Zealand maintained Vanda Station from 1968 to 1995. Lake Vanda is a hypersaline lake with a salinity more than ten times that of seawater, more than the salinity of the Dead Sea, and perhaps even more than of Lake Assal (Djibouti), which is the world's most saline lake outside of Antarctica. Lake Vanda is also meromictic, which means that the deeper waters of the lake don't mix with the shallower waters. There are three distinct layers of water ranging in temperature from on the bottom to the middle layer of and the upper layer ranges from . It is only one of the many saline lakes in the ice-free valleys of the Transantarctic Mountains. The longest river of Antarctica, Onyx River, flows West, inland, into Lake Vanda. There is a meteorological station at the mouth of the river.
Document 15: Lake Assal (Djibouti): Lake Assal ( , literally 'honey lake') is a crater lake in central-western Djibouti. It is located at the western end of Gulf of Tadjoura in the Tadjoura Region, touching Dikhil Region, at the top of the Great Rift Valley, some west of Djibouti city. Lake Assal is a saline lake which lies below sea level in the Afar Triangle, making it the lowest point on land in Africa and the third-lowest point on Earth after the Sea of Galilee and the Dead Sea. No outflow occurs from the lake, and due to high evaporation, the salinity level of its waters is 10 times that of the sea, making it the third most saline body of water in the world behind Don Juan Pond and Gaet'ale Pond. Lake Assal is the world's largest salt reserve, which is exploited under four concessions awarded in 2002 at the southeast end of the lake; the major share of production (nearly 80%) is held by Société d’Exploitation du Lac and Société d’Exploitation du Salt Investment S.A de Djibouti. It is situated approximately west of the nation's capital Djibouti City.
