Answer:
Explanation:
The geography of North Africa has been reasonably well known among Europeans since classical antiquity in Greco-Roman geography. Northwest Africa (the Maghreb) was known as either Libya or Africa, while Egypt was considered part of Asia.
European exploration of Sub-Saharan Africa begins with the Age of Discovery in the 15th century, pioneered by Portugal under Henry the Navigator. The Cape of Good Hope was first reached by Bartolomeu Dias on 12 March 1488, opening the important sea route to India and the Far East, but European exploration of Africa itself remained very limited during the 16th and 17th centuries. The European powers were content to establish trading posts along the coast while they were actively exploring and colonizing the New World. Exploration of the interior of Africa was thus mostly left to the Arab slave traders, who in tandem with the Muslim conquest of Sudan established far-reaching networks and supported the economy of a number of Sahelian kingdoms during the 15th to 18th centuries.
At the beginning of the 19th century, European knowledge of the geography of the interior of Sub-Saharan Africa was still rather limited. Expeditions exploring Southern Africa were made during the 1830s and 1840s, so that around the midpoint of the 19th century and the beginning of the colonial Scramble for Africa, the unexplored parts were now limited to what would turn out to be the Congo Basin and the African Great Lakes. This "Heart of Africa" remained one of the last remaining "blank spots" on world maps of the later 19th century (alongside the Arctic, Antarctic and the interior of the Amazon basin). It was left for 19th-century European explorers, including those searching for the famed sources of the Nile, notably John Hanning Speke, Sir Richard Burton, David Livingstone and Henry Morton Stanley, to complete the exploration of Africa by the 1870s. After this, the general geography of Africa was known, but it was left to further expeditions during the 1880s onward, notably, those led by Oskar Lenz, to flesh more detail such as the continent's geological makeup
One by one, the Classic cities in the southern lowlands were abandoned, and by A.D. 900, Maya civilization in that region had collapsed. The reason for this mysterious decline is unknown, though scholars have developed several competing theories. which is Maya had exhausted the environment around them to the point that it could no longer sustain a very large population. <span>Other Maya scholars argue that constant warfare among competing city-states led the complicated military, family (by marriage) and trade alliances between them to break down, along with the traditional system of dynastic power. As the stature of the holy lords diminished, their complex traditions of rituals and ceremonies dissolved into chaos. Finally, some catastrophic environmental change–like an extremely long, intense period of drought–may have wiped out the Classic Maya civilization. Drought would have hit cities like Tikal–where rainwater was necessary for drinking as well as for crop irrigation–especially hard</span>

(3) Africans eliminated warriors in rival tribes by selling or trading captured prisoners to slave traders.
Answer:
The cause of world war one
Explanation:
World war one was caused by the death of Archduke Franz Ferdinand. He was murdered by a gang called the Black hand gang. The leader of this notorious gang was Dragutin Dimitrijevic. He was a Serbian who wanted freedom for his country. What he didn't know was that Franz Ferdinand was actually trying to negotiate with Serbia. He was shot by Gavrilo Princip (one of the members of the Black Hand gang. Princip was 19) Ferdinand and his wife Sophie were killed on 28th June 1914. Sophie was pregnant at that time so their child (soon to be born) didn't survive. This caused anger but there was another series of events which actually caused the war. Through her alliance with Britain, Japan declares war on Germany and attacks the German colony of Tsingtau in China. World War one officially started on 28th July 1914.
