Final answer:
The conquest of Africa by Europeans was facilitated by quinine, mechanized vehicles, advanced weaponry, the Atlantic slave trade, and the Berlin Conference.
Step-by-step explanation:
The conquest of Africa by Europeans was facilitated by several inventions and developments. The discovery of quinine helped Europeans treat and prevent malaria, which had previously limited their ability to venture into the interior of Africa. Additionally, the development of mechanized vehicles and advanced weaponry gave Europeans an advantage over local populations. These technological advancements, along with the Atlantic slave trade and the Berlin Conference, ultimately contributed to Europe's conquest of Africa.
