Final answer:
David Livingstone and Henry Stanley both sought to map Africa, Livingstone as a mission-driven abolitionist, while Stanley was an opportunistic journalist. They differed also in nationality, Livingstone being British and Stanley American.
Step-by-step explanation:
David Livingstone and Henry Stanley were similar in their attitudes towards Africa in that they both were European explorers motivated by a desire to venture into and map the African continent. However, their reasons and approaches diverged. Livingstone was primarily a missionary with humanitarian inclinations, advocating against the slave trade, whereas Stanley was a journalist and explorer with a more opportunistic outlook, focusing on the exploration and reporting aspects. Geographically, Livingstone was British, and Stanley was American, which shaped their differing perspectives based on their national backgrounds and the imperialistic aims of their respective countries during the age of colonization.
