Answer and Explanation:
With the reading of the text above, we can conclude that:
By proving that the Zambezi was navigable, Livingstone hoped to establish a different path and exploration of the African continent. Livingstone wanted to establish a "highway into the interior" showing that Africa was exploitable through its commercial potential and that Africans could be seen as workers and traders.
He felt that slavery was an inhumane activity and torture of living beings, for that reason, it was necessary that it be eliminated from all parts of the world and that Africans be seen as dignified and free human beings.
From this information, I can tell that he is against slavery and wants to prevent it from happening. In addition, we can see that he wants the African continent to be valued and strengthened, making connections with other countries in a commercial and fair manner.
