Answer:
“Conrad’s picture of the peoples of the Congo seems grossly inadequate even at the height of their subjection to the ravages of King Leopold’s International Association for the Civilization of Central Africa.”
Step-by-step explanation:
A counterclaim is a statement used to contest a claim shown earlier, with arguments showing that the claim is incorrect.
In the case shown in the question above, we can see that Achebe has a refutation, a counterclaim, the claim that Conrad knew Africa because he had traveled there in 1890, stating that Conrad's account of the peoples of the Congo in Africa is extremely incorrect, which shows that her trip to the continent in 1890 did not allow him to absorb any concrete and correct knowledge about Africa and its inhabitants.
