1 is "A" because it most strongly represents basic imperialism, and could be used as an example of social darwinism. I think 2 is "C" because nothing else really makes sense. "Encomienda" in Spanish is "Parcel" and "Pinturas de Castas" is "Paintings of Breeds" and since this passage mainly consists of imperialistic men enslaving the people of another land, it fits best with "C". Hope it helps!
