Yes that is true. The MPLA was able to gain control blah blah blah. Oi. I hate H&G.
The answer is A ( I have to add more but give me a thanks
Before Spanish colonization, Mexico has established its own class structure among the population. However, after colonization, the class structure changed drastically. The Spanish elites imposed a caste system with different levels of biological mixtures between different ethnic groups living in Mexico which decided one's status in society. Those who were biologically more Spanish enjoy a better standard of life than those from Indigenous or African lineage. The strict hierarchy caused discontent among the people which led to civil unrest and an inevitable revolution.
I think its A. I'm not entirely sure but it does seem most logical.
<u>Anyways a big reason that these powers are limited is to keep society in a stable place. Tyranny brought onto any civilization over the years has led to its downfall. This balance helps keep both the government and its people under equal terms. </u>
Its not B. because this would allow tyrant rulers to keep their position putting everyone else at a disadvantage to please themselves. This simply doesn't make sense if you were to limit the government.
C. isn't a possibility either because each government only governs over said region.
D. can also be justified under my response to B. since it has the same meaning yet is worded differently/ or relates to more modern leaders I suppose.
Anyways, I hope I was helpful and good luck :D
