Developing nations tend to be more heavily affected by pandemics than developed ones because developing nations lack the resources to control the spread of disease - B. This often is the case and has also been the reason why many deadly viruses have been spread out in Africa for example or some parts of Asia in comparison to the US.
The correct answer is "C. all of history has been a struggle between classes of people."
Karl Marx was a German economist and socialist revolutionary who developed the theory of Marxism, which states that societies have developed a long time through <em>class struggle</em>. He attributes this to <em>capitalism</em>, where the ruling classes, which control the means of production enter in conflict with the working classes, also known as <em>"the proletariat"</em>. This constant struggle would eventually lead to the fall of capitalism and the rise of a new system called <em>socialism</em>.
You answer would be A or the first option because if they got the same results then it is most likely that they are both correct
