What limits do anthropological studies of modern societies have as historical sources ?

Anthropology is the science which studies the humans in society, also, the relations between this society and the environment. Modern anthropology is a discipline inside the anthropology. It tries to explain man through his social and cultural environment.

When anthropology as a discipline is applied to modern societies there is a factor that generates a problem, time. We don´t have enough historical resources to size the real impact of situations, for example, climatic problems.  

In ancient civilizations studies, we employ a diachronic method so as we can measure the evolution and progress of cultural and natural events. In the case we study of modern civilizations, the consequences of different situations aren't quantifiable, so the conclusions we can get are partial.

the correct answer is individualism and exchange. at this stage, children begin to question the rules, because they can see that there is more than one side to them. different individuals have different viewpoints. they won't be able to reach this stage because of ignorance, a lack of ethics or personal biases. that is because people with that characteristiscs are not able to distinguish what is good or what is bad and they can't pursue their individual interests.

the correct answer is option c. elenita versus "early puerto rican decor" is the best example, out of all the options, of a cultural conflict. a cultural conflict is defined as what happens when different cultures, that have different values and believes, clash. elenita not liking or accepting the puerto rican style of decoration, would represent that she does not identify herself with the puerto rican culture, therefore does not want to have decorations influenced by that culture.
