Archaeology is the study of the human past through its material remains. Artifacts, faunal remains, and human altered landscapes are evidence of the cultural and material lives of past societies. Archaeologists examine these material remains in order to deduce patterns of past human behavior and cultural practices. Ethnoarchaeology is a type of archaeology that studies the practices and material remains of living human groups in order to gain a better understanding of the evidence left behind by past human groups, who are presumed to have lived in similar ways.
What do Ethnoarchaeologists gain a better understanding of by studying living human groups?
past human groups

Switzerland's trade was blockaded by both the Allies and by the Axis. Economic cooperation and extension of credit to the Third Reich varied according to the perceived likelihood of invasion and the availability of other trading partners. Concessions reached a peak after a crucial rail link through Vichy France was severed in 1942, leaving Switzerland completely surrounded by the Axis. Over the course of the war, Switzerland interned over 300,000 refugees and the International Red Cross, based in Geneva, played an important part during the conflict. Strict immigration and asylum policies as well as the financial relationships with Nazi Germany raised controversy, but not until the end of the 20th century.
When did the financial relationship Switzerland had with Nazi Germany begin to raise controversy?
end of the 20th century
