Final answer:
Children and the elderly were often the first to die at concentration camps during the Holocaust, as they were sent to gas chambers upon arrival due to their inability to work. Other groups targeted included Jewish people, Romani, and various political prisoners. The extreme conditions, forced labor, and medical experiments claimed countless lives.
Step-by-step explanation:
During the Holocaust, the types of people who were usually the first to die at a concentration camp included children, the elderly, and those deemed unfit for work. According to historical accounts, these individuals were often sent directly to the gas chambers upon arrival at death camps such as Auschwitz, since they were not considered capable of performing forced labor. Those who were not killed immediately faced harsh conditions, including forced labor, starvation, disease, and medical experiments.
Groups targeted for extermination also included Jewish people, Romani, gay individuals, Jehovah's Witnesses, and political dissidents, among others. However, children and the elderly were particularly vulnerable and often among the first victims due to their inability to withstand the brutal conditions of the camps or to contribute to the Nazi forced labor efforts.
