Final answer:
The question lacks context to definitively answer which language was most spoken in Levi's camp, but in Holocaust camps, languages like German, Yiddish, Polish, and Hungarian were common.
Step-by-step explanation:
The question does not provide enough context to accurately determine which language was most spoken in Levi's camp.
This might refer to Primo Levi, an Italian Jewish writer and Holocaust survivor, but without additional context regarding the specific camp or historical setting, it is not possible to assert with certainty the most spoken language there.
In various concentration camps during World War II, multiple languages would have been spoken, with languages like German, Yiddish, Polish, Hungarian, and many others being common among the diverse prisoner population.
