Final answer:
The cartoon likely reflects the sentiment that too many Jewish immigrants were entering the United States, indicative of the broader discrimination and hostility they faced during the early 1900s. The correct option is 3.
Step-by-step explanation:
The cartoon about American attitudes toward Jewish immigrants in the early 1900s suggests that Americans felt that too many Jewish immigrants were coming to the United States. This interpretation reflects broader social sentiments of the period, where widespread prejudices against newcomers, particularly those from Southern and Eastern Europe, such as the Jews, were common.
The anti-Semitic stereotypes, coupled with cultural differences and religious practices, made Jewish immigrants targets for discrimination and hostility. Unlike other immigrant groups who eventually assimilated into American society, Jewish immigrants encountered persistent barriers, and these attitudes extended well into the mid-20th century, affecting immigration policies and leaving Jewish refugees in peril during World War II.
