Step-by-step explanation:
A Jewish supporter of assimilation most likely would have urged Jews to remain in Europe.
Assimilation refers to the process of blending into the larger society and culture. In the context of this question, a Jewish supporter of assimilation would encourage Jews to integrate and become part of the European society rather than seeking a separate homeland or migrating to Palestine. By remaining in Europe, they would aim to overcome stereotypes and discrimination, and contribute to the social and economic fabric of their adopted countries.
