Answer:
Religious persecution
Explanation:
I'm kinda in between this answer and "political instability," but I chose "Religious persecution" because if you think about what was going on in Europe during the late 19th and early 20th centuries, you will realize that Nazi Germany was forming. Nazis persecuted those of Jewish descent, which was a major reason why masses of Jews traveled to the United States during this time.
I must mention, however, that Nazis persecuted those of Jewish descent regardless of whether they actually practiced Judaism or not. In other words, Judaism did not necessarily have to be your religion to be persecuted by the Nazis.
Keeping that in mind, you might want to double-check this and make sure that the correct answer isn't "political instability."
I know that I wasn't really able to give you a solid answer, but I still hope that this helps you out in some way!
Please give me Brainliest!
Cheers!
