Which of the events in the “causes” column do you think had the strongest impact on enslaved african americans? explain why ?

I would honestly say that the "effects" are a bit hard to understand, however, the best choice I could give you is the very first one. Fugitive slave act. I say this because this is one of the only ones that affected a larger spectrum of African Americans, and not limited down to one state or Person.

so they can differentiate themselves from others as they saw themselves as the superior race. the star was basically a symbol that meant you are a less of a person than i am because of my race. the star was also degrading for those who had to wear it because they were aware of this and the nazis used the notion to make them feel less like a person.
