Question

1. the 13th amendment to the u.s. constitution greatly expanded civil rights for african americans by ending which of the following?

slavery
boycotts
segregation
discrimination

Explanation:

The 13th Amendment to the U.S. Constitution abolished slavery and involuntary servitude (except as punishment for a crime). Boycotts are a form of protest, segregation was addressed by later civil rights efforts (like the 14th and 15th Amendments and later laws), and discrimination is a broader issue not ended by the 13th Amendment. So the 13th Amendment ended slavery.

Answer:

The correct option is the one with "slavery" (the first option in the list of choices).
