Question

which of the following directly violated the intent of the fifteenth amendment to the constitution?
poll taxes
first-class railroad tickets
racially segregated hospitals
racially segregated schools

Explanation:

The Fifteenth Amendment prohibits denying the right to vote based on race, color, or previous servitude. Poll taxes were used to disenfranchise Black voters (and others), violating the amendment's intent to ensure voting rights regardless of race. First - class railroad tickets, racially segregated hospitals, and racially segregated schools relate to segregation in other areas (transportation, healthcare, education) not directly to voting rights which the Fifteenth Amendment focuses on.

Answer:

A. poll taxes
