Answer:
Constitution of 1890
Explanation:
The constitution of 1890 put literacy test as a requirement for people before they were allowed to cast their votes during the election.
At that time, the constitution was designed to reduce the power of minorities vote in the government.
A lot of black citizens during that time period did not have access to education due to their poor economic condition. As a result, black communities had a high illiteracy rate compared to white communities. This made a lot of black people unable to cast of their votes and choose their representatives within the government.
I think the Maths is more important .
The Constitution was written in 1787
