Answer:
questions showing the ability to read and write
Step-by-step explanation:
The questions potential voters have to answer on Louisiana literacy tests in 1964 were "questions showing the ability to read and write"
This is evident in that for example some of the questions are:
Draw a circle around the number or letter of this sentence.
Draw a circle under the last word in the line.
Cross out the longest word in this line.
Going by these examples shows that the questions do not relate to the constitution, school integration, NACCP nor government, but just the ability to read and write.
