The image shown below shows that I was incorrect when I chose the first answer, A: All Texas citizens were allowed to vote in the Democratic primary, and shows the feedback I was given, telling me that the correct answer is D: The Texas legislature was required to redraw the state's voting districts.
If this was incorrect, please, don't refrain to tell me. Thank you.
