B. discourage African Americans from voting.
Poll taxes means you have to pay a tax before allowed to vote. That's a way of preventing poor persons (like blacks in the South) from voting.
In addition to poll taxes, other measures were also used to block blacks from participating in the voting process. For instance, literacy tests would require persons to pass certain standards of reading and writing in order to qualify for voting. These tests were aimed at blacks, who had not had access to the same education as whites.
The Soviet Union intended to block all routes in and out of West Berlin for two reasons. They wanted to stop all people from escaping, and they also wanted to stop other countries, such as the US, from giving the West Berliners supplies.
It was the "nativists" who believed that only long-ago immigrants from Western Europe could become real Americans, since they believed these immigrants were "natives" to the land.
