Question 1 Part A:
The argument that Kennedy makes in his "Ich bin ein Berliner" speech is:
Many Germans have suffered under communism.
Question 2 Part B:
The answer choice that presents the most logical reasoning in support of the argument identified in Part A is:
"... one German out of four is denied the elementary right of free men, and that is to make a free choice."
This statement directly highlights the suffering of Germans under communism by emphasizing the lack of freedom and choice experienced by a significant portion of the population.
