Answer:
one example of when he tried to strengthen or weaken the attitudes, beliefs or values of his audience is
"Yet, it is here in Berlin where the wall emerges most clearly; here, cutting across your city, where the news photo and the television screen have imprinted this brutal division of a continent upon the mind of the world. Standing before the Brandenburg Gate, every man is a German separated from his fellow men. Every man is a Berliner, forced to look upon a scar."
one example of where he attempts to change the attitudes, beliefs or values of his audience is
"President Von Weizsäcker has said, "The German question is open as long as the Brandenburg Gate is closed." Well today -- today I say: As long as this gate is closed, as long as this scar of a wall is permitted to stand, it is not the German question alone that remains open, but the question of freedom for all mankind."
one example of where President Regan attempts to motivate his audience to action is
"There is one sign the Soviets can make that would be unmistakable, that would advance dramatically the cause of freedom and peace. General Secretary Gorbachev, if you seek peace, if you seek prosperity for the Soviet Union and Eastern Europe, if you seek liberalization: Come here to this gate. Mr. Gorbachev, open this gate. Mr. Gorbachev -- Mr. Gorbachev, tear down this wall!"
