Read the passage from Ronald Reagan's "Tear Down This Wall" speech. Where four decades ago there was rubble, today in West Berlin there is the greatest industrial output of any city in Germany—busy office blocks, fine homes and apartments, proud avenues, and the spreading lawns of park land. Where a city's culture seemed to have been destroyed, today there are two great universities, orchestras and an opera, countless theaters, and museums. Where there was want, today there's abundance. . . . From devastation, from utter ruin, you Berliners have, in freedom, rebuilt a city that once again ranks as one of the greatest on earth. . . .

In the 1950s, Khrushchev predicted: "We will bury you." But in the West today, we see a free world that has achieved a level of prosperity and well-being unprecedented in all human history. In the Communist world, we see failure, technological backwardness, declining standards of health, even want of the most basic kind—too little food. Even today, the Soviet Union still cannot feed itself. After these four decades, then, there stands before the entire world one great and inescapable conclusion: Freedom leads to prosperity. Freedom replaces the ancient hatreds among the nations with comity and peace. Freedom is the victor.

Which statement best describes Reagan’s main message for his audience in this excerpt?

The Berlin Wall is a reminder of the past and of the war.
The United States is more powerful than the Soviet Union.
Democracy leads to greater prosperity than communism does.
Berlin is a thriving city that can boast of many accomplishments.
