Answer:
He wants the Soviet Union to demonstrate support for freedom in Berlin is the correct answer.
Explanation:
The passage is the following:
"We hear much from Moscow about a new policy of reform and openness. Some political prisoners have been released. Certain foreign news broadcasts are no longer being jammed. Some economic enterprises have been permitted to operate with greater freedom from state control.
Are these the beginnings of profound changes in the Soviet state? Or are they token gestures, intended to raise false hopes in the West, or to strengthen the Soviet system without changing it? We welcome change and openness; for we believe that freedom and security go together, that the advance of human liberty can only strengthen the cause of world peace.
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, tear down this wall!"
–“Tear Down This Wall” speech,
Ronald Reagan
This speech was delivered in West Berlin on June 12, 1987; its main intention was to challenge Mikhail Gorbachev, the General Secretary of the Communist Party to open the Berlin Wall. Even though the speech did not receive a lot of attention, it became popular after the Wall fell in 1989. Due to this, the correct answer is the last option.
