Brief Explanations:

The meetings between Reagan (U.S. President) and Gorbachev (Soviet leader) were part of the end - of - Cold - War diplomacy. The Cold War was characterized by high - tension, often hostile relations between the U.S. and the Soviet Union. Diplomatic cooperation was a significant shift from the previous status - quo of proxy wars (e.g., in Afghanistan, Angola) and an arms race. Military strategies were not the sole focus (as the second option claims), and space exploration programs (third option) were not the main aim. The key was reducing Cold - War tensions through diplomatic means.

Answer:

They marked a shift towards diplomatic cooperation.
