Explanation:

1. First, identify the correct chronological order of the events:

• The Russians successfully launched a satellite (Sputnik) into orbit in 1957 (but the problem is about the 1960s, and this event is a precursor to 1960s space tech).
• The NASA satellite Telstar 1 transmitted a signal between Europe and the United States in 1962.
• American scientists successfully tested the first working laser in 1960.
• American astronauts walked on the moon in 1969.

1. Now, order them based on the timeline:

• First: The Russians successfully launched a satellite into orbit (1957, but relevant to 1960s space race context).
• Second: American scientists successfully tested the first working laser (1960).
• Third: The NASA satellite Telstar 1 transmitted a signal between Europe and the United States (1962).
• Fourth: American astronauts walked on the moon (1969).

Answer:

1. The Russians successfully launched a satellite into orbit
2. American scientists successfully tested the first working laser
3. The NASA satellite Telstar 1 transmitted a signal between Europe and the United States
4. American astronauts walked on the moon
