According to the material, Neil Armstrong was the...

• A. Was the first man to walk on the Moon
• B. Was the first American to orbit the Earth
• C. First person to reach the Moon
• D. First human in space

Answer: (A)

Understanding who achieved the first Moon walk and how it differs from other space milestones is key here. Neil Armstrong holds the distinction of being the first person to walk on the Moon, which happened during the Apollo 11 mission in 1969. This is a specific achievement: stepping onto the lunar surface and moving around there, not merely reaching or orbiting the Moon. Other firsts are different roles in space history—John Glenn was the first American to orbit the Earth, Yuri Gagarin was the first human in space, and neither of those events involved setting foot on the Moon. So the statement that Armstrong was the first man to walk on the Moon best captures his iconic accomplishment.
