In which year did humans first step on the Moon?

Correct answer: 1969

The direct answer is D, 1969. Humans first landed on the Moon during NASA’s Apollo 11 mission. On 20 July 1969, astronaut Neil Armstrong stepped onto the lunar surface, followed shortly by Buzz Aldrin; Michael Collins remained in lunar orbit. Step by step: identify the first crewed Moon landing as Apollo 11; remember its year, 1969; select option D. Option A, 1950, was too early because no human Moon landing had occurred then. Option B, 1960, was also before the Apollo 11 landing; space exploration was still developing. Option C, 1975, was after the first landing and therefore cannot be correct. Option D is correct because it gives the year of humanity’s first lunar landing. Exam cue: Apollo 11 = first Moon landing = 1969. Do not confuse the year with later Apollo missions.
