Which event first achieved humans landing on the Moon?

• A. Sputnik 1 launch
• B. Apollo 11 Moon landing
• C. Challenger disaster
• D. Mercury-Redstone 3 flight

Answer: (B)

The main idea being tested is identifying the first time humans landed on the Moon. Apollo 11 accomplished that historic feat in 1969, with Neil Armstrong and Buzz Aldrin becoming the first humans to walk on the lunar surface while Michael Collins orbited above. Earlier, Sputnik 1 in 1957 was the first artificial satellite but never reached the Moon. Mercury-Redstone 3, the 1961 flight that carried Alan Shepard, was a suborbital test and did not reach the Moon. The Challenger disaster in 1986 involved a space shuttle launch failure and is unrelated to lunar landings. Therefore, Apollo 11 is the correct event because it marks the first crewed Moon landing.
