premise: In 1962, Armstrong was transferred to astronaut status. He served as command pilot for the Gemini 8 mission, launched March 16, 1966, and along with David Scott, performed the first successful docking of two vehicles in space by mating his Gemini 8 with an uninhabited Agena rocket.
hypothesis: The Gemini 8 mission was launched in the first month of 1966.
reason: March is not the first month in 1966, or any year. It's difficult because the system might not understand how the months are ordered.
