Question

Which of the following was a NASA program that served as a bridge between human space flight and the moon

landing?
Mercury
O Gemini
O Apollo
O Sputnik

Answer 1

I don’t understand what you mean by a “bridge”, but I can briefly explain what all of these answer choices mean.

Mercury was the first mission that got Americans into space
Gemini worked towards the moon
Apollo was the first men on the moon
Sputnik had nothing to do with NASA, this answer choice is wrong

If I had to guess I’d say it’s Apollo

Hope this helps
