Question

what was the link between the launch of sputnik i and the national defense educational act?
the national defense education act was created in response to the launch of sputnik i.
the development of sputnik i came about because of information generated by the national defense education act.
the launch of sputnik i meant the us no longer needed the funds provided by the national defense education act.
the national defense education act created the funds necessary to develop and launch sputnik i.

Explanation:

The launch of Sputnik I by the Soviet Union in 1957 was a significant event during the Cold War. It made the US government realize that it needed to improve its science, technology, engineering, and mathematics (STEM) education to keep up with the Soviet Union in the space and technological race. As a result, the National Defense Educational Act was passed in 1958. It provided funds for education, especially in STEM - related fields.
The other options are incorrect. Sputnik I was a Soviet achievement, so options related to US - based funding for its development (like the last option) are wrong. Also, the National Defense Education Act was a response to Sputnik, not the other way around (so the second option is wrong), and the US did not stop needing educational funds after Sputnik (so the third option is wrong).

Answer:

The National Defense Education Act was created in response to the launch of Sputnik I.
