Question

long before humans made electronic satellites to orbit the earth for communications, humans had been observing the moon. through centuries of thought and experimentation, scientists realized that the invisible force of gravity was holding the moon and other matter in orbit around earth. then in the twentieth century, humans began putting their own satellites in orbit. how do the discovery of gravity and the invention of electronic satellites most likely relate to the processes of scientific investigation and technological design?
engineers used the process of technological design to discover how gravity holds matter in orbit, and then scientists investigated satellites in nature.
scientific investigations discovered that gravity holds objects in orbit, and then technological designers used the discovery to develop electronic satellites.
since scientists were curious about gravity, they used the process of scientific investigation to build the first object that would orbit earth.
technological designers invented the electronic satellite, and then scientific investigators conducted research to learn how and why it orbited around earth.

Explanation:

Scientific investigation involves discovering natural phenomena (e.g., gravity holding objects in orbit). Technological design applies such discoveries to create innovations (e.g., electronic satellites). The passage states centuries of scientific thought/experimentation revealed gravity's role, followed by 20th-century satellite development, aligning with this sequence.

Answer:

B. Scientific investigations discovered that gravity holds objects in orbit, and then technological designers used the discovery to develop electronic satellites.
