4. We use the electromagnetic spectrum to study space by viewing planetary images and satellite photographs. If we were only able to use visible light
wavelengths to study space how would that affect our current knowledge of
space?

To me we wouldn't know as much as we do. There is so much they don't want us to know about space. Just watch the moon at night and you can get a better answer.

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
