If light didn't travel in a straight line, ____?

Question

a) objects would be located somewhere different from where they appear

b) we would never receive sunlight

c) we would not be able to see at all

d) life on earth would not be possible

e) car headlights would still work

Answer 1

Most likely "A". The question is really speculation, because there's a good chance that if light didn't travel in a straight line our vision would have developed differently than it did.

There is some evidence, by the way, that over great distances in space light does indeed curve.
