If these three pictures were from the same story, which one do you think might come first Why
I think Picture B might come first because the man in Picture C is running, and in Picture B, we can see an alien is running after him.
I don’t agree. I think Picture A must come first. In Picture A, we can see a UFO landing. The UFO has to land before the alien can come out and run after the man.
