Answer: D

Correct answer: Cannot be determined

The same irreversibility applies whether you are asked for the input or for an earlier step. Each move destroys the record of where the moved element used to sit, so working backwards from step III to step I is no more possible than working back to the input - several different step I lines lead to the same step III.

Answer: D

Correct answer: Cannot be Determined

Every step of these machines moves one element to a fixed position and lets the rest close up behind it, so the original positions of the elements still waiting are lost as soon as the first move is made. The process runs one way only: from a later line you can say what will follow but never what came before, because many different inputs produce the same intermediate line. That is why the answer to any “what was the input” question of this kind is that it cannot be determined.
