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.

Answer: C

Correct answer: uncut orach ink eye ant star race gam fun cost

This machine works from both ends at once. Words beginning with a vowel go to the front in reverse alphabetical order - uncut, orach, ink, eye, ant - and words beginning with a consonant go to the back in alphabetical order, the alphabetically first taking the very last place: cost, then fun, Game, race, star working inwards. The finished line is therefore uncut orach ink eye ant followed by star race Game fun cost.

Answer: D

Correct answer: There will be no such step as the input gets.

Each step of this machine makes two moves, one at the front and one at the back, so ten words are arranged in five steps: uncut with cost, orach with fun, ink with Game, eye with race, ant with star. The arrangement is complete at step V, and there is no step VII to ask about.
