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: D

Correct answer: 14 nick 37 height flower cost 42 57

The illustration places the smallest remaining number, then the alphabetically last remaining word, alternately from the left. Here that order is 14, nick, 37, height, 42, flower. Step 1 brings 14 to the front, giving 14 nick flower 37 cost height 42 57. The next element, nick, is already in position two, so no step is printed for it - the machine only records a step when something actually moves. Step 2 therefore brings 37 to position three, and step 3 brings height to position four: 14 nick 37 height flower cost 42 57.

Answer: C

Correct answer: 17 victory 19 town 37 58 store like

The order of placement is smallest number, then alphabetically last word, alternately: 17, victory, 19, town, 37, store. The line given as step 2 already has 17 and victory in place, and 19 happens to be sitting in position three already, so the machine prints no step for it. The next move that changes anything is town to position four, which gives 17 victory 19 town 37 58 store like.

Answer: A

Correct answer: Three

The placement order for this line is 36, window, 45, ultra, 86, queen, with 96 and book left over. Step 3 has 36, window and 45 in place, so three moves remain: ultra to position four, then 86 to position five, then queen to position six. After that only 96 and book are left and the arrangement is complete, so three more steps are needed.
