Step IV reads 19 37 49 ace hot sun best ice cut 67 77 83: the three smallest numbers and the alphabetically first word have been placed at the left, the three largest numbers at the right. Counting from the right, 83 is first, 77 second, 67 third, cut fourth, ice fifth, best sixth and sun seventh.

Answer: B

Correct answer: 19 37 49 ace best cut hot ice sun 67 77 83

The machine finishes with the numbers split around the words: the smaller half in ascending order at the left, the words alphabetically in the middle, and the larger half in ascending order at the right. Here that gives 19, 37 and 49 first, then ace, best, cut, hot, ice, sun, and finally 67, 77 and 83. The illustration ends the same way, with 15, 31, 46 then the six words then 52, 73, 91.

Answer: D

Correct answer: 19 67 hot sun best ice 49 ace 77 cut 37 83

Each of the early steps moves two numbers at once: the smallest remaining to the left end and the largest remaining to the right end, with everything else keeping its order. From the input, 19 goes to the front and 83 to the back, leaving 67 hot sun best ice 49 ace 77 cut 37 untouched between them.

Answer: C

Correct answer: V

Following the input through: Step I places 19 and 83, Step II places 37 and 77, and Step III places 49 and 67, which exhausts the numbers and gives 19 37 49 hot sun best ice ace cut 67 77 83. The words are then placed alphabetically one per step - ace at Step IV and best at Step V, giving exactly 19 37 49 ace best hot sun ice cut 67 77 83.

Answer: D

Correct answer: VII

Three steps place the six numbers, two at a time. The words then go in alphabetically at one per step: ace at IV, best at V, cut at VI. At that point the line reads 19 37 49 ace best cut hot sun ice 67 77 83, and “hot” is already in its correct place, so the machine passes over it and Step VII moves “ice” ahead of “sun”. That completes the arrangement, exactly as the illustration stopped early once its remaining words happened to be in order.
