Explanation:

To solve this problem, we need to identify the pattern used for rearranging the input in each step, and then apply the same pattern to the new set of input.

- In each step of the rearrangement process, words and numbers are rearranged alternately. Specifically, words are organized alphabetically from right to left, while numbers are sorted from highest to lowest in descending order and placed leftmost.

- By the end of each step, a word or number reaches its correct position in the sequence. Progress continues until all elements are sorted.

Given the input "81 Reverse 68 Dance 35 57 Length Yielding 93 42 Progress Easily", we apply the same rule as in the illustration to reach Step III.

- Step I: Reverse 81 68 Dance 35 57 Length Yielding 93 42 Progress 35 Easily

- Step II: 68 Reverse 81 Dance Length Yielding 93 42 Progress 35 Easily 57

- Step III: Length 68 Reverse 81 Dance Yielding 93 42 Progress 35 Easily 57

In Step III, the numbers on the left are "68" and "81". Their sum is:

- $68 + 81 = 149$

The sum of the first two numbers from the left end is 149.

- Options:

- 1. 110

- 2. 149

- 3. 131
