A word-and-number arrangement machine rearranges a given input following a specific rule in each step. The rule involves moving the alphabetically smallest word to the leftmost side and the numerically largest number to the rightmost side in each step. The process continues until all words are arranged in alphabetical order at the left end, and all numbers in descending order at the right end.
Based on the pattern, answer the questions that follow the given input.
Input: Shine 34 12 Gravity 91 20 Echo Bounce Mirror 73 50
Question: Which word is placed at the 3rd position from the left in Step IV? ​​

Logic/Rule: In each step, put the alphabetically smallest word to the left. Put the largest number to the right.

Shine 34 12 Gravity 91 20 Echo Bounce Mirror 73 50

Smallest word alphabetically = Bounce

Largest number = 91

After Step I:
Bounce Shine 34 12 Gravity 20 Echo Mirror 73 50 91

Remaining words: Shine, Gravity, Echo, Mirror → smallest = Echo

Remaining numbers: 34, 12, 20, 73, 50 → largest = 73

After Step II:
Bounce Echo Shine 34 12 Gravity 20 Mirror 50 73 91

Remaining words: Shine, Gravity, Mirror → smallest = Gravity

Remaining numbers: 34, 12, 20, 50 → largest = 50

After Step III:
Bounce Echo Gravity Shine 34 12 20 Mirror 50 73 91

Remaining words: Shine, Mirror → smallest = Mirror

Remaining numbers: 34, 12, 20 → largest = 34

After Step IV:
Bounce Echo Gravity Mirror Shine 12 20 34 50 73 91

Now, Which word is at the 3rd position from the left in Step IV?

In Step IV:
Bounce (1) Echo (2) Gravity (3) Mirror (4) …

Thus, correct option is (b).
