The task in the image is a word ladder puzzle where you need to change one letter in each word to form a new word, ultimately completing the word ladder. The goal is to transform the starting word "BRAIN" into the ending word "SMART" by changing one letter at a time.

Step-by-Step Solution:

1. Starting Word: BRAIN
2. Change one letter to form the next word:
- BRAND (Change 'I' to 'D')
3. Continue changing one letter at a time:
- BRAND → BRANDS (Change 'N' to 'S')
- BRANDS → BRADS (Change 'N' to 'D')
- BRADS → BRATS (Change 'D' to 'T')
- BRATS → BATS (Remove 'R')
- BATS → BATE (Change 'S' to 'E')
- BATE → BAKE (Change 'T' to 'K')
- BAKE → MAKE (Change 'B' to 'M')
- MAKE → MARE (Change 'K' to 'R')
- MARE → MARK (Change 'E' to 'K')
- MARK → MART (Change 'E' to 'T')
- MART → SMART (Change 'E' to 'P')

Final Answer:

The completed word ladder is:
```
BRAIN
BRAND
BRANDS
BRADS
BRATS
BATS
BATE
BAKE
