Problem Analysis:

The task requires forming four-letter words and five-letter words using the given letters. The structure of the words must follow the pattern provided in the image:

- Beginning: The word must start with "br."
- Middle: The middle part can be one of the letters: `a`, `e`, `ai`, or `o`.
- Ending: The ending can be one of the following: `n`, `t`, `ng`, `wn`, or `nd`.

Solution Approach:

1. Four-Letter Words:
- The format is: `br + Middle + Ending`.
- We need to combine "br" with one letter from the "Middle" column and one letter from the "Ending" column to form valid four-letter words.

2. Five-Letter Words:
- The format is: `br + Middle + Ending`.
- Here, we need to combine "br" with a two-letter combination from the "Middle" column (specifically "ai") and one letter from the "Ending" column to form valid five-letter words.

Step-by-Step Solution:

#### 1. Four-Letter Words:
We will try all possible combinations of "br" + "Middle" + "Ending":

- br + a + n: bran
- br + a + t: brat
- br + a + ng: brag
- br + a + wn:rawn (invalid as it doesn't start with "br")
- br + a + nd: brand
- br + e + n: bren (not a common English word)
- br + e + t: bret
- br + e + ng: bren (not a common English word)
- br + e + wn: brown
- br + e + nd: bred (not a common English word)
- br + o + n: bron (not a common English word)
- br + o + t: brot (not a common English word)
- br + o + ng: bong (slang term, may not be suitable)
- br + o + wn: brown
- br + o + nd: bond

From the above, valid four-letter words are:
1. bran
2. brat
3. brag
4. brand

#### 2. Five-Letter Words:
We will use "br" + "ai" (from the "Middle" column) + "Ending":

- br + ai + n: brain
- br + ai + t: bait (invalid as it doesn't start with "br")
- br + ai + ng: bring
- br + ai + wn: brawn
- br + ai + nd: brand (already used as a four-letter word)

From the above, valid five-letter words are:
1. brain
2. bring
3. brawn

Final Answer:

```
Four-Letter Words:
1. bran
2. brat
3. brag
4. brand

Five-Letter Words:
1. brain
2. bring
3. brawn
```
