Problem Analysis:

The image contains a set of brain teasers and puzzles. Let's solve each one step by step.

#### 1. Rebus Puzzle:
The rebus puzzle is represented as:
```
SHORT
LONG
STREET
```

- Solution:
The rebus "SHORT LONG STREET" can be interpreted as a play on words. The key is to combine the words in a way that makes sense. Here, "SHORT" + "LONG" = "SHORT AND LONG," which together form "STREET."
Therefore, the answer is: AND.

#### 2. Riddle:
"What is that which is often set upon a table, often cut, but never eaten?"

- Solution:
This riddle describes something commonly found on a table, often cut (with scissors), but not consumed. The answer is: A PIECE OF PAPER or PIECE OF CAKE (as in a dessert). However, the most fitting answer is PIECE OF PAPER, as it aligns with the context of being "cut" without being eaten.

#### 3. Riddle:
"Why ought a fisherman to be very wary?"

- Solution:
This riddle plays on the idea of danger or caution. A fisherman should be wary because they are dealing with water, which can be dangerous (e.g., drowning, slippery surfaces, strong currents). Additionally, fishing involves handling sharp tools like hooks and knives.
Therefore, the answer is: BECAUSE HE IS SURROUNDED BY WATER AND SHARP OBJECTS.

#### 4. Wordplay:
"Spell 'eye wear' with four letters."

- Solution:
The phrase "eye wear" refers to glasses. To spell "glasses" using only four letters, we need to think creatively. The word "eyes" fits perfectly, as it is a common colloquial term for glasses.
Therefore, the answer is: EYES.

#### 5. Decoder Puzzle:
The decoder puzzle is represented as:
```
MIND
MATTER
```
Below it, there is a grid:
```
5 5 S S
B B B B
A A A A
R R R R
G G G G
```

- Solution:
This puzzle involves mapping letters to numbers. Each row corresponds to a letter in "MIND MATTER." We need to decode the pattern:
- The first row has two "5"s and two "S"s.
- The second row has four "B"s.
- The third row has four "A"s.
- The fourth row has four "R"s.
- The fifth row has four "G"s.

By observing the pattern, we can infer that:
- "5" maps to "M"
- "S" maps to "I"
- "B" maps to "N"
- "A" maps to "D"
- "R" maps to "M"
- "G" maps to "A"

Thus, the decoded message is: MIND MATTER.
