**Question 8**: Does the following graph have an Euler path? Why or why not?

**Graph Description**:
The graph consists of connected line segments that form the letters "CUBS". Each letter is constructed using vertices (represented by dots) and edges (represented by lines connecting the dots).

**Detailed Explanation**:
- **Letter "C"**: 
  - Vertices: 6 
  - Edges between vertices form an open shape resembling the letter "C".

- **Letter "U"**: 
  - Vertices: 4 
  - A shape resembling "U" with two vertical lines connecting to a horizontal bottom line.

- **Letter "B"**: 
  - Vertices: 6
  - The letter "B" is formed by two loops vertically connected by a central vertical line.

- **Letter "S"**: 
  - Vertices: 5
  - A zig-zag shape forms the letter "S".

**Euler Path Explanation**:
An Euler path is a path in a graph that visits every edge exactly once. A graph will have an Euler path if it has exactly 0 or 2 vertices of odd degree. Counting the degree of each vertex in this graph helps to determine the presence of an Euler path.

**Conclusion**:
To determine the existence of an Euler path, check the degree of each vertex:
- For vertices with odd degrees, the graph should have exactly 0 or 2 to have an Euler path.

Analyzing the graph visually for vertex degrees would allow a determination of whether an Euler path exists in this case.
