![**Which or neither?**
Consider the following graph:
(Graph Explanation)
The graph consists of nine vertices labeled \(a\), \(b\), \(c\), \(d\), \(e\), \(f\), \(g\), \(h\), and \(k\). The vertices form a grid-like structure with the following connections:
- Vertices \(g\), \(h\), and \(k\) are connected horizontally across the top.
- Vertices \(a\), \(b\), and \(c\) are connected horizontally across the bottom.
- Vertices \(g\) and \(d\), \(h\) and \(e\), \(k\) and \(f\) are connected vertically.
- Vertices \(d\) and \(e\), \(e\) and \(f\), \(d\) and \(b\), \(e\) and \(b\), and \(f\) and \(c\) are connected horizontally and diagonally.
- Additional diagonal connections exist between \(g\) and \(e\), and \(h\) and \(f\).
**Questions:**
1. Does this graph have any Euler paths? (Enter yes or no)
[Text Box]
2. Does this graph have any Euler circuits? (Enter yes or no)
[Text Box]
3. What is the chromatic number of this graph?
