**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? [Text Box]
