Graph (C, t ightarrow u ightarrow x ightarrow w ightarrow u ightarrow s ightarrow t ightarrow v

Graph \(C, t \rightarrow u \rightarrow x \rightarrow w \rightarrow u \rightarrow s \rightarrow t \rightarrow v \rightarrow w\)

Use the figure to answer the following exercises. In each exercise, a graph and a sequence of vertices are given. Determine whether each sequence of vertices is an Euler trail, an Euler circuit, or neither for the graph. If it is neither, explain why.
