Referring to the graph below, determine if each sequence of vertices is a path, circuit, or neither.

$Q,T,R,S,Q$

Using the graph below, determine which edges are NOT part of the path $P-Q-S-T-R$.

What is the length of the path $P-Q-S-T-R$?

Referring to the graph below, determine if each sequence of vertices is a path, circuit, or neither.

$P,P,Q,T,R$
