Convert the following NFAs into equivalent regular expressions. Show all the intermediate steps $($i$.$e$.$ GNFAs$)$ and make appropriate comments to help graders understand your steps.

For example, step $1$: remove state $"q_0"$; step $2$: remove state $"q_3",$ etc.

Convert the NFA in Figure $1$ into an equivalent regular expression.
