Local string variable not initializing error

I have searched the forum for this error but can't seem to figure it out.
Why are the variable q2,q3 not being initialized, yet q1 is? Thanks all help is appreciated.

This is how the outcome should be similar to:

WELCOME TO MITCHELL'S TINY ADVENTURE!

You are in a creepy house! Would you like to go "upstairs" or into the "kitchen"?

kitchen

There is a long countertop with dirty dishes everywhere. Off to one side there is, as you'd expect, a refrigerator. You may open the "refrigerator" or look in a "cabinet".

refrigerator

Inside the refrigerator you see food and stuff. It looks pretty nasty. Would you like to eat some of the food? ("yes" or "no")

no
