Mossberg 500 Shotgun Final 6 Quiz Questions!

I am semi-retired and I am taking a self-passed and self-taught Armorers course on Mossberg 500 Shotguns. I hope to become a part-time light Gunsmith in the future.

There are over 60 quiz questions covering this firearm and I have answered most of them. During my study and research I am having some problems related to some of the following Final 6 quiz questions. Either I am not sure of the correct answer or I have conflicting answers.

Can you help me determine the correct answers for these few final 6 quiz questions?
