Key Quiz

 To differentiate the keys needed for various things, I ordered colorful key holders w/ the name of the thing they unlock embroidered on them.  Usually though there are two keys: in case something happens to the original or there are two people that want to have a key.  For the backup keys, I picked up key holders w/ the symbols for the given name.  Try matching the outside embroidered keyholders to the correct middle four keyholders w/ the symbol for that name.  See how much Norse mythology you know.
