Question

To remember my great vacation in Vancouver, I brought back two a city map and a lovely bracelet

Answer 1

Ablutions=the act of washing oneself. 
mementos=an object kept as a remainder or souvenir of a person or event. 
protocols=the official procedure or system of rules governing affairs of state or diplomatic occasions. 
manacles=a metal band, chain, shack for fastening someone's hands or ankle. 
Therefore, the answer is mementos. I suspect that they put manacles as a tricky answer since they mentioned about the bracelet. But manacles meant to fasten someone's hands or ankle with chain like prisoners. 
Hopefully, that helps you.
