Devotion
Devotion: love, loyalty, or enthusiasm for a person, activity, or cause.
The grandfather was loyal to the store so devotion fits best.

The answer would be, "The remains of the pharaoh <u>are</u> intact, and the wrappings of the mummy <u>contain</u> clues about his life."

First protagonist.
It is from the the main character and only their perspective. First person usually captures the character's emotions and insight the best.
