In the Reclamation Office you find; 3 sticks of gum (empty wrappers were tossed out), 7 paperclips, 1 pocket calculator, 1 lunch box (thankfully empty), 1 Merriam-Webster's Unabridged Dictionary, 2 baseball caps, 1 bottle of soda (quite flat), 12 marbles, 4 6-sided dice, a deck of cards, a razor (for shaving), a screwdriver, and a copy of the Federalist Papers. Unfortunately, you don't find an ID card.
Sector C does have its own reactor, Reactor 3, which is inactive. It seems that the Backup Generator in Sector C was activated 45 minutes ago. Interesting. There is one network hub on every floor, for convenience and accessibility. Each sector has its own Air Filtration and Water Purification facilities. Sector C seems to mostly be utility stuff though, the Cafeteria, Laundry Room, Incinerator, stuff like that.
In the laundry room there is quite a bit of laundry. Some clean, some dirty. There are also several washing machines and dryers. Some are closed, some are open. There is also a locked closet. The door looks like it could be broken with the proper tools.
