A resolution technique. When coupled with a complete search algorithm, the resolution rule yields a sound and complete algorithm for deciding the satisfiability of a propositional formula, and, by extension, the validity of a sentence under a set of axioms.
Handling Move Outs-when a tenant moves out, the manager is responsible for inspecting the unit, checking for damages and determining what portion of the security deposit will be returned to the tenant. After move out, they are responsible for cleaning the unit, repairing any damages and finding a new tenant.
If the tenant's negligence caused the fire, as opposed to, say, faulty equipment (in which case the landlord could be liable, if it was the landlord's equipment that is at fault, such as a kitchen stove that malfunctioned), then the tenant would ultimately be liable for the damage.
