A grocer mops an aisle and leaves no warning sign; a shopper slips and fractures a wrist. Which pair of negligence elements does the unmarked wet floor most directly establish?

A store owes customers reasonable care, and mopping without posting a warning falls below that standard, so the unmarked wet floor supplies duty and breach. The fracture and its costs supply damages, and the causal chain supplies proximate cause; those are separate elements the claimant still has to prove. Strict liability does not apply, because routine floor cleaning is not an abnormally dangerous activity.
