After vacuuming for a few minutes, Jack tripped over the vacuum's long electrical cord, fell, and broke his ankle.Jack went to the hospital ER via ambulance.A walking cast was applied to the ankle after it was determined he did not need surgery.Jack missed a week of work.

Will GC be liable for negligence for Jack's injuries, and why or why not?
