Final answer:
Harrison was able to break the laws of gravity because he freed himself from the physical constraints of handicaps.
Step-by-step explanation:
Harrison, the character in the story who freed himself from handicaps, was able to break the basic laws of gravity because he was no longer bound by the constraints of his handicaps. Handicaps are devices that were imposed on individuals in the story to equalize their physical abilities and prevent them from excelling. Once Harrison freed himself from these handicaps, he was able to move freely and perform feats that defied gravity.
