Video Summary

The problem involves determining which pet resides in house A based on provided statements about four houses and their pets: a dog, a cat, a mouse, and a rabbit. By negating the statements and determining only one to be false, we identify contradictions in the assumptions about the pets' locations. Initially considering conflicting statements about a rabbit living in house A or C, it's discovered that negating the initial assumption resolves contradictions. Consequently, all other statements hold true, leading to the conclusion that a mouse resides in house A. Thus, the pet in house A is a mouse.
