Currently, the city of Grimchester is liable for any injury incurred because of a city sidewalk in need of repair or maintenance. However, Grimchester' s sidewalks are so extensive that it is impossible to hire enough employees to locate and eliminate every potential danger in its sidewalks. Governments should be liable for injuries incurred on public property only if they knew about the danger beforehand and negligently failed to eliminate it. Which one of the following describes an injury for which the city of Grimchester is now liable, but should not be according to the principle cited above? ['A person is injured after tripping over a shopping bag that someone had left lying in the middle of the sidewalk.', 'A person is injured after stepping in a large hole in a city sidewalk, and the city administration had first learned of the need to repair that sidewalk minutes before.', 'A person who is heavily intoxicated is injured after falling on a perfectly even city sidewalk with no visible defects.', 'A person is injured after tripping on a badly uneven city sidewalk, and the city administration had been repeatedly informed of the need to repair the sidewalk for several years.']
