Answer
Various groups, including the Red Cross, the United Nations, and local governments, helped earthquake victims by providing food, shelter, and medical aid. However, some of the negative outcomes of the aid included the spread of disease due to overcrowding in shelters, the lack of access to clean water, and the difficulty of providing aid to remote areas. Evidence from the text includes the description of the "overcrowded and unsanitary conditions" in the shelters, the lack of access to clean water, and the difficulty of providing aid to remote areas due to the destruction of roads and bridges.
