2 4. Base your answer to the following question on on the diagram below, which shows laboratory materials used for an investigation of the effects of sediment size on permeability, porosity, and water retention. Four separate columns, labeled A through D, were filled to the same level with different sediments. The sediments within each column are of uniform size. An equal amount of water is poured through each column. On the grid, draw a line to show the relative amount of water retained in the sediment after the water flows through each column.
