A student places 250g samples of clay, sand, gravel, and silt in separate flower pots. The pots are set on a wire rack, and dishes are placed beneath the pots so that water can drip through holes and collect. The student then pours 100mL of water over the sample in each pot. The student measures the time it takes for water to begin dripping from the bottom of each pot. What property of soils is the student most likely examining in this procedure?

• The differences in texture between wet and dry soils.

• How well different soils retain water.

• How much water is needed to dissolve different soils.

• The amount of time it takes different soils to dry.
