Answer:
The soil that has more gravel is the soil that allowed less water to be collected.
Step-by-step explanation:
Gravel has the function of retaining water in a soil. Thus, the gravel makes it difficult to drain the water, leaving it stuck in the soil. In this case, students will not be able to collect much water from the soil sample that has more gravel. In other words, the soil with the most gravel has the least amount of water collected.
