Problem 10 - Entrance Test

A study compared the water retention capabilities of three different soil types (Sandy, Loamy, Clay) over a 24-hour period after saturation. The graph shows the percentage of initial water content remaining in each soil type over time. [Imagine a line graph with three distinct lines: x-axis: Time (hours) from 0 to 24. y-axis: % Water Remaining. Sample data (conceptual): - Sandy: Starts at 100%, drops quickly to 50% at 2h, 30% at 6h, 10% at 24h. - Loamy: Starts at 100%, drops to 70% at 2h, 50% at 6h, 30% at 24h. - Clay: Starts at 100%, drops slowly to 90% at 2h, 80% at 6h, 60% at 24h.] Which soil type lost water most rapidly in the first 6 hours?

Correct: A

To determine which soil type lost water most rapidly, we need to look for the line with the steepest negative slope (the quickest drop) in the first 6 hours. - Sandy soil drops from 100% to 30% (a 70% loss). - Loamy soil drops from 100% to 50% (a 50% loss). - Clay soil drops from 100% to 80% (a 20% loss). The sandy soil shows the largest percentage decrease in water content over the first 6 hours, indicating the most rapid water loss.
