Paragraph 3 supports which of the following inferences about the effect of vegetation on soil? A. The root systems of most crops are unable to prevent erosion on sloping ground. B. Without a cover of vegetation, fast running water is likely to disappear from the ground surface before it can erode much of the soil. C.
