After reading the paragraph below, answer the questions that follow.
Scientists interested in knowing the best way to restore an area after a temporary road was built through it completed a study comparing two treatments: (1) restoring the contour of an area so that there was no longer a depression or cut-through where the road was previously and (2) simply abandoning the area to allow vegetation to return on its own. They wanted to know whether either or both of these treatments would return the aboveground vegetation and the belowground soil properties to their original state, as seen in a similar area where there had never been a road.
The researchers concluded, "These findings support the prediction that recontouring accelerates the rehabilitation of key ecohydrologica properties toward reference dynamics." What does this mean?
◦ Their original prediction that recontouring would produce greater plant diversity was supported.
◦ Recontouring makes the vegetation in the area grow out of control.
◦ Abandonment is the better treatment for restoration.
◦ Recontouring allows the water properties of the system to return to normal faster.
