DISCUSSION: See lines 13-21. The fastest way to restore land is to replace the topsoil, but that’s difficult (lines 13-15).
Natural recovery is slow (lines 15-17).
The dutch study lets us speed up natural recovery (lines 18-21).
So the dutch methods are useful if we have to rely on natural recovery. But replacing topsoil would be faster.
The wrong answers all talk about problems caused by agriculture. The dutch methods are useful for accelerating recovery in all such cases.
- This is just a normal result of using land for agriculture (lines 7-8). The dutch study can help.
- CORRECT. Lines 13–15 say that replacing topsoil is the fastest way to restore land. So it may make sense to replace topsoil in cases where it’s easiest to do so.
The dutch method is only for when we’re relying on natural processes to restore land.
- Fertilization is a common agricultural practice that can help milk thistle grow (lines 8-11). Lines 30-34 show that the dutch study can help with this.
- Commercial grass plants and rye are never mentioned in the passage. This answer is just meant to confuse and mislead you.
- The passage never talks specifically about restoring land that is adjacent to current cornfields. This is misleading.
