参考答案和解析
正确答案： D
解析：
这道题问的是这块土地的再生需要多少年的时间。根据题干中的关键词regeneration，Hallside site可定位到F段“The specially raised hermaphrodites, which are self-impregnation, will spend the next five to ten years chewing their way through the topping layer to create a soil structure able to sustain long-term plant growth. Without them, the process could take up to 60 years”，意思是，如果使用这两种蠕虫的话则需要5到10年的时间，没有他们则要花费60年以上的时间，从上文中我们知道在土地再生过程中实际使用了这两种蠕虫，因此，这块土地的再生时间应该是5到10年。
