正确答案: C

公园附近的农场主已经担心一旦重新引进灰狼，灰狼有时候会把他们的家畜作为猎物捕食。

题目：国家公园里没有灰狼出没已经好几十年了，管理公园的行政人员希望在不危害公园现存其他野生物种生存情况下重建灰狼种群。因为，在公园里灰狼有足够的猎物充食，灰狼也避免和人近距离地接触。因此重新引进灰狼可以在不严重危害游客安全的情况下实现公园行政人员的目标。如果下面每项内容为真，除了哪一项之外都加强上文的推理?

解析：解析：根据题干所给信息：引进灰狼，(1)不危害公园现存其他野生物种；(2)公园里灰狼有足够的猎物充食；(3)灰狼也避免和人近距离地接触；(4)不严重危害游客安全。分析题干可推出：只有C选项与公园里灰狼有足够的猎物充食相矛盾。而A、B、C、D四选项都加强了上文的推理。

It is important to the entire O0 industry to encourage broadly based tools and vendors, as well as niche products that cater to the needs of specialized groups.
