Weaken: A
P: many large herbivores such as deer and moose are grazing around the newly construction road.
P: The reported numbers are about equal to our overall population estimates of the past three years
C1: if there are that many near the road, the animals must be even more abundant in more distant reaches of the forest.
Main Conclusion: concerns that local populations of these animals are threatened by the construction of the new highway are clearly misplaced
A:不一定森林深处更多因为有食肉动物的存在， 食肉动物不愿意靠近公路 – 削弱结论
