Q9:

The population of desert tortoises in Targland’s Red Desert has declined, partly because they are captured for sale as pets and partly because people riding all-terrain vehicles have damaged their habitat.  Targland plans to halt this population decline by blocking the current access routes into the desert and announcing new regulations to allow access only on foot.  Targland’s officials predict that these measures will be adequate, since it is difficult to collect the tortoises without a vehicle.

Which of the following would it be most important to establish in order to evaluate the officials’ prediction?

1. Whether possessing the tortoises as pets remains legally permissible in Targland
2. Whether Targland is able to enforce the regulations with respect to all-terrain vehicle entry at points other than the current access routes
3. Whether the Red Desert tortoises are most active during the day or at night
4. Whether people who travel on foot in the Red Desert often encounter the tortoises
5. Whether the Targland authorities held public hearings before restricting entry by vehicle into the Red Desert

答案是B，请哪位NN帮我分析一下思路呀，谢谢~~

在T的desert，toroise数量少了。因为被抓和汽车污染，而被抓也和汽车有关。

所以T决定禁止旅客开车进去。那如果非法捕猎者开车进去，而不走旅游路线呢？

假如真这样，T不是白忙活了么。

所以要选B。

简单看来，为解决一个问题，T提出一个方案，评价这个方案的可行度，是否能达

到解决问题的关键。

所以答案一定和方案有关。就是“禁止开车进入沙漠”有关。ACDE都无关。

谢谢楼上的NN,题目分析得很清楚.但是想问一下,B的选项的意思是"是否T能够实施对于旅游车除了目前的进入通道以外,其他通道都不准旅游车进入的法规",是这个意思么?就是说是否目前的进入通道以及其他通道都不准旅游车进入?

谢谢~~~~
