GWD-第23套的一道纠结逻辑题，求指点！

wlihong

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?

A. Whether possessing the tortoises as pets remains legally permissible in Targland

B. ！Whether Targland is able to enforce the regulations with respect to all-terrain vehicle entry at points other than the current access routes

C. Whether the Red Desert tortoises are most active during the day or at night

D. Whether people who travel on foot in the Red Desert often encounter the tortoises

E. Whether the Targland authorities held public hearings before restricting entry by vehicle into the Red Desert

答案是B，我承认B是正确的，请哪位大神说服我，C是错的。。。。LZ觉得C也对，纠结了一下还是选了B，B比较符合套路，但真心觉得C也行。。

LZ我也不太说得好D为什么不对，但是下面是我的思路，试试看啊。
Question: 我们要基于哪一点之上来evaluate the official's prediction呢？
Officials’ prediction=these measures will be adequate
Measures:
1. blocking the current access routes into the desert;
2. announcing new regulations to allow access only on foot.
Reason:
It is difficult to collect the tortoises without a vehicle.

这题的关键是要evaluate这两个measures是否是adequate的。是需要我们tag到两个measures，而不是去challenge这个reason，我觉得这个reason是一个既定的事实。正是因为这个事实-difficult to collect tortoises without a vehicle, 所以Targland才plan the two measures. 这里的问题是针对于measures来的，要求我们找出能evaulate这两个measures的点。

不知道是不是这样，希望有大牛来解答。
