Explanation 解释

The correct answer is 正确答案是.  。Place  is wrong because the slanted arrow doesn’t not point at any object on the map from this place.

这个地方不对，因为从这里出发，倾斜的箭头没有指向地图上的任何物体。

Place  is wrong; when placing one friend to cahce 1 and the other friend to cahce 2, their devices will arrow to this tree. But these friends are standing on the same place.

地点有误；当让一位朋友去藏 1 号物品，另一位朋友去藏 2 号物品时，他们的设备会指向这棵树。但这两个朋友站在同一个地方。

The  is wrong: probably you have chosen it because both arrows seem to point to this place. But we are not searching the target of these arrows but the place the arrows are going. 

这种想法是错误的：或许你选择它是因为两个箭头似乎都指向这个地方。但我们寻找的不是箭头所指的目标，而是箭头所去的方向。
