The one with the elephants.那个骑大象的汉尼拔将军 -
Okay, so the key here is going to be that there are two passes.好了 这里的关键问题是有两条路 -
One of these passes is a hard pass. It goes over the Alps.一条路崎岖 需要翻越阿尔卑斯山 -
And the other one is an easy pass. It goes along the coast.另一条路平坦 只需沿着海岸线走 -
If the invader chooses the hard pass如果侵略者选择崎岖的路 -
he will lose one battalion of his army仅在穿越阿尔卑斯山的途中 -
simply in getting over the mountains,他就要损失一个营的兵力 -
simply in going through the hard pass.这就是选崎岖之路的代价 -
If he meets your army, whichever pass he chooses,如果他碰巧遇到了你设防的途径 -
if he meets your army defending a pass,无论崎岖之途还是平坦之途 -
then he'll lose another battalion.他还要再损失一个营的兵力 -
I haven't given you--我还没有说完
