哪个迷宫 是走到终点是指走到两个端点吗？ 还是走到哪里啊？

从最上面那个点走到最下面五个点的任意一点~

那那。。看看这个。。不好意思。。很难考古啊～～

考古学认为古代人们是从非洲迁徙去亚洲和欧洲的，有建筑物的证据可以证明这一点。在BC13000年到14000年间，他们的迁徙经过一个XX桥，这带之间有一段时间的雨季。作者认为通过雨季的时间可以判断人们迁徙的具体时间。问加强。选项是1.人们需要花很多年时间迁徙。2.雨季可以让非洲人民离开他们的栖息地3.事实证明在雨季之后欧洲和亚洲人口大增。另外两个选项不记得了，貌似都是无关的，我选第三个——by koncat（700,V36)

要不。。再看看这个。。总觉得很像。。不好意思。。

Charcoal from a hearth site in Colorado, 2,000 miles south of Alaska, is known to be 11,200 years old. Researchers reasoned that, since glaciers prevented human migration south from the Alaska-Siberia land bridge between 18,000 and 11,000 years ago, humans must have come to the Americas more than 18,000 years ago.
Which of the following pieces of new evidence would cast doubt on the conclusion drawn above?
A.    Using new radiocarbon dating techniques, it was determined that the charcoal from the Colorado site was at least 11,400 years old.
B.    Another campsite was found in New Mexico with remains dated at 16,000 years old.
C.    A computer simulation of glacial activity showed that it would already have been impossible for humans to travel south overland from Alaska 18,500 years ago.
D.    Using new radiocarbon dating techniques, it was proved that an ice-free corridor allowed passage south from the Alaska-Siberia land bridge at least 11,400 years ago.
E.    Studies of various other hunting-gathering populations showed convincingly that, once the glaciers allowed passage, humans could have migrated from Alaska to Colorado in about 20 years.

楼主觉得问题出在哪啊？数学难还是？

-- by 会员 serenashu (2010/10/24 19:27:56)

数学和语法吧。。平时怎么说数学再差也不会到48啊。。唉。。

完了，我数学也很菜~~你做起来时间紧张吗？

我今天最大的问题就是。。都不会。。都蒙。。的结果就是。。数学提前十分钟语文提前五分钟。。
