Rock samples taken from the remains of an asteroid about twice the size of the 6-mile-wide asteroid eradicated the dinosaurs has been dated to be 3.47 billion years old and thus is evidence of the earliest known asteroid impact on earth .

把SAMPLES看成一个整体(因来源于同一个ASTEROID)，所以用HAS.

这道题在语法区有讨论过，集中在c和e上，主要是date的用法。我倾向于选e

这个是用google搜的：

Living snails were C14 dated at 2,300 and 27,000 years old

我觉得这里"living snails" is 逻辑上不可能是2300, 27000 years old 把

同意选E。

我记得date at 是一个固定用法，但是一下子找不到例子了。

对于date的用法，实在很困惑。。偶在GOOGLE上查到下面两个例子，感觉不出be dated to be和be dated at有啥区别，还请高手指点。。

The crania of two adults and a child, all dated to be around 160,000 years old, were pulled out of sediments near a village called Herto in the Afar region in the east of the country.

Discovery of the buried crater near the Yucatan Peninsula, dated at 65 million years old.
