[kotokolin]

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 3.47billion years old and thus is evidence of the earliest known asteroid impact on earth

1) has been dated to be 3.47 billion years old and thus is
2) has been dated at 3.47 billion years old and thus
3) have been dated to be 3.47 billion years old and thus are
4) have been dated as being 3.47 billion years old and thus
5) have been dated at 3.47 billion years old and thus are






這套的key不知道什麼時候才出來, 我覺得應該是E
主詞rock samples, 所以A, B不能選
dated +at 是idiom(參考GWD8-34)
看來只能選E

您找的好詳細 我很想選C的
不過您的資料讓我再投您一票 E

投（E）再一票

查了一下網路，科學方面的文章裡 something be dated at (age) 是慣用法
