Recently, evidence was found near Lake Baringo in Kenya that may have been the earliest known use of fire by ancestors of Homo sapiens.

(B) Recently found near Lake Baringo in Kenya was evidence of what may have been

(C) Evidence that was recently found near Lake baringo in Kenya may have been

(D) Near Lake Baringo in Kenya, evidence was recently found that may be

(E) Found recently near Lake baringo in Kenya is evidence that may be what was

Key is B, 求教思路????/

CDE的错误 都是evidence 和对其修饰的定语，the earliest known use of fire by ancestors 分开了

我个人认为对于evidence来说

某个东东是什么什么(the earliest use)的evidence

但是这个evidence 不是 the earlist use
