B.    appear to have been equipped to face any obstacle the environment could put in their path,
C.    appear as equipped to face any obstacle the environment could put in their paths,
D.    appeared as equipped to face any obstacle the environment could put in their paths,
E.    appeared to have been equipped for facing any obstacle the environment could put in their paths,

同问。 对path和paths的解释也不懂

connie飘着

主句 是  THE  NEANDERTHALS, 应该是个复数，后面BUT 。。。INDICATES 说明前面应该用现在时，因为是陈述一件事情，前后时态一致。 前半句是要说 他们已经准备好了去面对一切， APEAR 的用法就是  TO DO STH  /TO BE STH.   EQUIP 表示当时的状态，应该是已经准备好了，所以用完成时啊。
至于 PATH, 可数名词， 在他们的道路上，他们的路应该只有一条吧！
