They could not【C2】________with the bear, whose strength, speed and claws【C3】________an impressive "small fire" weaponry.

If the ape-men had attempted to compete on those terms in the open, they would have been【C5】________to failure and extinction.
But they were【C6】________with enormous concealed advantages of a kind not possessed by any of their competitors.
