They could not 【B1】______ with the bear, whose strength, speed and claws 【B2】______ an impressive ’smallfire’ weaponry. They could not even defend themselves 【B3】______ running swiftly like the horses, zebras or small animals. If the ape-men had attempted to compete on those terms in the open, they would have been 【B4】______ to failure and extinction. But they were 【B5】______ with enormous concealed advantages of a kind not possessed by any of their competitors.
In the search 【B6】______ the pickings of the forest, the ape-men had 【B7】______ efficient stereoscopic vision and a sense of colour that the animals of the ’grasslands did not possess. The ability to see clearly at close range permitted the ape-men to study practical problems in a way that lay far 【B8】______ the reach of the original inhabitants of the grassland. Good long- distance sight was 【B9】______ another matter. Lack of long-distance vision had not been a problem for forest-dwelling apes and monkeys because the higher the viewpoint, the greater the range of sight so 【B10】______ they had had to do was climb a tree.

选项
A、available
B、enough
C、sufficient
D、convenient
答案
B
解析
词汇辨析能力。从上下文看,用“足够的”这一意思较适合。enough表示相对某一特定具体目的、意图等,“足够的”、“够用的”。sufficient表示“充足的”,可能还有盈余。前者显然更适合本句。
