问题         Just because they can’t sing opera or ride a bicycle doesn’t mean that animals don’t have culture. There’s no better example of this than killer whales. As one of the most【C1】_________predators (食肉动物), killer whales may not fit the【C2】_________of a cultured creature. However, these beasts of the sea do display a vast range of highly【C3】_________behaviors that appear to be driving their genetic development.
        The word "culture" comes from the Latin "colere," which【C4】_________means "to cultivate." In other words, it refers to anything that is【C5】_________or learnt, rather than instinctive or natural. Among human populations, culture not only affects the way we live, but also writes itself into our genes, affecting who we are. For instance, having spent many generations hunting the fat marine mammals of the Arctic, the Eskimos of Greenland have developed certain genetic【C6】_________that help them digest and utilize this fat-rich diet, thereby allowing them to【C7】_________in their cold climate.
        Like humans, killer whales have colonized a range of different【C8】_________across the globe, occupying every ocean basin on the planet with an empire that【C9】_________from pole to pole. As such, different populations of killer whales have had to learn different hunting techniques in order to gain the upper hand over their local prey (猎物). This, in turn, has a major effect on their diet, leading scientists to【C10】_________that the ability to learn population-specific hunting methods could be driving the animals’ genetic development.

选项
答案 G
解析 空格所在句意思是：同人类一样，虎鲸聚居在全球许多不同的___________。本句说明虎鲸在地球上分布很广泛，由此可推断空格处应填入含有“居住地，栖息地”意义的复数名词，故本题答案为habitats“栖息地，生活环境”。另外一个备选复数名词adaptations“改编版”不符合句意，因此排除。
