Directions: In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage.

The word "culture" comes from the Latin "colere," which 29 means "to cultivate." In other words, it refers to anything that is 30 or learnt, rather than instinctive or natural.

Like humans, killer whales have colonized a range of different 33 across the globe, occupying every ocean basin on the planet, with an empire that 34 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 35 that the ability to learn population-specific hunting methods could be driving the animals' genetic development.
