[单项选择] Some animal behaviorists argue that certain animals can remember past events,
anticipate future ones, make plans and choices, and coordinate activities within
a group. These scientists, however, are cautious about the extent to which animals

(5) Explanations of animal behavior that leave out any sort of consciousness at

[填空题]International trade develops because certain countries are able to produce some goods more efficiently than other countries. They exchange goods to satisfy their needs and wants. Efficient production may be the result of several factors. A certain climate in a particular country may allow that country to grow agricultural products in large quantities.
