答案 [Professor]
    So we’ve been discussing The 8-Armed Einstein...Being incredibly flexible, octopuses can fit through spaces that are the same size as their eyeballs. Many a person who has had a pet octopus may have, at one time or another, thought that their pet had escaped, only to be surprised at finding it hiding somewhere in the fish tank...Besides being favored as pets, octopuses are also popular because they are quite tasty. But before you dig in to that next juicy piece of octopus, consider this: In recent years, measures of their intelligence have placed the octopus among the laureate of the marine animal world.
    It is now known that the octopus has an amazing ability to learn. Researchers have demonstrated that octopuses can remove lids from jars to get at food, and find their way through complicated mazes.
    Octopuses can learn by observing. With a system involving reward and punishment, scientists in Italy trained a group of octopuses to attack red balls in an aquarium containing both red and white balls. The scientists let another group of octopuses watch. Later, when the observing group was shown red and white balls, they went for the red ones.
Q: The professor describes some aspects of Octopuses’ fascinating behaviors. Explain why Octopuses might be labeled as intelligent animals with their ability to change skin color.
