Answer:
B. Pigs can be taught a variety of games, which can increase their intelligence.
Step-by-step explanation:
The article discusses how pigs are able to learn how to play video games by using their snouts to manipulate a joystick, and how this can increase their cognitive abilities. While the first central idea of the article is that pigs can learn to play video games, the second central idea is that this ability can have implications for our understanding of animal intelligence. Option B restates this second central idea by emphasizing the fact that pigs can learn a variety of games, which can in turn increase their intelligence. The article suggests that this discovery challenges traditional views of animal intelligence and has the potential to lead to new research on animal cognition and communication, which may have implications for both animal welfare and human-animal interactions.
