Now do this put-the-text-back-together activity.
This is the text (if you need help).
Pigs are intelligent and can play video games. Researchers tested their gaming skills. The researchers got four pigs to play a simple game at different levels. They moved a joystick with their nose to move a cursor. If they did it, they got a treat. The lead researcher said the pigs could understand what to do.
The pigs spent many days playing the game on three different levels. The higher levels had nicer treats. A scientist said: "The pigs clearly understood the connection between their own behavior, the joystick, and what was happening on the screen." The researchers want to understand how pigs learn and understand.
Back to the pigs lesson.
