Researchers got the four pigs, [named / names] Ebony, Hamlet, Ivory and Omelet, to play a simple game at [difference / different] levels. They had to move a joystick with [their / them] snout to make a cursor move to a coloured wall. If they were successful, they got a [tasty / taste] treat.

A scientist told CNN that: "The pigs clearly understood the connection [between / among] their own behavior, the joystick, and [what / that] was happening on the screen."
