Which choice most logically completes the text?

Bees tend to have higher cognitive abilities. This was demonstrated in a series of experiments where real bees were made to learn an unnatural task of moving a small ball to a goal to gain a sugary reward. They tend to copy the task just after few observations. In order to understand how this learning was possible in the tiny brains of the bees. Scientists tested three groups of bees. One group of bees watched another previously trained bee move the ball to the goal. Second group watched the ball moving on the goal on its own. And third group did not receive any demonstration. All ten bees of the first group solved the task much quicker and are a higher success rate than either of the other groups. While the group which learned by watching the ball move on its own did significantly better than the bees who did not receive any demonstration.
