Today there is a much larger selection of tasks that everyone has been assigned to$.$

The crew is worried some shape$-$shifting aliens may have infiltrated their ranks. Captain Red and Co$-$captain Lime each trust their own group of friends, but they do not have exactly the same friend group.

Red says, $"6$ of the tasks my friends were assigned to are the same as the tasks your friends were assigned to$.$ But only $2$ tasks were assigned to our mutual friends."
