So it's just lists inside of a list right? The 'first group' is a list of all the members of Beastie Boys the 'second group' is The Beatles ect.

I think you mean the first and second dimension, where the instructions say "The first dimension is group, the second is group members."

What they mean by "first dimension" is the outer list, the one that holds all the smaller lists of members. Each of its elements is a whole group.

The "second dimension" is the inner lists of just the members of the group.
