Don't understand the question in 'groups.py' challenge task 1/2

Having read the question for this task several times, I am afraid I do not understand what is being asked. Are we supposed to identify who is a member of a band from the list 'musical_groups', and then print these names out separately? If someone could break it down in its simplest form I'd be grateful!

Feedback - it's such a shame there is not a hint in this task as I am forced to ask a question. I remember previous tasks having hints which were very helpful.

groups.py 
musical_groups = [
    ["Ad Rock", "MCA", "Mike D."],
    ["John Lennon", "Paul McCartney", "Ringo Starr", "George Harrison"],
    ["Salt", "Peppa", "Spinderella"],
    ["Rivers Cuomo", "Patrick Wilson", "Brian Bell", "Scott Shriner"],
    ["Chuck D.", "Flavor Flav", "Professor Griff", "Khari Winn", "DJ Lord"],
    ["Axl Rose", "Slash", "Duff McKagan", "Steven Adler"],
    ["Run", "DMC", "Jam Master Jay"],
]
# Your code here
members = [
for group in musical_groups:
    print(", ".join(

Hi Alan,

Unless I’m misunderstanding what you mean with the term identify, you are not meant to decide who’s a member of the band. The question tells you the identity of the band members. Your job is to print each member as a string, separated by a comma. 

# Output: ‘Run’, ‘DMC’, ‘Jam Master Jay’

The output would look like the sample above, except it would include all bands, and each band would be printed on a different line.

Here a hint on how Treehouse wants you to solve this: nested for loops

Hope that helps! Good luck.

I knew I was just reading the question incorrectly, although I would say a prerequisite knowledge of who the names are in the list is required. I thought that some of the names were bands and some were members, all in a mix, but one quick search on Google made me realised they are all members! Anyway, I got the solution thanks to your help.
