Please Explain

Hi SMA, I think we have uneven/uncertain numbers here. We have seven volunteers, and two committees. However, we are never told that every volunteer must be on a committee, nor that each volunteer can only be on one committee. I think that (with the exception of F and K) the volunteers can be on both committees- so 5 would be on both, and F/K would serve as the sixth on either committee

I must be mistaken in thinking they are asking how many each group can have in common? Meaning F and K are in different groups which gives the number in common for each group 5. F & K J & J M & M G & G H & H L & L We have the top up top not in common. Count the other similarities and we have 5. Im obviously wrong, but that is how I read it. How can I read it next time and not miss it?

I think a better way of putting it that I was able to last year is that we could have all five of the non f/Ks on both committees, and then then one of f or k as the sixth on both. This would mean the two committees would have identical rosters. It would look a bit like this P: G H L M J K T: G H L M J K We could also replace the Ks with Fs.
