Is the answer provided by CAS wrong for 8b?
It says that Group #2: Combine old group #3 & #5 into new Group #2 but #5 is onerous. I think #3 and #4 should be grouped into a new group, and #5 should stand alone.
Please confirm.
Yeah looks like there is a typo on the CAS' end. Your groupings are fine
