2nd weighing, before that, you have to start moving marbles around, and using your known marbles, you have to create a control group b4 the 2d weighing.
Create a control group based on known marbles. Use that control group to make the 2nd weighing, and identify the bad marble. That's your goal on the 2nd weighing. You may be left with 2 marbles. That's ok. You got this!
