Rachel and Matt believe that magnet 2 is responsible for the elevated position of magnet 1. Which two updates could be made to the model to help gather more evidence? A. Drop two more magnets on the top of the stack and observe whether or not the interaction between magnet 1 and 2 changes.

B. Remove magnets 2, magnet 3, and magnet 4 from the wooden dowel and observe whether or not magnet 1 remains elevated

C. Remove magnets 1 and 2 from wooden dowel, but keep the orientation of magnet 3 and magnet 4 the same.

D. Drop one more magnet on the top of the stack and observe whether or not the interaction between magnet 1 and magnet 2 changes

E. Remove magnet 3 and 4 from the wooden dowel, but keep the orientation of magnet 1 and magnet 2 the same.
