Galvanic Cell

Q. Assume that you want to construct a voltaic cell that uses the following half reactions: A^2+(aq) + 2 e^- → A (s) E°red = -0.10V B^2+(aq) + 2 e^- → B (s) E°red = -1.06V You begin with the incomplete cell pictured below, in What additions must you make to the cell for it to go generate a standard emf? Check all that apply.
