They never compromise on flexibility. And then the cell needed to change again. The pace of change these days can be punishing. And then the cell needed to change. Lets take a closer look.
a cell has 2 possible changes.
( z0 change :quant 2 :ARG1 ( z1 cell ) :ARG1-of ( z2 possible ) )
(z0 / change-01
    :quant 2
    :ARG1 (z1 / cell)
    :ARG1-of (z2 / possible-01))
a cell has 2 possible changes .
z0 :ARG1-of z2
z0 :quant 0
z0 :ARG1 z1
