Wp Get the full experience. Except she was wrong. The biggest data operation. But that assumption would be wrong. (No, that explanation doesnt make sense to me either.)
It costs a lot to challenge a data operation.
( z0 cost :ARG1 ( z1 challenge :ARG1 ( z2 operate :ARG1 ( z3 data ) ) ) :ARG2 ( z4 lot ) )
(z0 / cost-01
    :ARG1 (z1 / challenge-01
              :ARG1 (z2 / operate-01
                        :ARG1 (z3 / data)))
    :ARG2 (z4 / lot))
It costs a lot to challenge a data operation .
z0 :ARG2 z4
