It worked great for years. 2. 3. Recently, however, the engineer who told me this story let me know there was a happy ending. Do I qualify?
the disk use worked well for years.
( z0 work :ARG1 ( z1 use :ARG1 ( z2 disk ) ) :ARG1-of ( z3 well ) :duration ( z4 multiple :op ( z5 temporal-quantity :quant 1 :unit ( z6 year ) ) ) )
(z0 / work-09
    :ARG1 (z1 / use-01
              :ARG1 (z2 / disk))
    :ARG1-of (z3 / well-09)
    :duration (z4 / multiple
                  :op1 (z5 / temporal-quantity
                           :quant 1
                           :unit (z6 / year))))
the disk use worked well for years .
z1 :ARG1 z2
z0 :ARG1 z1
z0 :ARG1-of z3
z0 :duration z4
z4 :op1 z5
z5 :unit z6
z5 :quant 0
