Source: GMAT Prep

New equipment and other improvements reduced the amount of time---from eleven hours in 1982 to six in 1988---needed by workers so that they could produce a ton of steel.

A. needed by workers so that they could produce
B. needed when workers are producing
C. workers need in producing
D. workers needed to produce
E. workers need for their producing of

OA: D

I just confused that what could be the subject.

"New equipment and other improvements" OR "workers "??

Time needed by workers is passive; Time workers need/needed is active.
C and E are incorrect. Pick D.

IMO C

I think : subject is "New equipment and other improvements"

reduce the time workers need in producing...

D is passive construction.

OA ?

IMO C
as it is time not number of workers.
If we pick D it would be mean workers are reduced but since 11 hours is given.It can be workers however D seems to be gramatically correct but logically incorrect.
GMAT score is equally counted as your GPA and 78 clicks can change you life.

I mentioned OA in first post.

I would like to understand following.

New equipment and other improvements reduced the amount of time workers needed to produce a ton of steel.

"workers" seems to me as a stand alone. There should be some preposition around workers. This is reason that D looks odd to me. However, D is best option.

This is the official problem and D is the right answer. I have to eliminate confusion. Can someone help me?
