less work being done over a shorter period of time.
the same amount of work being done over a longer period of time.
the same amount of work being done over a shorter period of time.

Answer 2

I would guess through logic that it is "the same amount of work being done over a shorter period of time" because
less work being done over a shorter period of time
and
the same amount of work being done over a longer period of time
and
less work being done over a longer period of time.
seem to mean the same thing that less work is being done, while the last one means more work is being done which would probably use more energy.
