Thus, the design is constrained by the range of current production motorcycle, and will be compared using miles/kWh.

Convert the sentence from passive to active voice.


It's a bad sentence to begin with. You can't compare just one design, and it is difficult to imagine how a design might be expressed in mi/kWh.

So I'm going to assume that what is meant is that it is what is to be compared is the ranges of two motorcyles: a current production model and a new design. And to cast the whole in the active voice will require introducing an Agent who performs the comparison.

The range of the current production motorcycle constrains the design, and we will compare the ranges using miles/kWh.

But speaking of a range constraining a design is not very good either. What is probably meant is something like:

A constraint on the design is that its range should be at least equal to that of the current production model. We compare them in miles/kWh: &c

  • @FumbleFingers When I see questions like this I generally blame it on OP's teacher, not OP, and try to provide something for lagniappe. Of course if it's a homework question and OP turns in either of my sentences they may get whacked ... – StoneyB on hiatus Mar 27 '15 at 0:35
  • I find it hard to believe even the most incompetent teacher would present that as a homework question.I'd guess the boss told his office junior to smarten up some documentation, and convert all passive constructions to active voice (perhaps to make them more accessible, or maybe just the boss's foible). – FumbleFingers Reinstate Monica Mar 27 '15 at 0:40
