parallelism & time sequencing is tested by this sentence

(A) the electrification of lighting in lower Manhattan doubled work efficiency when the energy costs were cut in half
doubled while cutting energy costs - more appropriate & parallel

(B) the electrification of lighting in lower Manhattan doubled work efficiency while cutting energy costs in half
looks good.

(C) the electrification of lighting in lower Manhattan doubled work efficiency while costs were cut to half
parallelism error
costs were cut - what costs?

(D) lighting electrification in lower Manhattan doubled work efficiency while energy costs were cut in half
parallelism error
lighting electrification - suspicious

(E) lighting electrification in lower Manhattan doubled work efficiency while costs were cut to half
same errors as in D
in addition -while costs were cut. what costs?

Hi mvictor,

Can you please explain if "costs in half" is correct usage? Cause I feel "costs by half" is correct usage.

Regards,
Dom.

None of the options seem correct here..

1) "cut in half" is wrong --> should be "cut to half" - better - or "cut by half" - best.

Bread loaf was cut in half. No one says energy costs were cut in half. C and E sound best of the lot,but they have issues as well.

Can't you say "He cut the bread loaf in half"? Similarly, they cut the energy cost(s) in half. I prefer by half too, but B was the best option to me and I was not able to find anything 100% incorrect

Cut X in half is same as "reduce X by 50 %"

Could you explain where you see the parallelism in the two forms ? egmat , could you shed some light on this ?

to cut X in half​ is to reduce X by 50%. 
Thus, it is idiomatically correct to say ​

'while cutting energy costs in half' 

to mean

'while reducing energy costs by 50%.'

From the above C and E are out.
moreover .. In E costs is ambiguous... We are unable to determine which costs were cut in half. That rules out E.

Coming to the rest of the choices...

Lighting electrification sounds as if it lighting evolved by itself. Not possible. Hence D is ruled out.
Problem with A is the word 'when'. We have to contrast 'doubling of work efficiency 'against 'reduction in energy costs'. Correct word that should be used is 'While'.

Hence the clear winner is 'B'
