While working at the General Electric Research Laboratories, Dr. Irving Langmuir discovered that tungsten, which has an efficiency of more than 12 lumens per watt, can be used in incandescent lamps to replace carbon filaments, which have an efficiency of only 3 lumens per watt.
A.Dr. Irving Langmuir discovered that tungsten, which has an efficiency of more than 12 lumens per watt, can be used in incandescent lamps to replace carbon filaments, which have an efficiency of only 3 lumens per watt
B. Dr. Irving Langmuir discovered that tungsten filaments have an efficiency of more than 12 lumens per watt and can be used in incandescent lamps to replace carbon filaments, which have an efficiency of only 3 lumens per watt
C. Dr. Irving Langmuir's discovery was that tungsten filaments can be used in incandescent lamps to replace carbon filaments because it has an efficiency of more than 12 lumens per watt instead of only 3 lumens per watt
D. the discovery was made by Dr. Irving Langmuir that incandescent lamps can replace carbon filaments, which have an efficiency of 3 lumens per watt, with tungsten filaments, which have an efficiency of more than 12 lumens per watt
E. the ability in incandescent lamps to replace carbon filaments, which have an efficiency of 3 lumens per watt, with tungsten filaments, which have an efficiency of more than 12 lumens per watt, was discovered by Dr. Irving Langmui
this one got me!

I vote for B too.
First option compares 'tungsten' with 'acrbon filaments'.
Option C and D seem to suggest that the Discovery was working n the laboratories.
Option E suggests the ability to be working in the Laboratories.

I agree with this statement. pitts20042006 wrote: I vote for B too.
Option C and D seem to suggest that the Discovery was working n the laboratories.
Option E suggests the ability to be working in the Laboratories.
C, D and E are typical examples of Errors in Dangling modifiers.
In my opinion , answer is A or B.
B is more "parallel" construction ...so then... B!

look at comparisons:
A. tungsten - carbon filaments
B. tungsten filaments - carbon filaments
Maybe it isn't a classical example of parallelism, but I used " "

The Official Answer from kaplan is A...and i got it wrong.
In our case,
Dr Irving discovered that the tungsten can be used in incandescent lamps.
Thats the original idea of the sentence..isnt it.
in B..does that idea remain the same.
B changes the meaning. It says ...Dr Irving discovered that tungsten filaments have an efficiency of 12 lumens per watt...
But , thats not correct...isnt it.
Dr Irving only discovered that the tungsten can be used in incandescent lamps. we cant change the meaning of (A).
i dont think " tungsten" and " carbon filaments" is a big issue here
Do you even see a comparison?
i dont see "than" , "compared to" or " compared with"
thanks

I can see that there is infact no comparison ... but I found your explanation a bit confusing.
Could you please elaborate little bit more clearly in as much detail as ...

I didn't say that comparisons are from sentences...i said to look at mentioned compratisons...in sense of parallelism..
@Pretorian..you got a point there, B changes the meaning...
Where did you find this question?
