a)or double the rate in 2010
b)double that of 2010's
c)or twice the rate of 2010
d)twice that of 2010---- this seems to be the best one out of the all but I think instead of of it should be in. That refers to the amount of fresh water produced by desalination plants
e)twice the rate in 2010
Is the sentence from valid source????

twice is an adverb and can't be used as an adjective or noun. So that eliminates C, D and E.
"or" in option A indicates that either the volume exceeded by "50 billion gallons a year" OR by double the rate in 2010. This error is also present in option C.
Only option remains is B.
b)double that of 2010's
c)or twice the rate of 2010

For amounts and Quantity Words comparision, We should not use Double, but we rather use twice or thrice.....
So A and B are eliminated......
C is wrong because of use of word OR at start of sentence.....
E is wrong because of the usage the the rate in, but it is the amount.....
D is correct because it tells twice the amount of 2010 and is correct comparision..
OD is D

Hi -- One more reason why option C & E are incorrect---it is grammatically incorrect to say "Twice the rate of or twice the rate in, respectively"GmatKiss wrote:Scientists predict that by 2026, the amount of fresh water produced by desalination plants will exceed 50 billion gallons a year, or double the rate in 2010.
a)or double the rate in 2010
b)double that of 2010's
c)or twice the rate of 2010
d)twice that of 2010
e)twice the rate in 2010

We should use "Twice that of" when doing a Comparison.
For example -- Apple iPhone user loyalty twice that of Android
or take one more example-- Android Market attrition rate is twice that of Apple's App Store
Other members have already explained why option A is incorrect (incorrect usage of "OR")
Option B is awkward (2010's)
Therefore, Option D is the correct option.

a)or double the rate in 2010
Proper idiom is 'rate for'
b)double that of 2010's
c)or twice the rate of 2010
'rate of' is idiomatically incorrect. Proper idiom is 'rate for'
d)twice that of 2010
e)twice the rate in 2010
Proper idiom is 'rate for'
I'd pick D because the possesive for 2010 looks funny in B.

I don't know what to say, really. Three minutes to the biggest battle of our professional lives. You find out life's this game of inches, so is football. Because in either game - life or football - the margin for error is so small. I mean, one half a step too late or too early and you don't quite make it. One half second too slow, too fast and you don't quite catch it. I'll tell you this, in any fight it's the guy whose willing to die whose gonna win that inch. That's football guys, that's all it is. Now, what are you gonna do?

Rate for 2010 in this argument will mean year 2010 occurs after 2026, which is ambiguous!edvhou812 wrote:a)or double the rate in 2010 - Correct
Proper idiom is 'rate for' - is not valid in this argument.
b)double that of 2010's (2910's what?)
c)or twice the rate of 2010 - CONTENDER
'rate of' is idiomatically incorrect. Proper idiom is 'rate for'- is not valid in this argument.
d)twice that of 2010 - what in 2010?
e)twice the rate in 2010
Proper idiom is 'rate for'
I'd pick D because the possesive for 2010 looks funny in B.
Please correct me if am wrong!
