Hi,
C & D are pretty close. Hard to choose one over the other. D sounds better because it looks more polished than C because D uses 'rating the likelihood' and C uses 'rate how likely'. I can't find any grammatical error in either of them.

IMO E as the original stem include may, so the answer choice cant have will

Responding to the public's fascination with-and sometimes undue alarm overpossible
threats from asteroids,
who is reponding ?? a scale or an anstronomers, eliminate A & B

a scale developed by astronomers rates the likelihood
that a particular asteroid or comet may collide with Earth.

A. a scale developed by astronomers rates the likelihood that a particular asteroid or
comet may
B. a scale that astronomers have developed rates how likely it is for a particular asteroid
or comet to
C. astronomers have developed a scale to rate how likely a particular asteroid or comet
will be to
D. astronomers have developed a scale for rating the likelihood that a particular asteroid
or comet will
E. astronomers have developed a scale that rates the likelihood of a particular asteroid or
comet that may

Hi,
When we use likelihood, there should be some event or occurrence of something.
D clearly mentions the likelihood of the event 'that an asteroid will collide'
But, in E, it says likelihood of a asteroid. Moreover, likelihood is itself not certainty. Using 'may' again is redundant.
Doesn't it look incorrect?

I am with D.
E cant be. Likelihood already conveys chance. May is redundant.
Also in E, a scale that rates.. It is not the scale that rates, it is the astronomers.

IMO C

Hi,
I don't think that has anything to do with parallelism. The 'to' in 'to collide' comes from 'likely to'

Adding to above post. they are not meant to be paralleled. Scale is to rate and to collide Earth? NO

I am with D too for most of the reasons mentioned above but I am not sure of one idiom usage rating the likelihood that

hey even i feel it should be D. I am confused. Your point seems correct.
