Astronomers

[zagcollins]

Responding to the public’s fascination with-and sometimes undue alarm over-possible threats from asteroids, 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.

OA is C

[Dante]

I go with C (will looks bad)

E also looks fine (but feel to is required). Please clarify.

[ricky]

IMO c.
E is undiomatic and changes the meaning of original sentence

What is OA?

[reachac]

IMO D

[lvincy]

I will go with D

[kiranlegend]

IMO D.. what's OA?

[Vignesh.4384]

Hi,

IMO D.

C does not seem to be a good option.
between D and E .. D maintains parallelism..

[rolodex]

IMO C

C. commet will be likely to collide .................. (this is the right way)

[ildude02]

C is my pick. I think using "will" in D along with the word "likelyhood" which means it's not certain is not correct. The word that fits the "uncertain" event is "may" . E changes the meaning to say that sclae rates its self instead of C which says, scale is "used" to rate. Not sure if my reasoning is OK.

[Aldiablo]

IMO C.

AB wrong modifier

D changes meaning from comets may collide to comets will collide.

E 'that' should be have been 'which'.

Hi ,

Why do u need the word may here ? the word likelihood intrinsically that it might or might not collide ..
so i thought we could do away with that word may.

Please correct me if i am wrong.

Basic skeleton is like -
measure likelihood of X that may do Y.

So likelihood does not necessarily mean that it may not collide. So 'may' is required. IMO.
