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.

I think D is the correct answer.

A and B are wrong because "Responding.......asteroid" should modify "astronomers". C and E are wrong because of awkwardness.
Force and mind are opposites; morality ends where a gun begins.

IMO D

A and B eliminated as they both have modifier error.
C "a scale to rate how likely" is awkward and weird
E "likelihood" and "may" introduce redundancy.

Would any expert explain?

Awkwardness is not an explanation of a potential error. We MUST explain what makes something awkward.

Thanks.

imo E

'Responding' should modify a noun, hence astronomers and not a scale is required in the clause. Eliminate A, B.

Better word is 'likelihood' rather than 'how likely' Eliminate C

particular asteroid or comet will collide shows surety of this scenario happening, while its actually a possibility not a sure scenario. Eliminate D

E is right answer uses 'may' instead. Why are people discounting E? What is the OA ?

In E we have both likelihood and may - redundancy creeps in that sentence.

HTH!!

In addition to what krazy800 has written about redundancy,

We can have likelihood of an event. We cannot have likelihood of an object.

Look at choice E -
a scale that rates the likelihood of a particular asteroid or comet that may collide with Earth.

The part in orange is modifying comet. So we are essentially saying - likelihood of a particular type of comet. This is wrong.

C is incorrect as how likely X will be to is an incorrect idiom. Correct - how likely is X

A and B have modifier issues.

D is right.

@niksworth : An interestin point you have raised and it is mother of many diffuclt types of errors to catch, especially when in hurry. I have seen this pattern in many questions.
