Now this SC is just beyond my understanding. Correct answer is D.
I rejected because develop for rating….is not the correct idiom. I chose C because in E Likelihood or may is one and same thing. So both together are redundant. But I still don't know why D is correct. One thing GMAC doesn't give explanation sucks.

Do you know how to move this question to SC section by mistake I put it to CR section.
The problem is that this question is from GMAC and we can't even question their credibility. It has to be correct.

A couple of requests have come my way for help on this one.

"Responding to..." describes the astronomers, not the scale, so the first two choices are out.

The last choice refers to "the likelihood of an asteroid or comet". That doesn't make sense; a physical object doesn't have a "likelihood". We can only talk about the likelihood that something will happen.

--

The hard part is choosing between C and D.

First, consider the intended meaning. We're interested in the current likelihood that the comet/asteroid will strike Earth in the future..
In other words, How likely is it NOW that a comet/asteroid WILL STRIKE Earth?

This distinction comes into play when you look at the verbs in C and D. Different verbs.

C mentions "how likely a comet/asteroid will be". Nope. The likelihood is something that exists now, not in the future. (That's the definition of "likelihood": How probable does this event seem right now?
There's no "future likelihood" here. In the future, the event either happens or doesn't happen.)

D mentions the likelihood that a comet/asteroid will collide (in the future) with Earth. That makes sense.

You can also strike A and E because "likelihood" + "may" is redundant.

Hi Ron,

I eliminated choice A B and E easily based on the errors. however, i chose C over D. I thought developed something to do something is correct idiom. It's not developed something for doing something.( please correct me if I am missing something)

Also in your explanation you have mentioned that likelihood and will are two words that can't go together. But D also has "likelihood" and "will".

Sorry for the trouble but I want to get this right for the next time.

Thanks heaps,
Rakesh

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
Nice Share rakesh!

After removing warmups the statement becomes:
Responding to the public's fascination asteroids, a scale developed by astronomers rates the likelihood that a particular asteroid or comet may collide with Earth.

A scale cannot respond and do something; so A and B are out.
Out of C, D, E->
C will be to collide seems awkward
D has the correct idiom form --> It is likely that
E likelihood of a asteroid/comet that may collide seems awkward

Answer D

Vivek

I wrote two things:

1/
"likelihood" + "may" = redundant.

2/
In this context, you can't say that a likelihood will be something, because, in the present context, the "likelihood" is a probability that exists in the present.


Quote:
But D also has "likelihood" and "will".
In D, "will" is associated with the comet/asteroid, and is not associated with "likelihood".

By the way, if you're trying to memorize these specific combinations of words, that's not going to work on the exam. The GMAT is not going to give you another question with exactly the same words.
What you need to take from this question is the attitude of thinking carefully about which things are present/future/past/whatever.
It's impossible to memorize your way to success here. You have to think.

Just to underscore this point -- In a different context, one could have a present likelihood vs. a future likelihood.

E.g.,
If interest rates rise, the likelihood of foreclosures will increase.

In this context, we're actually talking about the likelihood of foreclosures now, VERSUS what would happen to that likelihood if interest rates were to increase. Likelihood now vs. likelihood in that hypothetical future case.

In the problem at hand, there's no such thing. There's only one likelihood that the scientists are trying to rate: the probability at present that an asteroid will kill us all.

There's nothing to memorize. There's nothing you even can memorize. (This is good news, by the way.)
