我是勤劳的搬运工，摘自gmatclub：选D
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
PROBLEM: "Responding to..." is a participial phrase modifying a noun, so the noun has to come right after the comma. The astronomers responded, not the scale.

B. a scale that astronomers have developed rates how likely it is for a particular asteroid or comet to
PROBLEM: Same as above.

C. astronomers have developed a scale to rate how likely a particular asteroid or comet will be to
PROBLEM: You can't say "likely...will be to". It's gibberish. Your ear would recognize that if there weren't all those words in between, confusing things. Try a short example. You should always be able to replace "likely" with "probably".

My program determines how likely you will be to love me.
My program determines how probably you will be to love me...MAKES NO SENSE!

D. astronomers have developed a scale for rating the likelihood that a particular asteroid or comet will
ANSWER

E. astronomers have developed a scale that rates the likelihood of a particular asteroid or comet that may
PROBLEM: You can't have a likelihood of something that may happen. It's the likelihood that something WILL happen.

Hope that helps!

D.  astronomers have developed a scale for rating the likelihood that a particular asteroid or comet will

E.   astronomers have developed ascale that rates the likelihood of a particular asteroid orcomet that may

个人认为，E还存在语义错误：the likelihood of a particular asteroid or comet that may collide with Earth. likelihood of逻辑上的宾语应该是小行星撞击地球，而不是小行星的likelihood.

因此，我觉得这里是the likelihood that和thelikelihood of 的区别，同样的例子有：

Despitethe growing number of people who purchase plane tickets online, airlineexecutives are convinced that, just as one-third of bank customers still preferhuman tellers to automatic teller machines, many travelers will stilluse travel agents.

这是正确选项，错误选项有：

D. fact that thenumber of people purchasing plane tickets online is growing, airline executivesare convinced, just as one-third of bank customers still prefer human tellersas compared to automatic teller machines, that many travelers would

这个选项错误的原因其中有：原句是“尽管某些数字增长”，而此选项中是“尽管某些事实”，语义改变，理同本题的thelikelihood that和thelikelihood of 的区别。

另外，再看另外一个例子：

the rate ofpeople consuming fatty foods is… ；

这两个句子都犯了这样的错误：of的宾语应该是of后紧跟名词的修饰语(即consumingfatty foods), 是消费发胖食物的rate,而不是people的rate。所以要分清of逻辑上的宾语到底是谁。

记得RON说过，of + n. + v-ing在GMAT中99%都是错的，因为of的宾语往往是v-ing,而不是n.
