C. astronomers have developed a scale to rate how likelya particular asteroid or comet will be to
D. astronomers have developed a scale for rating the likelihood that a particular asteroid or comet will

CDE中选  答案到底是什么

C吧，D的for不对，E的likelihood应该是指代行星撞地球整件事，不是a particular asteroid or comet

本来我也是很确定的 但是网上一查 发现有人找到了 1999NYtimes的原文 Astronomers Adopt Doomsday Index

. .To help deal with public fascination -- and sometimes undue alarm -- about possible threats from asteroids, astronomers have adopted a scale that rates the likelihood that a particular asteroid or comet will collide with Earth.

结果不是和E很像么

这句原文里that后面的事件指代likelihood是正确的，但是你看看E是likelihood of a particular asteroid or comet，不是彗星撞地球这件事，那就不对了

likelihood只能加that 毋庸置疑  这里c明显更好 更简练
