Impact craters caused by meteorites smashing into Earth have been found all around the globe, but they have been found in the greatest density in geologically stable regions. This relatively greater abundance of securely identified crater in geologically stable regions must be explained by the lower rates of destructive geophysical processes in those regions.
The conclusion is properly drawn if which one of the following is assumed?
(A) A meteorite that strikes exactly the same spot as an earlier meteorite will obliterate all traces of the earlier impact.
(B) Rates of destructive geophysical processes within any given region vary markedly throughout geological time.
(C) The rate at which the Earth is struck by meteorites has greatly increased in geologically recent times.
(D) Actual meteorite impacts have been scattered fairly evenly over the Earth’s surface in the course of Earth’s geological history.
(E) The Earth’s geologically stable regions have been studied more intensively by geologists than have its less stable regions.

The author is trying to prove that "the geologically stable regions has lower rates of destructive geophysical processes than in any other regions". The reason he sites for this is the greater density of craters. But if most of the craters had smashed into the earth in that region alone, then the arguement will fail. D does the opposite.

My answer choice would be D.

I will pick D for this.
In the problem it is concluded that :
' must be explained by the lower rates of destructive geophysical processes in those regions '
D states that ' Actual meteorite impacts have been scattered fairly evenly over the Earth’s surface '.
This means that due to lack of destructive geophysical processes in stable regions ,the craters could be identified as compared to other unstable regions where destructive geophysical processes might have removed their traces.

^ D ^

The argument says that craters have been created all over the earth, however, the geophysical destructions wore away their tracks in geologically active places. So, in geologically stable places it is more common to see craters.

If we assume D the conlusion in the argument works, because it puts forward the difference between geologically stable and active places.

Nice. D is good here.

If we negate D conclusion no longer hold.
