### HideShow timer Statistics

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 craters 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.

If the meteorite impacts have been scattered fairly evenly over earth surface and then we have greater abundance in geologically stable regions we can say that conclusion is more valid than if the meteorite have high density at some place and low density at some other place ,this would have broke the back of the argument in fact
