The conventional view is that asteroids strike the earth at random locations, thereby randomly affecting various aspects of the earth’s evolution. One iconoclastic geophysicist claims instead that asteroids have struck the earth through a highly organized natural process. Cited as evidence is the unusual pattern of impact craters that form a halo-like swath across the Northern Hemisphere. There is a consensus that these craters appeared at the end of the Cretaceous period, followed by a mass extinction of much land and ocean life. Which one of the following, if true, would most help to support the iconoclastic geophysicist’s claim?
(A) Several asteroid strikes within a short period could produce both volcanic activity that warms the oceans and atmospheric debris that blocks sunlight, and such changes could cause mass extinctions.
(B) ...
(C) ...
(D) ...
(E) ...
